Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine condition in premenopausal women and is a common cause of anovulatory subfertility. Although obesity does not form part of the diagnostic criteria, it affects a significant proportion of women with PCOS and is strongly implicated in the pathophysiology of the disease. Both PCOS and obesity are known to impact fertility in women; obesity also reduces the success of assisted reproductive technology (ART). With or without pharmacotherapy, lifestyle intervention remains the first-line treatment in women with PCOS and obesity. Bariatric surgery is still an experimental treatment in women with PCOS and subfertility. This review will present an overview of the pathophysiology of PCOS and obesity and the role of bariatric surgery. Although data are sparse regarding the impact of bariatric surgery on subfertility in women with PCOS and obesity, existing studies point to a beneficial role in treating metabolic and reproductive dysfunction.

Abstract
PURPOSE Polycystic ovary syndrome (PCOS) is a complex genetic trait and the most common endocrine disorder of women, clinically evident in 5% to 15% of reproductive-aged women globally, with associated cardiometabolic dysfunction. Adipose tissue (AT) dysfunction appears to play an important role in the pathophysiology of PCOS even in patients who do not have excess adiposity. METHODS We undertook a systematic review concerning AT dysfunction in PCOS, and prioritized studies that assessed AT function directly. We also explored therapies that targeted AT dysfunction for the treatment of PCOS. RESULTS Various mechanisms of AT dysfunction in PCOS were identified including dysregulation in storage capacity, hypoxia, and hyperplasia; impaired adipogenesis; impaired insulin signaling and glucose transport; dysregulated lipolysis and nonesterified free fatty acids (NEFAs) kinetics; adipokine and cytokine dysregulation and subacute inflammation; epigenetic dysregulation; and mitochondrial dysfunction and endoplasmic reticulum and oxidative stress. Decreased glucose transporter-4 expression and content in adipocytes, leading to decreased insulin-mediated glucose transport in AT, was a consistent abnormality despite no alterations in insulin binding or in IRS/PI3K/Akt signaling. Adiponectin secretion in response to cytokines/chemokines is affected in PCOS compared to controls. Interestingly, epigenetic modulation via DNA methylation and microRNA regulation appears to be important mechanisms underlying AT dysfunction in PCOS. CONCLUSION AT dysfunction, more than AT distribution and excess adiposity, contributes to the metabolic and inflammation abnormalities of PCOS. Nonetheless, many studies provided contradictory, unclear, or limited data, highlighting the urgent need for additional research in this important field.

Obes Surg 2023; 33:2335-2341. [PMID: 37188894 DOI: 10.1007/s11695-023-06617-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 04/17/2023] [Accepted: 04/19/2023] [Indexed: 05/17/2023]
Abstract
PURPOSE This study aimed to evaluate the efficacy of sleeve gastrectomy (SG) on patients with obesity and polycystic ovary syndrome (PCOS). MATERIALS AND METHODS We searched PubMed, Embase, Cochrane Library, and Web of Science to identify relevant studies published prior to December 2, 2022. Meta-analysis was performed on menstrual irregularity, total testosterone, sex hormone-binding globulin (SHBG), anti-Mullerian hormone (AMH), glucolipid metabolism indicators, and body mass index (BMI) following SG. RESULTS Six studies and 218 patients were included in the meta-analysis. Following SG, menstrual irregularity significantly decreased (odds ratio [OR] 0.03; 95% confidence intervals [CIs], 0.00-0.24; P=0.001). Additionally, SG can lower total testosterone levels (MD -0.73; 95% CIs -0.86-0.60; P< 0.0001), as well as BMI (MD -11.59; 95% CIs -13.10-10.08; P<0.0001). A significant increase was observed in the levels of SHBG and high-density lipoprotein (HDL) after SG. In addition to reducing fasting blood glucose, insulin, triglycerides (TG), and low-density lipoprotein levels, SG significantly reduced low-density lipoprotein levels as well. CONCLUSIONS Following SG, we firstly demonstrated significant improvements in menstrual irregularity, testosterone and SHGB levels, glycolipid metabolism indicators, and BMI. Therefore, SG may be considered as a new option for the clinical treatment of patients with obesity and PCOS.

Abstract
UNLABELLED Polycystic ovary syndrome (PCOS) is a complicated reproductive endocrine disease that is closely related to obesity. Metabolic surgery ameliorates a series of clinical manifestations and related comorbidities of PCOS. However, the overall efficacy of metabolic surgery on PCOS remains uncertain. This systematic review and meta-analysis aimed to evaluate the therapeutic effects of metabolic surgery on obese patients with PCOS. A systematic literature search for relevant studies was conducted on PubMed, Embase, Web of Science, and the Cochrane Library from inception to June 2021. Data extraction and quality evaluation were performed by three researchers, and RevMan 5.4 software was used to conduct the meta-analysis. A total of 14 studies involving 501 obese patients with PCOS were included. Incidence of PCOS in obese women ranged from 5.5% to 63.5% among the included studies. The results showed the incidence of abnormal menstruation decreased from 81% to 15% (OR=0.03, 95% confidence interval (CI): 0.01-0.08), while the incidence of hirsutism dropped from 71% to 38% (OR=0.21, 95% CI: 0.06-0.74). Serum total testosterone and free testosterone levels decreased by 25.92 ng/dL (MD = -25.92, 95% CI: -28.90- -22.93) and 2.28 ng/dL (SMD = -2.28, 95% CI: -3.67- -0.89), respectively. Sex hormone-binding globulin (SHBG) levels increased by 26.46 nmol/L (MD = 26.46, 95% CI: 12.97-39.95). Serum anti-Mullerian hormone (AMH) levels decreased by 1.29 ng/mL (MD = -1.29, 95% CI: -1.92- -0.66). Small sample size studies revealed that pregnancy rates ranged from 95.2% to 100% postoperatively. Metabolic surgery contributed to marked improvement of abnormal menstruation, hirsutism, and levels of free testosterone, total testosterone, SHBG, and AMH in patients with PCOS. Our findings indicate that patients with PCOS are expected to benefit from metabolic surgery, and could help potentially improve their reproductive outcomes. Metabolic surgery could thus be a new viable option for the clinical treatment of PCOS. SYSTEMATIC REVIEW REGISTRATION PROSPERO https://www.crd.york.ac.uk/PROSPERO/, identifier CRD42021251524.

Abstract
AIMS To determine the health outcomes associated with weight loss in individuals with obesity, and to better understand the relationship between disease burden (disease burden; ie, prior comorbidities, healthcare utilization) and weight loss in individuals with obesity by analysing electronic health records (EHRs). MATERIALS AND METHODS We conducted a case-control study using deidentified EHR-derived information from 204 921 patients seen at the Cleveland Clinic between 2000 and 2018. Patients were aged ≥20 years with body mass index ≥30 kg/m2 and had ≥7 weight measurements, over ≥3 years. Thirty outcomes were investigated, including chronic and acute diseases, as well as psychological and metabolic disorders. Weight change was investigated 3, 5 and 10 years prior to an event. RESULTS Weight loss was associated with reduced incidence of many outcomes (eg, type 2 diabetes, nonalcoholic steatohepatitis/nonalcoholic fatty liver disease, obstructive sleep apnoea, hypertension; P < 0.05). Weight loss >10% was associated with increased incidence of certain outcomes including stroke and substance abuse. However, many outcomes that increased with weight loss were attenuated by disease burden adjustments. CONCLUSIONS This study provides the most comprehensive real-world evaluation of the health impacts of weight change to date. After comorbidity burden and healthcare utilization adjustments, weight loss was associated with an overall reduction in risk of many adverse outcomes.

Abstract
BACKGROUND Bariatric surgery is effective for polycystic ovary syndrome (PCOS), while the exact mechanism remains unclear. OBJECTIVES To assess the impact of bariatric surgery on PCOS patients and further explore the possible mechanism. SETTING A meta-analysis. METHODS We searched PubMed, Web of Science, The Cochrane Library, and Embase to identify relevant studies published before November 2020. RESULTS Twenty-one studies met our inclusion criteria, and we identified 552 patients with PCOS study. Results showed that the prevalence of preoperative PCOS, menstrual irregularity, hirsutism, type 2 diabetes (T2D), hypertension, infertility, and depression significantly decreased after bariatric surgery. Levels of total testosterone, fasting insulin, and luteinizing hormone (LH) decreased and estradiol increased, while levels of follicle-stimulating hormone (FSH) and LH/FSH did not show significant changes during the 3-month follow-up. There were decreases in testosterone and fasting insulin levels when the postoperative follow-up time was 6 months or ≥12 months. Levels of fasting blood glucose and triglycerides were significantly reduced after 6 months or ≥12 months of bariatric surgery. High-density lipoprotein (HDL) and sex hormone-binding globulin (SHBG) significantly improved ≥12 months after bariatric surgery. CONCLUSION Symptoms of PCOS and related complications are significantly alleviated after bariatric surgery. In addition, we found a significant improvement on anomalous secretion of gonadotropins, glucose metabolism, and lipid metabolism in patients with PCOS after bariatric surgery.

Abstract
Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in reproductive-age women that causes infertility. Obesity and insulin resistance are closely tied to the pathophysiology of PCOS. Current first-line treatments include lifestyle modifications, hormone modulators, and laparoscopic ovarian drilling, but little attention has been given to bariatric surgery as a viable option. A detailed review of the literature regarding the outcomes of obese women with PCOS after bariatric surgery is necessary. All studies were found in the PubMed database, limited to females and humans, and selected due to relevancy and quantitative data. Bariatric surgery promotes significant weight loss within one year, which is associated with amelioration of insulin resistance, hyperandrogenism, menstrual irregularity, and ovulatory dysfunction. Surgery successfully mediates the regression of PCOS and promotes successful pregnancy. Thus, we recommend the consideration of bariatric surgery as part of the main treatment considerations in obese patients with PCOS. However, more focused and comprehensive research with better study designs are still needed in the future to investigate PCOS and bariatric surgery.

Abstract
Background: Obesity is one of the most common risk factors for polycystic ovarian syndrome (PCOS). Reducing body weight has shown to improve the symptoms of PCOS; however, it is still unclear if the surgical treatment of obesity can have better outcomes to control obesity and improve PCOS. Objective: This study aims to identify the impact of sleeve gastrectomy on PCOS symptoms in Riyadh, Saudi Arabia with a comparison of other weight reduction surgeries. Design and Setting: This is a prospective study that included patients with PCOS who had weight reduction surgeries between 2018 and 2020, in Riyadh, Saudi Arabia. Using an online questionnaire, demographic data will be collected and information about menstruation, abortion, polycystic ovarian syndrome, and bariatric surgeries (if any). Data analysis was done through Statistical Package for the Social Sciences (SPSS) v26 (IBM Corp., Armonk, NY, USA). Results: Ninety-nine female patients responded to this survey, all of whom had PCOS; 57.6% of these patients had a positive family history of PCOS. The most-reported PCOS symptoms were irregular menses (63.6%) and weight gain (53.5%), while 9.1% were asymptomatic. 52.5% were obese, and 91.1% underwent gastric sleeve surgery to treat their obesity. 41.4% of the females had a regular cycle before the operation, which increased to 60.6% after the operation; 48.5% had a normal flow before the operation, which increased to 61.6% after the operation. 15.2% conceived once before the operation, which increased to 16.2% after the operation. 11.1% had one abortion before surgery, which decreased to 7.1% after surgery. 55.6% observed an improvement in their PCOS symptoms after surgery, and 47.5% found that their fertility improved according to their own perception. Females with a positive family history of PCOS had a higher prevalence of PCOS (p-value <0.001). Also, females 30-39 years old are significantly more likely to have PCOS (p-value <0.001). The incidence of abnormal menstrual flow and irregular menstrual cycle was seen significantly more in PCOS patients than non-PCOS (p-value=0.019 and 0.004, respectively). PCOS symptoms and fertility significantly improved after surgery (p-value=0.031 and 0.043, respectively). Conclusion: Sleeve gastrectomy can lead to significant improvement in fertility and symptoms of PCOS. It can also reduce the incidence of abortion. Other surgical techniques should be investigated.

Abstract
BACKGROUND Observational studies have shown a link between elevated body mass index (BMI) and the risk of polycystic ovary syndrome (PCOS). While Mendelian randomization (MR) studies in Europeans have suggested a causal role of increased BMI in PCOS, whether the same role is suggested in Asians has yet to be investigated. We used MR studies to infer causal effects using genetic data from East Asian populations. METHODS AND FINDINGS We performed a 2-sample bidirectional MR analysis using summary statistics from genome-wide association studies (GWAS) of BMI (with up to 173 430 individuals) and PCOS (4386 cases and 8017 controls) in East Asian populations. Seventy-eight single nucleotide polymorphisms (SNPs) correlated with BMI were selected as genetic instrumental variables to estimate the causal effect of BMI on PCOS using the inverse-variance weighted (IVW) method. To test the reliability of the results, further sensitivity analyses included MR-Egger regression, weighted median estimates, and leave-one-out analysis. The IVW analysis indicated a significant association between high BMI and the risk of PCOS (odds ratio per standard deviation higher BMI, 2.208; 95% confidence interval 1.537 to 3.168, P = 1.77 × 10-5). In contrast, the genetic risk of PCOS had no significant effect on BMI. CONCLUSIONS The results of our bidirectional MR study showed that an increase in BMI causes PCOS, while PCOS does not cause an increased BMI. This study provides further genetic support for a link between BMI and PCOS. Further research is needed to interpret the potential mechanisms of this association.

Abstract
PURPOSE Conditions associated with surgical technique and postoperative lifestyle changes, as well as the characteristics of patients, may affect weight loss following laparoscopic sleeve gastrectomy. In this study, the effects of age, gender, BMI, and excess weight at the time of surgery on weight loss during follow-up were examined. MATERIALS AND METHODS Demographic data (age, gender), preoperative BMI, and weight values of the patients were recorded. TWL% and EWL% values of patients were recorded during follow-up at 1st, 3rd, 6th, 9th, 12th, and 18th months. Patients were grouped according to age (AGE1 < 30, AGE2 30-50, AGE3 ≥ 50 years), BMI at the time of surgery (BMI1 ≤ 50, BMI2 > 50 kg/m2), and EW at the time of surgery (EW1 ≤ 60, EW2 > 60 kg). EWL% values obtained in the follow-up visits were compared among the gender, age, BMI, and EW groups. RESULTS A total of 456 patients (371 females, 85 males) were operated. Mean EWL% was lower in AGE3 group (p < 0.001). Patients in AGE1 group had the highest mean EWL%, while those in BMI2 and EW2 groups had lower mean EWL% values throughout the follow-up period (p < 0.001). Regression analysis showed that age and BMI were associated with EWL% at all follow-up visits (p < 0.05). CONCLUSION Patients with less than 60 kg of excess weight, those with BMI ≤ 50 kg/m2 and younger patients may lose weight more effectively following LSG.

Abstract
Polycystic ovary syndrome (PCOS) is a common disease among the bariatric population. However, there are limited data regarding the impact of laparoscopic sleeve gastrectomy (SG) on these patients. The study was conducted at University Hospital, United States. The purpose of this study was to examine per cent excess body weight loss (%EWL) and diabetes control in patients who have PCOS compared with those without PCOS. A total of 550 female patients underwent SG between December 2011 and October 2016. Retrospective analysis was completed to include follow-up data at 1, 3, 6, and 12 months and yearly after that. Outcomes measured were %EWL and hemoglobin A1c (HgbA1c). The mean and median follow-up for the entire cohort was 21 and 15 months, respectively. Seventy-eight per cent of patients completed at least 12 months of follow-up for %EWL, although only 21 per cent had similar follow-up for HgbA1c. PCOS patients had similar age (36.3 vs 36.2 years, P = 0.90), preoperative BMI (47.2 vs 47.2, P = 0.99), preoperative HgbA1c (6% vs 5.8%, P = 0.31), conversion rate to gastric bypass, and other associated comorbidities compared with non-PCOS comparisons. There was no difference in %EWL at 12-month (49.7% vs 53.1%, P = 0.53) or 24-month (43% vs 49.8%, P = 0.46) postoperative intervals. There was no difference in absolute change of HgbA1c at 12 months (-0.47% vs -0.67%, P = 0.39). SG has equivalent short-term results in %EWL and reduction in HgbA1c for patients who have PCOS and those who do not.

Abstract
Polycystic ovary syndrome (PCOS) has multiple etiologies including ovarian and adrenal hyperandrogenism, neuro-endocrine and hypothalamic-pituitary dysfunction, and disorders of peripheral insulin resistance. Obesity is neither necessary nor sufficient for the PCOS phenotype, and the association of PCOS with obesity is not universal, with national, cultural, and ethnic differences. Obesity, particularly visceral adiposity which is common in obese and non-obese women with PCOS, amplifies and worsens all metabolic and reproductive outcomes in PCOS. Obesity increases insulin resistance and compensatory hyperinsulinemia, which in turn increases adipogenesis and decreases lipolysis. Obesity sensitizes thecal cells to LH stimulation and amplifies functional ovarian hyperandrogenism by upregulating ovarian androgen production. Obesity increases inflammatory adipokines which, in turn, increase insulin resistance and adipogenesis. Lifestyle interventions focused on diet-weight loss and concurrent exercise are central to therapy which also commonly subsequently needs to include pharmacologic therapy. PCOS symptoms commonly improve with 5% to 10% weight loss, but 25% to 50% weight loss, usually achievable only through bariatric surgery, may be required for morbid obesity unresponsive to lifestyle-medical treatment. Bariatric surgery is a valuable approach to weight loss in PCOS where BMI is ≥40 kg/m2 when non-surgical treatment and/or induction of pregnancy have failed, and can be an initial treatment when BMI is ≥50 kg/m2. Further research in PCOS is needed to better understand the fundamental basis of the disorder, to ameliorate obesity, to correct hyperandrogenism, ovulation, hyperinsulinemia, and to optimize metabolic homeostasis.
