[PMID: 37329409 DOI: 10.1007/s11695-023-06678-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 05/30/2023] [Accepted: 06/08/2023] [Indexed: 06/19/2023]
Abstract
INTRODUCTION As the utilization of metabolic and bariatric surgery (MBS) continues to rise, it is important to address the nutritional needs of women who had MBS who become pregnant. Not meeting those nutritional needs could lead to complications associated with malnutrition. To better understand the relationship between MBS, pregnancy, and malnutrition, this study sought to determine whether differences exist in the presence of malnutrition during pregnancy in women with a history of MBS compared to women without a history of MBS. METHODS This cross-sectional study used the National Inpatient Sample (NIS) from 2012 to 2017, which samples 20% of hospital discharges in the USA. Multivariate logistic regression models were fitted, and odds rations and 95% confidence intervals were calculated with obesity and MBS as the independent variables and malnutrition during pregnancy as the dependent variable. Covariates included in the multivariate model were age, primary payer, hypertension, hyperlipidemia, and depression. RESULTS Compared to women who did not have MBS, women who had MBS had higher odds of malnutrition during pregnancy (aOR = 8.33, 95% CI 7.30-9.50), this result was moderated by racial category (aORBlack = 6.35, 95% CI 4.97-8.13; aORwhite = 8.25, 95% CI 7.00-9.73; aORLatina = 10.93, 95% CI 8.38-14.25). Women with obesity also had higher odds of malnutrition during pregnancy. CONCLUSIONS The increased odds of malnutrition among women with MBS suggests that it is important to consider tailoring nutrition recommendations to address the different nutritional needs of pregnant women who had MBS and may be at risk for malnutrition.

Pregnancy characteristics and outcomes after bariatric surgery: national-level analysis in the United States. Surg Obes Relat Dis 2023; 19:364-373. [PMID: 36470811 DOI: 10.1016/j.soard.2022.10.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 09/16/2022] [Accepted: 10/16/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND Bariatric surgery is an effective surgical treatment for weight reduction in individuals with obesity. Pregnancy outcomes related to prior bariatric surgery are currently under active investigation. OBJECTIVE To assess national-level trends, characteristics, and outcomes of pregnancy after bariatric surgery in the United States. SETTING Retrospective cohort study queried the National Inpatient Sample. METHODS The study population was 14,648,135 patients who had vaginal or cesarean delivery from January 2016 to December 2019. Exposure allocation was based on the history of bariatric surgery. The main outcomes were (1) trends and characteristics related to bariatric surgery, assessed with multivariable binary logistic regression model; and (2) Centers for Disease Control and Prevention-defined severe maternal morbidity, assessed by propensity score matching and generalized estimating equation. RESULTS A total of 53,950 (.4%) patients had prior bariatric surgery. The number of patients with prior bariatric surgery increased from .3% to .5%, and this trend remained independent in multivariable analysis (P < .001). Patients who had bariatric surgery were also more likely to be older and have obesity, medical co-morbidities, fetal growth restriction, preterm birth, and cesarean delivery compared with those without bariatric surgery (all, P < .05). In a propensity score matched model, patients who had bariatric surgery were more likely to receive blood product transfusion (2.3% versus 1.6%; odds ratio = 1.45; 95% confidence interval, 1.19-1.77), but severe maternal morbidity other than blood product transfusion was comparable to those without (1.1% versus 1.4%; odds ratio = .80; 95% confidence interval, .63-1.02). CONCLUSION There is a gradual increase of pregnancy after bariatric surgery in recent years in the United States.

Midwifery 2023; 121:103652. [PMID: 36931137 DOI: 10.1016/j.midw.2023.103652] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 08/30/2022] [Accepted: 02/28/2023] [Indexed: 03/07/2023]
Abstract
BACKGROUND Obesity is known to negatively impact fertility and increase pregnancy related complications. Many women of childbearing age opt for bariatric surgery to lose weight in the preconception period. Physiological changes of bariatric surgery are associated with both benefits and risks for maternal and neonatal outcomes. How women understand these risks and experience pregnancy following bariatric surgery are largely unknown. OBJECTIVE To explore the information needs and experiences of Australian women who become pregnant following bariatric surgery. DESIGN An interpretive descriptive qualitative study of 11 Australian women with experiences of pregnancy following bariatric surgery participated in a private Facebook discussion group conducted in 2021. Women were recruited via targeted advertisements on social media. RESULTS Women identified several information gaps regarding the implications of having bariatric surgery for preconception, pregnancy, and postnatal periods. Family planning, pregnancy nutrition, and breastfeeding advice were key areas of information need. Women's experiences of pregnancy following bariatric surgery included attitudes of judgement and lack of knowledge from their healthcare providers. CONCLUSIONS Healthcare professionals caring for women who have had bariatric procedures need to ensure that all women are fully informed about the risks of becoming pregnant within the first 12-months post-surgery. They should also anticipate that despite recommendations, women will become pregnant earlier than advised, and can benefit from non-judgemental and supportive care to ensure risks of poor outcomes are minimised. The findings highlight that the provision of tailored resources and education for women and their healthcare teams are needed.

Arch Gynecol Obstet 2023; 307:343-378.

Abstract
PURPOSE Bariatric surgery increases the risk of lower birth weight, small-for-gestational-age (SGA) infants, and preterm birth in a subsequent pregnancy. However, the factors that contribute to these adverse birth outcomes are unclear. This review aimed to collate available information about risk factors of lower birth weight, SGA, and preterm birth following bariatric surgery. METHODS A literature search was conducted using five databases (PubMed, PsycINFO, EMBASE, Web of Science, and Cochrane Library) to obtain relevant studies. RESULTS A total number of 85 studies were included. Studies generally excluded surgery-to-conception interval, pregnancy complications, cigarette use, and maternal age as influencing factors of birth weight, SGA, or preterm birth. In contrast, most studies found that malabsorptive procedures, lower gestational weight gain, lower glucose levels, abdominal pain, and insufficient prenatal care were associated with an elevated risk of adverse birth outcomes. Findings were mixed regarding the effects of surgery-to-conception weight loss, pre-pregnancy body mass index, micronutrient deficiency, and lipid levels on birth outcomes. The examination of maternal microbiome profiles, placental function, alcohol use, and exercise was limited to one study; therefore, no conclusions could be made. CONCLUSION This review identified factors that appear to be associated (e.g., surgery type) or not associated (e.g., surgery-to-conception interval) with birth outcomes following bariatric surgery. The mixed findings and the limited number of studies on several variables (e.g., micronutrients, exercise) highlight the need for further investigation. Additionally, future studies may benefit from exploring interactions among risk factors and expanding to assess additional exposures such as maternal mental health.

Abstract
INTRODUCTION Bariatric surgery (BS) is known to reduce several obesity-related complications during pregnancy, but there is concern that it may increase the risk of maternal-fetal morbidity because of the malabsorption. This study aimed to investigate the impact of restrictive BS on several pregnancy outcomes in comparison with different grades of obesity. MATERIALS AND METHODS A single-center retrospective case-control study. All primiparous singleton pregnant women who underwent BS between the previous 1-5 years or with body mass index (BMI) ≥ 30 kg/m2 delivering in our center were included. Obstetric and perinatal outcomes were analyzed and compared between the two groups. RESULTS Overall, 90 women were included: 30 underwent BS and 60 were obese. The mean pre-pregnancy BMI was 31.0 ± 4.2 kg/m2 in the BS group and 38.1 ± 4.3 kg/m2 in the control group (p < 0.001). The obese group experienced higher rate of fetal macrosomia (25% vs 6.7%; p = 0.049), gestational hypertension (23.3% vs 3.3%; p = 0.04), preeclampsia (23.3% vs 0%; p = 0.04), gestational diabetes (33.3% vs 6.7%; p = 0.01), and cesarean section (68.3% vs 20%; p < 0.0001). The BS group showed higher frequency of small for gestational age (SGA) (46.7% vs 18.3%; p = 0.006), late preterm delivery (PTD) (33.3% vs 10%; p = 0.009), cholestasis (13.3% vs 1.7%; p = 0.049). Breastfeeding ≥ 6 months was higher among BS mothers (36.7% vs 11.7%; p = 0.007). CONCLUSIONS Our findings support the positive impact of BS on several obstetric outcomes, at the expense of a higher frequency of SGA and PTD. BS mothers more frequently achieved the recommended goal of breastfeeding for 6 months compared to obese women.

The Impact of Preconception Gastric Bypass Surgery on Maternal Micronutrient Status before and during Pregnancy: A Retrospective Cohort Study in the Netherlands between 2009 and 2019. Nutrients 2022; 14:nu14040736. [PMID: 35215386 PMCID: PMC8876006 DOI: 10.3390/nu14040736] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Revised: 01/28/2022] [Accepted: 02/03/2022] [Indexed: 12/15/2022] Open
Abstract
Post-bariatric weight loss can cause iatrogenic malnutrition and micronutrient depletion. In this study, we evaluated the impact of gastric bypass surgery (GB) and multivitamin supplement use on maternal micronutrient status before and across pregnancy. A retrospective medical chart review of 197 singleton pregnancies after GB with a due date between 2009 and 2019 was performed at a bariatric expertise center in the Netherlands. Hemoglobin, calcium, iron status, folate, vitamin D, vitamin B12 and ferritin levels were determined before and after GB during standard follow-up and at all gestational trimesters and analyzed using linear mixed models. Patients were prescribed standard multivitamin supplements or multivitamins specifically developed for post-bariatric patients (FitForMe WLS Forte (FFM)). Overall, hemoglobin and calcium levels decreased after surgery and during pregnancy, whereas folate, vitamin D, and vitamin B12 levels increased, and iron levels remained stable. FFM use was associated with higher hemoglobin, folate, vitamin D, and ferritin levels. In conclusion, through adequate supplementation and follow-up, GB does not have to result in impaired micronutrient status. Supplements developed specifically for post-bariatric patients generally result in higher micronutrient values than regular multivitamins before and during pregnancy. These data emphasize the urgent need for nutritional counseling including dietary and multivitamin supplement advise for post-bariatric women contemplating and during pregnancy.

Abstract
Pregnancy after bariatric surgery is usually considered safe. Recently, a few studies reported that bariatric surgery represents a risk factor for birth defects. A case series of six patients, born from women who had undergone biliopancreatic diversion, is reported. The clinical pattern was characterized by psychomotor development delay (100%), microphthalmia (83%), growth retardation (66%), hearing loss (66%), and variable facial dysmorphism. Based on the clinical profile and symptoms reported by women during pregnancy, a causal association between maternal chronic post-surgical malabsorption, congenital anomalies, and neonatal outcome is proposed, with vitamin A deficiency representing a major causing factor. Educational follow-up support, continuous clinical monitoring, and appropriate nutritional assessment appear to be crucial to reduce the potential risk of congenital malformations and child disability.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E2734.

Abstract
This systematic literature review aims to point out sex-specific special features that are important in the bariatric treatment of women suffering from severe obesity. A systematic literature search was carried out according to Cochrane and Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) guidelines. After the literature selection, the following categories were determined: sexuality and sexual function; contraception; fertility; sex hormones and polycystic ovary syndrome; menopause and osteoporosis; pregnancy and breastfeeding; pelvic floor disorders and urinary incontinence; female-specific cancer; and metabolism, outcome, and quality of life. For each category, the current status of research is illuminated and implications for bariatric treatment are determined. A summary that includes key messages is given for each subsection. An overall result of this paper is an understanding that sex-specific risks that follow or result from bariatric surgery should be considered more in aftercare. In order to increase the evidence, further research focusing on sex-specific differences in the outcome of bariatric surgery and promising treatment approaches to female-specific diseases is needed. Nevertheless, bariatric surgery shows good potential in the treatment of sex-specific aspects for severely obese women that goes far beyond mere weight loss and reduction of metabolic risks.

Abstract
Optimising the diet and weight of women prior to and during pregnancy is of paramount importance to both maternal and offspring health. In women who become pregnant after bariatric surgery, evidence suggests a better overall obstetric outcome in comparison to women with severe obesity managed conservatively. Historically, most studies in this population group have monitored supplement adherence or serum concentrations of micronutrients, rather than dietary intake. The aim of this study was to synthesise current knowledge of the dietary intake of women during pregnancy following bariatric surgery. A systematic search of search engines was conducted using the following databases: MEDLINE, Embase, CINAHL, Cochrane database, Scopus, Trip, NHS Evidence, UK Clinical Trials, ClinicalTrials.gov, Prospero, Epistemonikos and Open Grey. Titles and abstracts were screened independently by two reviewers against predefined inclusion and exclusion criteria. After removal of duplicates, 1594 titles were identified, of which 1586 were initially excluded. Following full-text review, four articles were included. In total, across all four studies, data from only 202 bariatric surgery participants were included, the majority of whom had had one type of surgery. Just one study included a control group. Reporting of nutritional outcomes was heterogenous, with none of the studies including complete macro and micronutrient intake results in their articles. An insufficient intake of protein was noted as a concern in two studies and associated with poor fetal growth in one study. Overall, this review has identified a paucity of data about the dietary intake of women during pregnancy after bariatric surgery.
