Abstract
Introduction Objective: to determine the effect of gestational weight gain and perinatal outcomes in obese women who underwent and did not undergo bariatric surgery. Material and methods: a retrospective observational cohort study was conducted. The gestational weight gain was classified as insufficient, adequate or excessive according to the guidelines of the United States Institute of Medicine: 4.99-9.07 kg for body mass index (BMI) > 30 kg/m2. Weight gain was calculated as the difference between the weight at the first visit of the 1st trimester and the weight at the visit of the 3rd trimester. Outcomes examined included antepartum variables (gestational diabetes, gestational hypertension, preeclampsia, premature rupture of membranes, placenta previa, placental abruption, intrauterine growth retardation, chorioammionitis, spontaneous abortion), intrapartum variables (induced delivery, vaginal delivery, vacuum, forceps delivery, cesarean section, shoulder dystocia), postpartum variables (postpartum hemorrhage, need for postpartum transfusion, postpartum anemia, need for emergency care, maternal death, postpartum tear, postpartum thrombosis) and neonatal variables (preterm delivery, weight percentile > 90, weight percentile < 10, Apgar score < 7, malformations). Using the statistical package SPSS 22.0, a statistical analysis of the data was performed. Results: two hundred and fifty-six women were recruited; 38 (14.58 %) were pregnant after bariatric surgery and 218 (85.15 %) were pregnant women with obesity who had not been operated on. Of the pregnant women with obesity who had not been operated on, 119 (46.68 %) had grade 1 obesity (BMI 30-34.9), and 99 (38.67 %) had grade 2 and 3 obesity (BMI > 35). A global and subgroup analysis was performed. In the overall analysis, 78 (30.46 %) had insufficient gain, 117 (45.70 %) had adequate gain, and 61 (23.82 %) excessive gain. Overall, insufficient weight gain was associated with a lower probability of gestational hypertension (p < 0.015) and forceps delivery (p < 0.000) and large for gestational age newborn (p < 0.000). On the other hand, insufficient weight gain was associated with a higher probability of intrauterine growth retardation (p 0.044), peripartum infection (0.022), preterm delivery (0.006), and delivery < 35 weeks (p 0.016). Excessive weight gain was associated with a higher probability of gestational hypertension (p 0.025), induced labor (p 0.009), forceps delivery (p 0.011) and large for gestational age newborn (p 0.006). Pregnancies after bariatric surgery had fewer overall complications compared to the other groups. Conclusions: insufficient and excessive weight gain worsens perinatal outcomes. Adequate weight gain does not increase complications and produces some benefits.

Abstract
The global surge of obesity amongst women of reproductive age has raised concerns surrounding the health consequences for their offspring as there is a formidable link between an obesogenic maternal environment and the developmental programming of metabolic dysfunction in the offspring. Specifically, the offspring of mothers with obesity have a three-fold higher risk of developing metabolic-associated fatty liver disease (MAFLD) compared to the offspring of healthy-weight mothers. Given the burgeoning burden of obesity and its comorbidities, it is essential to focus research efforts on methods to alleviate the intergenerational onset of obesity and MAFLD. This review summarizes the current research surrounding the developmental programming of MAFLD in the offspring of mothers with obesity and examines the potential for weight interventions to prevent such metabolic dysfunction in the offspring. It focuses on the benefits of pre-pregnancy interventional strategies, including dietary and exercise intervention, to ameliorate adverse liver health outcomes in the offspring. The utility and translation of these interventions for humans may be difficult for prospective mothers with obesity, thus the use of pre-pregnancy therapeutic weight loss aids, such as glucagon-like peptide-1 receptor agonists, is also discussed.

Abstract
INTRODUCTION Bariatric surgery (BS) leads to substantial weight loss accompanied by reversal of several obesity-related co-morbidities and reduced mortality. However, surgery is associated with risks and its nearly irreversible characteristic requires a clearly established pre- and postoperative clinical pathway. In France, this pathway relies on recommendations made by the High Authority of Health (Haute Autorité de santé (HAS)) in 2009; an update is awaited in 2023. PREOPERATIVE ASPECTS BS should be proposed only after failure of well-conducted medical treatment and is intended for patients whose body mass index (BMI) is ≥40kg/m2 or for those with BMI ≥35kg/m2 who also have co-morbidities amenable to improvement, and in whom there are no contra-indications, particularly, those related to general anesthesia or psychological factors. The success and safety of surgical management requires preparation of the patient with regard to dietetic and nutritional counseling, and physical activity. The possibility of complications must be recognized and communicated, including, in view of the large variability of outcomes between individuals, the risk of failure and regain of weight. POSTOPERATIVE ASPECTS Prior to the operation, patients should be informed of and accept the program of postoperative clinical and laboratory follow-up, as well as the need for lifelong supplementation in micronutrients and the financial implications including what patients may have to pay out of their own pocket. CONCLUSION Surgical management of obesity cannot replace the multidisciplinary medical management of severe obesity. The results obtained by BS are sustainable only if the patient adheres to the proposed modalities. New drugs such a GLP-1 analogues have opened encouraging perspectives as possible alternatives to BS in certain indications.

Abstract
INTRODUCTION Women with overweight and obesity, and their children, are at increased risk of adverse pregnancy, birth, and longer term health outcomes, believed to be compounded by excessive gestational weight gain (GWG). Research to date has focused on interventions to reduce excessive GWG through changes to maternal diet and/or lifestyle. AREAS COVERED Current clinical recommendations for GWG vary according to a woman's early pregnancy body mass index, based on assumptions that associations between GWG and adverse pregnancy outcomes are causal in nature, and modifiable. While there are small differences in GWG following pregnancy interventions, there is little evidence for clinically relevant effects on pregnancy, birth, and longer term childhood outcomes. This review considers interventional studies targeting women with overweight or obesity to reduce GWG in an effort to improve maternal and infant health, and the current evidence for interventions prior to conception. EXPERT OPINION GWG is not modifiable via diet and lifestyle change, and continued efforts to find the 'right' intervention for women with overweight and obesity during pregnancy are unjustified. Researchers should focus on gathering evidence for interventions prior to pregnancy to optimize maternal health and weight to improve pregnancy, birth, and longer term health outcomes associated with obesity.

Abstract
BACKGROUND To summarize evidence of benefits and risks of maternal and neonatal outcomes among pregnant women after Roux-en-Y gastric bypass surgery. METHODS A systematic search was conducted in MEDLINE, EMBASE, Web of Science, Ovid and Cochrane Library until 24th May 2021. Inclusion criteria were randomized trails or observational studies including at least one of maternal or neonatal outcomes from pregnant women who had a history of Roux-en-Y gastric bypass surgery with a control group of pregnant women with no history of bariatric surgery. Non-English studies were excluded. Both fixed-effect and random-effect models were used in the meta-analyses. Newcastle-Ottawa Scale was used to assess quality of studies. RESULTS Nine retrospective articles were eligible including 13 848 pregnant women with a history of Roux-en-Y gastric bypass surgery and 255 008 pregnant women without a history of bariatric surgery. The results of meta-analysis showed a lower incidence of preterm premature rupture of membranes (OR 0.53, 95% CI [0.47, 0.60], p < 0.00001), large gestational age infants (OR 0.28, 95%CI [0.22, 0.37], p < 0.00001) or macrosomia (OR 0.26, 95%CI [0.23, 0.30], p < 0.00001) in women after Roux-en-Y gastric bypass surgery. On the other hand, infants born to mothers with a history of Roux-en-Y gastric bypass surgery had an increased risk of small gestational age (OR 2.24, 95% CI [1.55, 3.24], p < 0.00001). CONCLUSION Roux-en-Y gastric bypass surgery reduces significantly of risks of preterm premature rupture of membranes and large for gestational age/ macrosomia, but increase the risk of small for gestational age.

Abstract
INTRODUCTION Obesity has a derogatory effect on female reproductive health. Obesity contributes to difficulty in natural conception, increased risk of pregnancy-associated complications, miscarriages, congenital anomalies, and also the long-term negative impact on both mother and the child. OBJECTIVES Our study aimed to analyze and assess the reproductive health-associated outcomes of females who underwent bariatric surgery. METHODS We performed a retrospective analysis from a prospectively collected database from June 2013 to June2016. Out of 71 females studied, 45 patients (63.5%) had completed 3 years of follow-up. The data were collected from inpatient and outpatient records. Patients were studied under three groups (A, patients with polycystic ovarian disease (PCOD) symptoms; B, patients with primary infertility; and C, patients who conceived after bariatric surgery that were included in groups A and B). RESULTS Out of 45 patients studied, 40 patients underwent laparoscopic sleeve gastrectomy (LSG), four patients underwent laparoscopic Roux-en-Y gastric bypass (RYGB), and one patient underwent laparoscopic adjustable gastric banding (LAGB). The mean BMI of the patients was 43.64 ± 6.8 kg/m2. PCOD symptoms improved symptomatically (p = 0.001) after surgery in the group. Seven (43.75%) primary infertility patients conceived after surgery. Three (42.9%) patients conceived naturally while 4 (57.1%) conceived with ART in group B. Out of total population of 45 in group C, percentages of patients who delivered baby with short gestational age (SGA), low birth weight (LBW), normal vaginal deliveries (NVD), and maternal anemia were 63.15%,47.3%,73.4%, and26.3%, respectively. CONCLUSION Obesity is closely associated with primary infertility and PCOD. Menstrual abnormalities associated with PCOD significantly improve after bariatric surgery with significant improvement in fertility along with maternal outcomes.

Abstract
BACKGROUND Women who undergo bariatric surgery prior to pregnancy are less likely to experience comorbidities associated with obesity such as gestational diabetes and hypertension. However, bariatric surgery, particularly malabsorptive procedures, can make patients susceptible to deficiencies in nutrients that are essential for healthy fetal development. The objective of this systematic review and meta-analysis is to investigate the association between pregnancy after bariatric surgery and adverse perinatal outcomes. METHODS AND FINDINGS Searches were conducted in Medline, Embase, PsycINFO, CINAHL, Scopus, and Google Scholar from inception to June 2019, supplemented by hand-searching reference lists, citations, and journals. Observational studies comparing perinatal outcomes post-bariatric surgery to pregnancies without prior bariatric surgery were included. Outcomes of interest were perinatal mortality, congenital anomalies, preterm birth, postterm birth, small and large for gestational age (SGA/LGA), and neonatal intensive care unit (NICU) admission. Pooled effect sizes were calculated using random-effects meta-analysis. Where data were available, results were subgrouped by type of bariatric surgery. We included 33 studies with 14,880 pregnancies post-bariatric surgery and 3,979,978 controls. Odds ratios (ORs) were increased after bariatric surgery (all types combined) for perinatal mortality (1.38, 95% confidence interval [CI] 1.03-1.85, p = 0.031), congenital anomalies (1.29, 95% CI 1.04-1.59, p = 0.019), preterm birth (1.57, 95% CI 1.38-1.79, p < 0.001), and NICU admission (1.41, 95% CI 1.25-1.59, p < 0.001). Postterm birth decreased after bariatric surgery (OR 0.46, 95% CI 0.35-0.60, p < 0.001). ORs for SGA increased (2.72, 95% CI 2.32-3.20, p < 0.001) and LGA decreased (0.24, 95% CI 0.14-0.41, p < 0.001) after gastric bypass but not after gastric banding. Babies born after bariatric surgery (all types combined) weighed over 200 g less than those born to mothers without prior bariatric surgery (weighted mean difference -242.42 g, 95% CI -307.43 to -177.40 g, p < 0.001). There was low heterogeneity for all outcomes (I2 < 40%) except LGA. Limitations of our study are that as a meta-analysis of existing studies, the results are limited by the quality of the included studies and available data, unmeasured confounders, and the small number of studies for some outcomes. CONCLUSIONS In our systematic review of observational studies, we found that bariatric surgery, especially gastric bypass, prior to pregnancy was associated with increased risk of some adverse perinatal outcomes. This suggests that women who have undergone bariatric surgery may benefit from specific preconception and pregnancy nutritional support and increased monitoring of fetal growth and development. Future studies should explore whether restrictive surgery results in better perinatal outcomes, compared to malabsorptive surgery, without compromising maternal outcomes. If so, these may be the preferred surgery for women of reproductive age. TRIAL REGISTRATION PROSPERO CRD42017051537.

Abstract
BACKGROUND Bariatric procedures are on the rise. The risk of birth defects in pregnancies following such procedures may be increased (eg, due to nutrient deficiencies) or decreased (eg, due to decreased maternal body mass index, BMI). METHODS We conducted a systematic literature review of the association between bariatric surgery and birth defects using Ovid MEDLINE and PubMed (1946-2017). Information was abstracted on study design, exposures, outcomes, covariates and estimates of association. RESULTS Fifteen studies met our inclusion criteria: 14 evaluated the outcome of any birth defect, and one evaluated neural tube defects. Estimates of association between bariatric surgery and birth defects were available for nine studies and ranged from 0.6 to 1.9 (all 95% confidence intervals included 1.0). When studies were stratified by surgery type, there was no obvious pattern of association. When stratified by the approach used to account for BMI, positive associations were observed in studies that did not account for maternal prepregnancy BMI or used women with normal BMI as the reference group (range: 1.3-1.9). Estimates from studies that either matched or adjusted for prepregnancy BMI were closer to the null (range: 1.1-1.2) and studies that compared to morbidly obese women reported protective associations (range: 0.6-0.7). CONCLUSIONS Studies of the association between bariatric surgery and birth defects vary with respect to the surgical procedures included, birth defects ascertainment methods and approaches used to account for maternal BMI. Consequently, it is not possible to draw a conclusion regarding the association between bariatric surgery and birth defects. Additional studies are warranted.

Abstract
BACKGROUND An increased risk of small-for-gestational-age infants after maternal bariatric surgery has been shown. The risk of micronutrients deficiencies in these neonates is unclear. OBJECTIVE To screen for micronutrients deficiencies in newborns of mothers with gastric bypass. SETTINGS University hospital in Angers, France. METHODS This study compared the clinical and cord blood biological characteristics of 56 newborns of mothers with prior Roux-en-Y gastric bypass (RYGB) and 56 newborns of nonobese healthy mothers after normal pregnancy (controls), followed between January 3, 2008 and October 31, 2012. Cord blood micronutrients concentrations from controls were used for establishing normative data. After RYGB, the women took daily micronutrients supplements. RESULTS RYGB mothers lost 18.1±6.3 kg/m2 of body mass index (BMI) in the 11-69 months between surgery and pregnancy onset (percentage of excess weight loss 79±20%), reaching BMI of 30.1±6.0 kg/m2 compared with 22.3±4.0 kg/m2 in the controls (P<.05). Neonates born to RYGB mothers were small-for-gestational-age in 23% of cases versus 3.6% in the control group (P<.01). A higher percentage of RYGB neonates had cord blood concentrations below the 2.5 percentile for calcium (19% versus 2%), zinc (13% versus 3%,), iron (19% versus 2%), and vitamin A (13% versus 3%), and over the 97.5 percentile for magnesium (13% versus 3%), vitamin E (16% versus 3%), 25-hydroxy-vitamin D (13% versus 2%), and vitamin B12 (14% versus 2%) (P<.05 for all comparisons). CONCLUSION Neonates from RYGB mothers showed cord blood micronutrient differences compared with neonates from healthy mothers. The comparison with neonates from morbidly obese women is still to be done.

Abstract
OBJECTIVE To assess obstetrical and neonatal outcomes in women following gastric bypass, compared with adipose women without surgery and with a normal weight control population. DESIGN Historical controlled cohort study. SETTING Denmark. POPULATION All women undergoing gastric bypass during the period 1996-2011, and subsequently giving birth. METHODS AND MAIN OUTCOME MEASURES Obstetrical and neonatal outcomes in women without gastric bypass matched on age, parity, plurality, year, and body mass index, and normal weight women. RESULTS In 415 women giving birth after gastric bypass we found significantly more women with hypertension in pregnancy; relative risk (RR) 2.5 (95% confidence interval 1.3-5.0), gestational diabetes; RR = 6.9 (3.5-13.5), and acute abdominal pain during pregnancy; RR = 4.7 (2.9-7.8) compared with normal weight controls. Compared with women with similar body mass index, they had a lower incidence of preeclampsia and emergency cesarean sections, and their children a lower incidence of asphyxia; RR = 0.4 (0.2-0.8). Their children were on average 212 g smaller than newborn of normal weight mothers, and 319 g smaller than newborn of adipose controls, and had significantly more admissions to neonatal intensive care unit compared with newborn of normal weight mothers; RR = 1.5 (1.1-2.0). CONCLUSIONS Gastric bypass may reduce the risk of preeclampsia, emergency cesarean section, and perinatal asphyxia, compared with adipose women without surgery. Compared with normal weight controls women who had had a gastric bypass had a higher risk of hypertension, gestational diabetes, and acute abdominal pain during pregnancy and their children a lower birthweight and higher incidence of admittance to neonatal intensive care.

Abstract
Bariatric surgery is gaining in popularity, due to globally increasing rates of obesity. In the UK, this has manifested as a 14-fold increase in bariatric surgery between 2004 and 2010, making it necessary to develop strategies to manage women who become pregnant following bariatric surgery. This review paper has explored all the current evidence in the literature and provided a comprehensive management strategy for pregnant women following bariatric surgery. The emphasis is on a multidisciplinary team approach to all aspects of care. Adequate pre-conception and antenatal and postnatal care is essential to good pregnancy outcomes with emphasis on appropriate nutritional supplementation. This is especially important following malabsorptive procedures. There is no evidence to suggest that pregnancy outcome is worse after bariatric surgery, though women who remain obese are prone to obesity-related risks in pregnancy. Neonatal outcome post-bariatric surgery is no different from the general population.

Abstract
OBJECTIVE To describe early and late fetal growth in pregnancies conceived after gastric bypass surgery in relation to time from surgery to conception of pregnancy. METHODS National cohort study on 387 Danish women, who had laparoscopic or open gastric bypass surgery prior to a singleton pregnancy in which first trimester screening was performed between January 2008 and June 2011. Data were derived from national registers (Danish National Registry of Patients and Danish National Birth Registry, Pregnancy Complications and Abortion-clinical quality database (PreCAb) and the Danish Fetal Medicine Database). Main outcome measures were early and late fetal growth in relation to time from bariatric surgery to conception of the pregnancy. Early fetal growth was expressed as "Fetal Growth Index": the ratio between the estimated number of days from first trimester ultrasound to second trimester ultrasound biometries and the actual calender time elapsed in days. Late fetal growth was expressed as the observed versus expected birthweight according to gestational age (GA). RESULTS The surgery-to-conception interval ranged from 3 to 1851 days with a mean value of 502 (SD, 351) days. The mean "fetal growth index" was 0.99 (SD, 0.02) days/day and thus significantly lower than in the background population (mean, 1.04 (SD, 0.09) days/day, p<0.0001). The proportion of infants being small for gestational age was 18.8% and the proportion of large for gestational age infants was 6.7%. The correlation coefficients between surgery-to-conception time and "fetal growth index" and birthweight according to GA were 0.01 (p = 0.8) and 0.04 (p = 0.4), respectively. CONCLUSION Fetal growth index was lower than reported in the background population. No correlation was found between the surgery-to-conception interval and early or late fetal growth in pregnancies conceived after gastric bypass surgery.

Abstract
OBJECTIVE To compare perinatal outcomes in births of women with versus without a history of bariatric surgery. DESIGN Population based matched cohort study. SETTING Swedish national health service. PARTICIPANTS 1,742,702 singleton births identified in the Swedish medical birth register between 1992 and 2009. For each birth to a mother with a history of bariatric surgery (n=2562), up to five control births were matched by maternal age, parity, early pregnancy body mass index, early pregnancy smoking status, educational level, and year of delivery. Secondary control cohorts, including women eligible for bariatric surgery (body mass index ≥ 35 or ≥ 40), were matched for the same factors except body mass index. History of maternal bariatric surgery was ascertained through the Swedish national patient register from 1980 to 2009. MAIN OUTCOME MEASURES Preterm birth (<37 weeks), small for gestational age birth, large for gestational age birth, stillbirth (≥ 28 weeks), and neonatal death (0-27 days). RESULTS Post-surgery births were more often preterm than in matched controls (9.7% (243/2511) v 6.1% (750/12,379); odds ratio 1.7, 95% confidence interval 1.4 to 2.0; P<0.001). Body mass index seemed to be an effect modifier (P=0.01), and the increased risk of preterm birth was only observed in women with a body mass index <35. A history of bariatric surgery was associated with increased risks of both spontaneous (5.2% (130/2511) v 3.6% (441/12,379); odds ratio 1.5, 1.2 to 1.9; P<0.001) and medically indicated preterm birth (4.5% (113/2511) v 2.5% (309/12,379); odds ratio 1.8, 1.4 to 2.3; P<0.001). A history of bariatric surgery was also associated with an increased risk of a small for gestational age birth (5.2% (131/2507) v 3.0% (369/12,338); odds ratio 2.0, 1.5 to 2.5; P<0.001) and lower risk of a large for gestational age birth (4.2% (105/2507) v 7.3% (895/12,338); odds ratio 0.6, 0.4 to 0.7; P<0.001). No differences were detected for stillbirth or neonatal death. The increased risks for preterm and small for gestational age birth, as well as the decreased risk for large for gestational age birth, remained when post-surgery births were compared with births of women eligible for bariatric surgery. CONCLUSION Women with a history of bariatric surgery were at increased risk of preterm and small for gestational age births and should be regarded as a risk group during pregnancy.

Abstract
Obesity is associated with multiple adverse reproductive outcomes, but the mechanisms involved are largely unknown. Obesity has been referred to as a "complex system," defined as a system of heterogeneous parts interacting in nonlinear ways to influence the behavior of the parts as a whole. Human reproduction is also a complex system; hence the difficulty in identifying the mechanisms linking obesity and adverse reproductive function. This review discusses the adverse reproductive outcomes associated with obesity and the mechanisms involved and concludes with a discussion of public health policy with respect to the treatment of infertility in obese women.

Abstract
OBJECTIVE To estimate the rates of pregnancy outcomes of women after bariatric surgery relative to women in a control groups. METHODS The study was a chart review. Presurgery and prepregnancy body mass index (BMI) were calculated for 70 patients who had undergone bariatric surgery and who had a subsequent singleton pregnancy. Four control patients were then randomly selected for each case patient: two with a BMI within 6 points of the average presurgery BMI and two with a BMI within 6 points of the average prepregnancy BMI. The primary outcomes were the rates of gestational diabetes or hypertensive disorders of pregnancy. RESULTS There was a significant decrease in rate of gestational diabetes in bariatric surgery patients (0.0%) as compared with both control groups (morbidly obese 16.4%, obese 9.3%; corrected odds ratio (OR)morbidly obese 0.04, with a 95% confidence interval [CI] 0.00-0.62, P<.01; corrected OR obese 0.07, CI 0.00-1.20, P=.01). There was no significant difference in the rate of hypertensive disorders of pregnancy with bariatric surgery. Additionally, neonates were significantly more likely to be small for gestational age (SGA) in the bariatric surgery group (17.4%) than the morbidly obese group (5.0%) (OR 3.94, CI 1.47-10.53, P<.01). CONCLUSION Bariatric surgery is associated with reduction in gestational diabetes in a subsequent pregnancy, but possibly at the expense of an increase in SGA neonates.

Abstract
UNLABELLED With the increase in the number of bariatric surgeries being performed in women of childbearing age, physicians must have concerns regarding the safety of pregnancy after bariatric surgery. The aim of this review is to summarize the literature reporting on maternal, obstetrical and perinatal implications of pregnancy following BS. METHODS English, Spanish and Portuguese-language articles were identified in a PUBMED search from 2005 to February 2011 using the keywords for pregnancy and bariatric surgery or gastric bypass or gastric banding. RESULTS The studies show improved fertility and a reduced risk of gestational diabetes, pregnancy-induced hypertension and pre-eclampsia, macrosomia in pregnant women after bariatric surgery. The incidence of intrauterine growth restriction and small for gestational age are increased. No conclusions can be drawn concerning the risk for cesarean delivery and the best surgery-to-conception interval. Deficiencies in iron, vitamin A, vitamin B12, vitamin K, folate and calcium can result in maternal and fetal complications. CONCLUSIONS Pregnancy outcome of women who delivered after BS, as compared to obese populations, is better and safer and comparable to the general population. Close supervision before, during and after pregnancy following bariatric surgery and nutrient supplementation adapted to the patient's individual requirements can prevent nutrition-related complications and improve maternal and fetal health.

Abstract
The number of bariatric surgeries performed in the United States has increased exponentially. Given that most patients are female and of reproductive age, it is important for clinicians who manage women's health issues to be aware of the surgery, its long-term goals, and the potential effect on future pregnancies. Most pregnancies after bariatric surgery have successful outcomes with decreased occurrences of gestational diabetes and hypertension and lower birth weight compared with control patients. Following nutritional guidelines and supplementation in the event of deficiencies are critical in the provision of prenatal care to this unique population. Other important issues include a multidisciplinary team management, a different approach to screening for gestational diabetes, careful evaluation of any gastrointestinal complaints, and appropriate counseling for gravidas who still remain obese during pregnancy. Further research should investigate the long-term maternal outcomes in pregnancies after bariatric surgery as well as the effect on the offspring.

Abstract
OBJECTIVE In a large, prospective Swedish national cohort, we investigated individual birth characteristics for women who had undergone bariatric surgery and their obstetric outcome and made comparisons with all other women during the same period. STUDY DESIGN The cohort consisted of 494,692 women born 1973-1983 of which 681 women who had undergone bariatric surgery constituted the index group. RESULTS The index women more often have parents with lower sociodemographic status and are more often born large for gestational age. The women surgically treated before their first child had a shorter gestational length, their children had lower birthweight, and were more often born small for gestational age compared with the children born to the reference mothers. Women whose child was born before their bariatric surgery more often had a cesarean section, and their children were more often large for gestational age. CONCLUSION Preconception bariatric surgery in obese women may be associated with improved obstetric outcomes.

Abstract
OBJECTIVE To compare pregnancy outcomes postbariatric surgery for women who remain obese at conception to those who were not obese. METHODS From a database of women who received outpatient perinatal services, we identified women with a history of bariatric surgery who are currently pregnant with a singleton gestation. Available maternal characteristics and pregnancy outcomes were compared between women whose prepregnancy body mass index (PPBMI) remained in the obese range (≥30 kg/m(2)) and those with a PPBMI of <30 kg/m(2) using Fisher exact test, independent Student's t test, and Mann-Whitney U test statistics. RESULTS Of the 102 women identified, 52 (51%) were obese and 50 (49%) were not obese at conception. No differences were observed in maternal age, marital status, years from surgery to delivery, development of gestational diabetes, gestational age at delivery, neonatal intensive care unit (NICU) admission, or nursery days. Maternal obesity (≥30 kg/m(2)) postbariatric surgery was associated with higher rates of cesarean delivery (63.5% vs. 36.0%, p=0.010) and development of pregnancy-related hypertension (36.5% vs. 8.0%, p=0.001) compared to nonobese women (<30 kg/m(2)). CONCLUSIONS Postbariatric surgery, an optimal goal should be to achieve a nonobese weight status before conception to reduce maternal complications, such as pregnancy-related hypertension and cesarean delivery.

Abstract
BACKGROUND Approximately 80% of patients undergoing bariatric surgery are women, and about one half of these are of reproductive age. The purpose of the present study was to compare laparoscopic adjustable gastric banding (LAGB) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in a series of morbidly obese women with respect to maternal and neonatal outcomes at a university hospital in France. METHODS From January 2004 to December 2008, the data from women who had undergone LAGB or LRYGB at our center and were pregnant were collected, including age, parity, gravidity, weight, body mass index (BMI) before surgery and at scheduled intervals after surgery (1, 3, 6, 12, and 18 mo and yearly thereafter), interval from surgery to conception, weight and BMI at conception, weight and weight gain during pregnancy, weight and BMI at 2 weeks after pregnancy, complications during pregnancy, gestational age, method of delivery, fetal birth weight, and fetal outcome. RESULTS There were 42 pregnancies in 36 women, 22 in women who had undergone LAGB and 20 who had undergone LRYGB. The LAGB and LRYGB groups were comparable for all analyzed variables, except that the preoperative weight and BMI were greater in the LRYGB group. No differences in weight or BMI were found at conception or after pregnancy. No difference was found between the 2 groups in terms of obstetric complications or neonatal outcomes. A high frequency of cesarean deliveries was necessary in both groups. CONCLUSIONS The results of the present study have shown that no significant difference exists in the obstetric and birth outcomes between women who have undergone LRYGB and those who have undergone LAGB.

Abstract
Obesity is a growing problem in obstetric practice. A recent study from Glasgow (UK) showed that 50% of women of childbearing age are either overweight (Body Mass Index [BMI] = 24.9–29.9kg/m2) or obese with 18% starting pregnancy as obese. Obesity prevalence has doubled over a decade from the early 1990’s. In the US it is estimated that 30% of reproductive-age women have a BMI greater than 30 kg/m while 7% have a BMI > 40 kg/m2. A recent report from the UK found that 5% of women had a BMI >35 kg/m2, 2% > 40 kg/m2 and 0.2% >50 kg/m2 with an association not only with social deprivation, but also with a higher prevalence of pre-existing medical disorders such as diabetes and hypertension and medical complications of pregnancy such as preeclampsia. Obesity was also associated with increased rates of macrosomia, operative delivery and postpartum haemorrhage. These data highlight the fact that obesity is an increasing health concern particularly in young women of childbearing age. Obesity will expose them to significant pregnancy complications ranging from miscarriage and fetal abnormality through to operative delivery and thromboembolism. There are also challenges for the delivery of maternity care to meet the needs of these women. As obesity is associated with significant pregnancy complications it is important that women enter pregnancy with an optimum body weight. Many complications, such as fetal abnormality occur in the first trimester and so pre-pregnancy weight reduction is preferred. Further, there is insufficient evidence to recommend specific dietary and/or physical activity interventions to reduce weight or moderate weight gain during pregnancy.

Abstract
BACKGROUND The objective of this study was to analyze obstetrical and neonatal outcomes following Roux en Y Gastric Bypass procedures (RYGBP). METHODS A retrospective cohort study was conducted in a single French tertiary perinatal care and bariatric center. The study involved 24 pregnancies, following RYGBP (exposed group) and two different control groups (non-exposed groups). A body mass index (BMI)-matched control group included 120 pregnancies matched for age, parity, and pregnancy BMI. A normal BMI control group included 120 pregnancies with normal BMI (18.5-24.9 kg/m(2)), matched for age and parity. Hospital data were reviewed from all groups in the same 6-year period. Obstetrical and neonatal outcomes after RYGB were compared, separately, to the two different-matched control groups. RESULTS The median interval from RYGBP to conception was 26.6 (range: 3-74) months. Rates of perinatal complications did not differ significantly between the RYGBP group and normal BMI and BMI-matched controls groups. The rate of Cesarean section before labor was higher in the RYGBP patients than in the normal BMI control group (25% vs. 9.3% respectively, p = 0.04). Weight gain was lower in the RYGBP patients than normal BMI control group (5.8 kg vs. 13.2 kg respectively, p < 0.0001). Birthweight was also lower in the RYGBP group than those in normal BMI and BMI-matched controls groups (2,948.2 g vs. 3,368.2 g and 3,441.8 g, respectively, p < 0.0001). CONCLUSIONS RYGBP surgery was associated with reduced birthweight, suggesting a possible role of nutritional growth restriction in pregnancy.

Abstract
In recent years, the prevalence of obesity in the United States has risen dramatically, especially among women of reproductive age. Research that has specifically evaluated pregnancy outcomes among obese parturients has allowed for a better understanding of the myriad adverse perinatal complications that are observed with significantly greater frequency in the obese pregnant population. The antepartum, intrapartum, intraoperative, postoperative, and postpartum periods are all times in which the obese pregnant woman is at greater risk for adverse maternal-fetal outcomes, compared with her ideal bodyweight counterpart. Comorbid medical conditions that commonly are associated with obesity further accentuate perinatal risks. All obese pregnant women should be counseled regarding these risks, and strategies should be used to improve perinatal outcome whenever possible. Obese women of reproductive age ideally should be counseled before conception and advised to achieve ideal bodyweight before pregnancy.

Abstract
The incidence of obesity is increasing rapidly, and it affects a greater proportion of women than men. Unfortunately, obesity has a negative impact on women's reproductive health, including increased adverse perinatal outcomes. Weight loss surgery, also known as bariatric surgery, is performed in many hospitals, and can allow for significant weight loss and improvement in medical comorbidities such as diabetes and hypertension. A woman who becomes pregnant after bariatric surgery usually has an uncomplicated pregnancy but requires special attention to some complications that can occur after these procedures. This article reviews the perinatal outcomes and provides recommendations for care regarding the unique issues that arise during a pregnancy after bariatric surgery.

Abstract
Internal hernias are a specific cause of acute abdominal pain and are a well-known complication after laparoscopic Roux-en-Y gastric bypass for morbid obesity. Although internal hernias are a rare cause of intestinal obstruction, they may evolve towards serious complications, such as extensive bowel ischemia and gangrene, with the need for bowel resection and sometimes for a challenging reconstruction of intestinal continuity. The antecolic position of the Roux limb is associated with a decrease in the incidence of small-bowel obstruction and internal hernias. The best prevention of the formation of these hernias is probably by closure of potential mesenteric defects at the initial operation with a non-absorbable running suture. We present a patient in late pregnancy with a small-bowel volvulus following laparoscopic Roux-en-Y gastric bypass for morbid obesity and discuss the available literature. For a favorable obstetric and neonatal outcome, it is crucial not to delay surgical exploration and an emergency operation usually is mandatory.

Abstract
CONTEXT: The surgical treatment for morbid obesity is becoming common in this country. Only a few papers reported the long-term results of the surgical approach for morbid obesity, mainly in terms of quality of life. OBJECTIVE: To compare mortality rate, weight loss, improvement of both diabetes and hypertension, and quality of life of patients from the public healthcare in Cuiabá, MT, Brazil, who underwent either medical or surgical interventions after a minimum of 2 years. METHODS: The population of this study was constituted by morbidly obese patients who initiated treatment between June 2002 and December 2006. The casuistic consisted of 89 patients submitted to medical therapy and 76 patients who underwent surgical procedures. The main variables were weight loss, improvement of hypertension and diabetes, quality of life, and mortality. RESULTS: The overall results showed that weight loss was significant in the two groups (P<0.001); however surgical patients showed a greater loss than the medical group (P = 0.05). The improvement of diabetes and hypertension was significantly greater in the surgical group (P<0.001), in which no cases of diabetes persisted. There was an increase in cases of hypertension among patients receiving medical attention. Mortality occurred in six cases (6.7%) of the medical group and in five cases (6.6%) of the surgical group (P = 0.97). The median grade of the quality of life score obtained by surgical patients (2.37 [range: -2.50 to 3.00]) was significantly greater (P<0.001) when compared to the medical group (1.25 [range: -1.50 to 3.00]). CONCLUSION: The surgical group presented better results regarding the weight loss, quality of life and improvement of hypertension and diabetes. There was no significant difference in mortality rate between the two groups after a minimum of 2 years.

Abstract
PURPOSE OF REVIEW To explore recent developments in obesity-related topics of interest and importance to obstetricians. Specifically addressed are the impact of gestational weight gain on perinatal risk, the increased risk of congenital anomalies in offspring, developmental origins of health and disease in offspring, and reproductive issues following bariatric surgery. RECENT FINDINGS Limiting maternal weight gain in obese women to less than 15 lb may favorably attenuate perinatal risk (macrosomia, cesarean delivery, preeclampsia) but increase risk for small-for-gestational-age newborns. Obese women are at significantly increased risk for offspring to develop open neural tube defects and congenital heart disease as well as other anomalies. Impaired sonographic visualization in this population may impede prenatal diagnosis of these serious birth defects. Intrauterine nutritional overabundance may cue adaptive fetal responses predisposing to childhood and adult obesity as well as the metabolic syndrome. Bariatric surgery, the only effective treatment for morbid obesity, causes lifelong physiologic and anatomic changes associated with significant reproductive implications. Procedures can predispose to caloric and micronutrient deficiencies, improved fertility and fecundity, and late surgical complications. Pregnancy outcomes are typically similar to those of women without previous bariatric surgery and better than those of untreated morbidly obese women. SUMMARY Obesity and its surgical treatment are associated with lifelong health implications for the mother as well as her offspring. An appreciation of these obesity-related reproductive issues is critical for optimal care of this growing segment of the female population.

Abstract
Bariatric surgery is highly effective for weight loss in morbid obesity. With the high prevalence of severe obesity in the developed world, and the acknowledgement of the effectiveness of these procedures by National Institute for Clinical Excellence (in the UK) and the Food and Drug Administration (in the USA), women with severe obesity will increasingly seek such treatment. As the majority of these patients are women of reproductive age, obstetricians will encounter these patients frequently during pregnancy. It is therefore important for obstetricians to gain an insight into the types of surgery performed, the potential complications, including nutritional deficiency, and appropriate management of pregnancy following weight-loss surgery. In general, bariatric surgery is associated with a reduction in obesity related complication, with no apparent increased risk of adverse perinatal outcomes.

Abstract
BACKGROUND Conception is discouraged during the period of maximal weight loss following Roux-en-Y gastric bypass (RYGB) because of speculative maternal and fetal concerns. We therefore performed a retrospective cohort study of obstetrical and neonatal outcomes by surgery-to-conception interval. METHODS Women with RYGB were stratified into two groups by surgery-to-conception interval of <or=18 or >18 months. Pregnancy and newborn outcomes excluding miscarriages were compared using the chi-square or unpaired t-test for dichotomous and continuous variables, respectively. RESULTS Twenty subjects conceived <or=18 months (11.4+/-5.0) and 32 conceived >18 months (47.5+/-41) after RYGB, p< .05. Maternal age, parity, body mass index, and weight gain were similar by group. There were no statistically significant differences in adverse obstetrical outcomes (preterm premature membrane rupture, gestational diabetes, oligohydramnios, intrauterine growth restriction, preterm or post-term delivery) or adverse newborn outcomes (5-min Apgar score <7, intensive care admission, or birth defect). CONCLUSION Obstetrical and neonatal outcomes are similar in women conceiving during or after the period of maximal weight loss following RYGB.
