Comparing sexual self-concept in women with obesity pre- and post-bariatric surgery.

BACKGROUND: Obesity leads to increased disease burden, decreased life expectancy, and disrupted sexual life. One of the most effective ways of obesity treatment is bariatric surgery. This study was conducted aiming to determine and compare sexual self-concept in women with obesity pre- and post-bariatric surgery. METHOD: A longitudinal study comparing sexual self-concept pre and post- surgery was conducted on women with obesity referring to obesity clinics in the city of Tehran in 2020-2021. Data collection was performed using Snell's Multidimensional Sexual Self-Concept Questionnaire (MSSCQ), which was completed online. Data were analyzed using SPSS version 16 statistical software and Fisher's exact test, chi-square, Mann-Whitney, independent t, and logistic and linear regression tests. A p-value of less than 0.05 was considered significant. RESULTS: According to the findings, the mean (standard deviation) score of sexual self-concept was 240.26 (26.82) in the post-surgery group and 200.26 (32.24) in the pre-surgery group (P = 0.001), and the highest mean (standard deviation) score of sexual self-concept both in the pre-surgery group (13.06 [4.00]) and in the post-surgery group (15.46 [2.16]) was related to the area of sexual depression (P = 0.05). Also, with increasing educational level, the odds of bariatric surgery increased by 33%, and those who had no private bedroom had lower odds of bariatric surgery by 65%. In those who did not have other individuals living in their house and their spouse was not a smoker, the self-concept score was 52.35 and 23.11 units higher. CONCLUSION: In general, bariatric surgery can improve sexual self-care. Considering the issue of sexual self-concept in bariatric surgery, it is recommended to design appropriate counseling and planning before surgery according to the culture of each country.

Impact of Bariatric Surgery on metabolic health in a Uruguayan cohort and the emerging predictive role of FSTL1.

Obesity poses significant challenges, necessitating comprehensive strategies for effective intervention. Bariatric Surgery (BS) has emerged as a crucial therapeutic approach, demonstrating success in weight loss and comorbidity improvement. This study aimed to evaluate the outcomes of BS in a cohort of 48 Uruguayan patients and investigate the interplay between BS and clinical and metabolic features, with a specific focus on FSTL1, an emerging biomarker associated with obesity and inflammation. We quantitatively analyzed BS outcomes and constructed linear models to identify variables impacting BS success. The study revealed the effectiveness of BS in improving metabolic and clinical parameters. Importantly, variables correlating with BS success were identified, with higher pre-surgical FSTL1 levels associated with an increased effect of BS on BMI reduction. FSTL1 levels were measured from patient plasma using an ELISA kit pre-surgery and six months after. This research, despite limitations of a small sample size and limited follow-up time, contributes valuable insights into understanding and predicting the success of BS, highlighting the potential role of FSTL1 as a useful biomarker in obesity.

Effect of body mass index on 30-day complication rate and implant survival rate after simultaneous bilateral unicompartmental knee arthroplasty: a multicentre retrospective study.

OBJECTIVE: The practice of simultaneous bilateral unicompartmental knee arthroplasty (SBUKA) remains a topic of debate, particularly in patients with obesity. Thus, the purpose of this study was to assess the impact of body mass index (BMI) on the 30-day complication rate and the survival rate of the implant following SBUKA. METHODS: We retrospectively examined the clinical records of 245 patients (490 knees) who underwent SBUKA at the Affiliated Hospital of Qingdao University and the Third Hospital of Hebei Medical University between January 2010 and December 2020. Patients were categorised based on their BMI at the time of surgery into four groups: normal weight (BMI 18.5 to 22.9 kg/m2), overweight (BMI 23.0 to 24.9 kg/m2), obese (BMI 25.0 to 29.9 kg/m2), and severely obese (BMI ≥30 kg/m2). Variables such as length of hospital stay, duration of surgery, and costs of hospitalisation were compared across all groups. Additionally, we recorded the 30-day postoperative complication rate and the time from surgery to any required revision. The Kaplan-Meier survival analysis was employed to evaluate and compare the implant survival rates. RESULTS: The follow-up period for the 245 patients ranged from 39 to 114 months, with an average of 77.05±18.71 months. The incidence of complications within 30 days post-surgery did not significantly differ across the groups (χ2 = 1.102, p = 0.777). The implant survival rates from the lowest to the highest BMI groups were 97.14%, 93.9%, 94.44%, and 96.43%, respectively. Both the rate of implant revision (χ2 =1.612, p = 0.657) and the survival curves of the implants (p = 0.639) showed no statistically significant differences among the groups. CONCLUSIONS: BMI did not influence the 30-day complication rate nor the survival rate of implants following SBUKA, suggesting that SBUKA should not be contraindicated based on BMI alone.

Elements of Weight Management Among Pre-Kidney Transplant Candidates: The Patient Perspective.

Obesity and related comorbidities heighten risks for complications in kidney transplant settings. While pre-transplant patients often have access to nutrition counseling and health support, literature is limited on patients' perceptions of weight and motivation to lose weight prior to transplantation. We conducted a survey among ≥18-year-old patients on the kidney transplant waitlist at a single center. Questions addressed weight perception, motivation for weight loss, available resources, and engagement in physical activity. Medical records provided demographic and clinical data. Statistical tests analyzed quantitative data, while free-text responses were thematically grouped and described. Of 1055 patients, 291 responded and were matched with demographic data. Perceived weight changes correlated with actual changes in body mass index (BMI) (<24.9) were more receptive to weight center resources (<30 kg/m2) are most interested in weight loss resources and demonstrate motivation. Furthermore, pre-transplant nutrition counseling correlates with healthier behaviors. Integrating patients' perspectives enhances pre-transplant protocols by encouraging active involvement in health decisions.

Body mass index and pulmonary vein isolation: real-world data on outcomes and quality of life.

AIMS: Increasing numbers of overweight and obese patients undergo pulmonary vein isolation (PVI), despite the association between higher body mass index (BMI) and adverse PVI outcomes. Evidence on complications and quality of life in different bodyweight groups is limited. This study aims to clarify the impact of BMI on repeat ablations, periprocedural complications, and changes in quality of life. METHODS AND RESULTS: This multi-centre study analysed prospectively collected data from 15 ablation centres, covering all first-time PVI patients in the Netherlands from 2015 to 2021. Patients were categorized by BMI: normal weight (18.5-24.9 kg/m2), overweight (25-29.9 kg/m2), and obesity (≥30 kg/m2). Quality of life was assessed using the Atrial Fibrillation Effect on QualiTy-of-life questionnaire at baseline and 1-year post-PVI. Among 20 725 patients, 30% were of normal weight, 47% overweight, and 23% obese. Within the first year after PVI, obese patients had a higher incidence of repeat ablations than normal-weighing and overweight patients (17.8 vs. 15.6 and 16.1%, P < 0.05). Obesity was independently associated with repeat ablations (odds ratio 1.15; 95% confidence interval 1.01-1.31, P = 0.03). This association remained apparent after 3 years. Complication rates were 3.8% in normal weight, 3.0% in overweight, and 4.6% in obese, with weight class not being an independent predictor. Quality of life improved in all weight groups post-PVI but remained lowest in obese patients. CONCLUSION: Obesity is independently associated with a higher rate of repeat ablations. Pulmonary vein isolation is equally safe in all weight classes. Despite lower quality of life among obese individuals, substantial improvements occur for all weight groups after PVI.

The long-term effect of bariatric/metabolic surgery versus pharmacologic therapy in type 2 diabetes mellitus patients: A systematic review and meta-analysis.

Metabolic/bariatric surgery as a treatment for obesity and related diseases, such as type 2 diabetes mellitus (T2DM), has been increasingly recognised in recent years. However, compared with conventional pharmacologic therapy, the long-term effect (≥ 5 years) of metabolic surgery in T2DM patients is still unclear. This study aimed to evaluate the diabetes remission rate, incidence of diabetic microvascular complications, incidence of macrovascular complications, and mortality in T2DM patients who received metabolic surgery versus pharmacologic therapy more than 5 years after the surgery. Searching the database, including PubMed, Embase, Web of Science, and Cochrane Library from the inception to recent (2024), for randomised clinical trials (RCTs) or cohort studies comparing T2DM patients treated with metabolic surgery versus pharmacologic therapy reporting on the outcomes of the diabetes remission rate, diabetic microvascular complications, macrovascular complications, or mortality over 5 years or more. A total of 15 articles with a total of 85,473 patients with T2DM were eligible for review and meta-analysis in this study. There is a significant long-term increase in diabetes remission for metabolic surgery compared with conventional medical therapy in the overall pooled estimation and RCT studies or cohort studies separately (overall: OR = 4.58, 95% CI: 1.89-11.07, P < 0.001). Significant long-term decreases were found in the pooled results of microvascular complications incidence (HR = 0.57, 95% CI: 0.41-0.78, P < 0.001), macrovascular complications incidence (HR = 0.59, 95% CI: 0.50-0.70, P < 0.001) and mortality (HR = 0.53, 95% CI: 0.53-0.79, P = 0.0018). Metabolic surgery showed more significant long-term effects than pharmacologic therapy on diabetes remission, macrovascular complications, microvascular complications incidence, and all-cause mortality in patients with T2DM using currently available evidence. More high-quality evidence is needed to validate the long-term effects of metabolic surgery versus conventional treatment in diabetes management.

Cortisol secretion autonomy associated with weight loss outcome after laparoscopic sleeve gastrectomy: a prospective cohort study in Asian patients.

OBJECTIVE: Laparoscopic sleeve gastrectomy (LSG) is a widely recognized effective bariatric surgery. However, variable weight loss outcomes post-surgery remained a clinical challenge. Currently, there is no established consensus on the factors influencing weight loss failure following LSG. This study aimed to explore the association between preoperative cortisol secretion autonomy and postoperative weight loss in obese patients undergoing LSG. PATIENTS AND METHODS: A cohort of 181 patients with simple obesity (BMI ≥ 28 kg/m2) who underwent LSG and were followed up for one year was analyzed. Weight loss was measured by the percentage of excess weight loss (%EWL), and cortisol secretion autonomy was evaluated using a 1 mg dexamethasone suppression test (DST). Regression models were used to analyze the correlation between preoperative 1 mg DST results and %EWL one year after laparoscopic sleeve gastrectomy (LSG). RESULTS: Cortisol secretion autonomy was significantly lower in the %EWL ≥ 75% group and higher in the %EWL < 75% group, showing a negative correlation with %EWL (R = -0.336, p = 0.001). Logistic regression analysis indicated that high cortisol secretion autonomy was significantly correlated with %EWL < 75% after LSG. The likelihood of %EWL being < 75% was 10.47 times greater in patients with high cortisol secretion autonomy compared to those with low cortisol secretion autonomy (odds ratio 10.472, confidence interval: 1.660-66.048, p = 0.012). CONCLUSIONS: Cortisol secretion autonomy emerges as an independent predictor of weight loss outcomes in Asian patients undergoing LSG. This finding suggests the potential for cortisol secretion autonomy to inform preoperative assessments and personalized treatment strategies in bariatric surgery.

Comprehensive assessment of body mass index effects on short-term and long-term outcomes in laparoscopic gastrectomy for gastric cancer: a retrospective study.

To examine the influence of Body Mass Index (BMI) on laparoscopic gastrectomy (LG) short-term and long-term outcomes for gastric cancer. A retrospective analysis was conducted on gastric cancer patients undergoing LG at the Third Hospital of Nanchang City from January 2013 to January 2022. Based on WHO BMI standards, patients were categorized into normal weight, overweight, and obese groups. Factors such as operative time, intraoperative blood loss, postoperative complications, and overall survival were assessed. Across different BMI groups, it was found that an increase in BMI was associated with longer operative times (average times: 206.22 min for normal weight, 231.32 min for overweight, and 246.78 min for obese), with no significant differences noted in intraoperative blood loss, postoperative complications, or long-term survival among the groups. The impact of BMI on long-term survival following LG for gastric cancer was found to be insignificant, with no notable differences in survival outcome between different BMI groups. Although higher BMI is associated with increased operative time in LG for gastric cancer, it does not significantly affect intraoperative blood loss, postoperative complications, recovery, or long-term survival. LG is a feasible treatment choice for obese patients with gastric cancer.

How does bariatric surgery remodel adipose tissue?

This lecture delves into the pivotal role of adipose tissue in obesity and its response to weight loss, particularly via bariatric surgery. Adipose tissue, responsible for storing excess energy, undergoes significant changes during obesity, marked by inflammation and fibrosis. Bariatric surgery, serving as a model, allow the exploration of adipose tissue remodeling post-weight loss, inducing metabolic and fibro-inflammatory shifts. Despite successful weight loss, inflammation and fibrosis persist, as evidenced by changes in immune cells, altered cytokine profiles and the accumulation of extracellular matrix (ECM). Unfortunately, these lingering effects impair the normal adipose tissue function. In this context, adipose progenitors, an heterogenous resident population of mesenchymal stromal cells, display functions important to fibrosis development, capable of differentiating into myofibroblasts and contributing to ECM deposition. Particularly, a distinct subpopulation of adipose progenitors with high CD9 expression (CD9high) is associated with fibrosis and insulin resistance in human obesity. The persistence of fibrosis post-weight loss poses challenges, correlating with metabolic dysfunction despite improved glucose tolerance. A comprehensive understanding of the mechanisms driving adipose tissue remodeling and fibrosis post-weight loss is imperative for the development of effective treatments for obesity. The intricate interplay between adipose tissue, inflammation, and fibrosis underscores the necessity for further in-depth research to elucidate these mechanisms and formulate targeted therapies for obesity-related complications.

Comparison of perioperative outcomes between robot-assisted partial nephrectomy and laparoscopic partial nephrectomy in obese patients.

OBJECTIVE: The primary surgical techniques used to treat localized renal tumors are laparoscopic partial nephrectomy (LPN) and robot-assisted partial nephrectomy (RAPN). Obese patients have more intra-abdominal fat accumulation, which may make the localization and operation in minimally invasive surgery more complicated. Currently, limited research has been conducted on which method is more suitable for performing a partial nephrectomy on obese individuals. The aim of our investigation was to analyze and compare the perioperative results associated with both approaches to offer valuable information about the selection of LPN or RAPN as an optimal choice when performing a partial nephrectomy in obese patients. PATIENTS AND METHODS: We retrospectively collected clinical data from 78 cases of obese individuals [Body mass index (BMI) > 28] who underwent RAPN, as well as 50 cases of obese individuals (BMI > 28) who underwent LPN. The analysis covered various aspects, including initial patient characteristics, glomerular filtration rate (GFR), warm ischemia time (WIT), operation time, volume of blood loss during the surgical procedure, time taken to recover bowel function, positive surgical margin rate, incidence of postoperative complications, and postoperative hospital stay. RESULTS: We observed that RAPNs exhibited shorter warm ischemia time and reduced intraoperative blood loss in obese patients, along with decreased postoperative duration of abdominal drainage and hospitalization periods compared to LPNs. CONCLUSIONS: In obese patients, RAPN demonstrates advantages over LPN in minimizing intraoperative blood loss, WIT, and facilitating postoperative recovery. These findings may serve as valuable evidence when considering the choice between LPN or RAPN for partial nephrectomy in obese individuals.

Does obesity and varying body mass index affect the clinical outcomes and safety of biportal endoscopic lumbar decompression? A comparative cohort study.

BACKGROUND: Endoscopic spine surgery has recently grown in popularity due to the potential benefits of reduced pain and faster recovery time as compared to open surgery. Biportal spinal endoscopy has been successfully applied to lumbar disc herniations and lumbar spinal stenosis. Obesity is associated with increased risk of complications in spine surgery. Few prior studies have investigated the impact of obesity and associated medical comorbidities with biportal spinal endoscopy. METHODS: This study was a prospectively collected, retrospectively analyzed comparative cohort design. Patients were divided into cohorts of normal body weight (Bone Mass Index (BMI)18.0-24.9), overweight (BMI 25.0-29.9) and obese (BMI > 30.0) as defined by the World Health Organization (WHO). Patients underwent biportal spinal endoscopy by a single surgeon at a single institution for treatment of lumbar disc herniations and lumbar spinal stenosis. Demographic data, surgical complications, and patient-reported outcomes were analyzed. Statistics were calculated amongst treatment groups using analysis of variance and chi square where appropriate. Statistical significance was determined as p < 0.05. RESULTS: Eighty-four patients were followed. 26 (30.1%) were normal BMI, 35 (41.7%) were overweight and 23 (27.4%) were obese. Patients with increasing BMI had correspondingly greater American Society of Anesthesiologist (ASA) scores. There were no significant differences in VAS Back, VAS Leg, and ODI scores, or postoperative complications among the cohorts. There were no cases of surgical site infections in the cohort. All cohorts demonstrated significant improvement up to 1 year postoperatively. CONCLUSIONS: This study demonstrates that obesity is not a risk factor for increased perioperative complications with biportal spinal endoscopy and has similar clinical outcomes and safety profile as compared to patients with normal BMI. Biportal spinal endoscopy is a promising alternative to traditional techniques to treat common lumbar pathology.

Analysis of correlation between BMI and TWL% outcome following metabolic and bariatric surgery: a retrospective study using restricted cubic spline.

OBJECTIVE: This study aimed to examine the correlation between preoperative body mass index (BMI) and adequate percentage of total weight loss (TWL%) outcome and present evidence of tiered treatment for patients with obesity in different preoperative BMI. METHODS: We included patients with complete follow-up data who underwent metabolic and bariatric surgery (BMS). We termed optimal clinical response as TWL% >20% at one year following MBS. To investigate dose-response association between preoperative BMI and optimal clinical response, preoperative BMI was analyzed in three ways: (1) as quartiles; (2) per 2.5 kg/m2 units (3) using RCS, with 3 knots as recommended. RESULTS: A total of 291 patients with obesity were included in our study. The corresponding quartile odds ratios associated with optimal clinical response and adjusted for potential confounders were 1.00 (reference), 1.434 [95% confidence interval (95%CI)   =  0.589-3.495], 4.926 (95%CI   =  1.538-15.772), and 2.084 (95%CI   =  0.941-1.005), respectively. RCS analysis showed a non-linear inverted U-shaped association between preoperative BMI and optimal clinical response (Nonlinear P   =  0.009). In spline analysis, when preoperative BMI was no less than 42.9 kg/m2, the possibility of optimal clinical response raised as preoperative BMI increased. When preoperative BMI was greater than 42.9 kg/m2, the possibility of optimal clinical response had a tendency to decline as preoperative BMI increased. CONCLUSION: Our research indicated the non-linear inverted U-shaped correlation between preoperative BMI and adequate weight loss. Setting a preoperative BMI threshold of 42.9 is critical to predicting optimal clinical outcomes.

Recommendations for eligibility criteria concerning bariatric and metabolic surgical and endoscopic procedures for obese Hong Kong adults 2024: Hong Kong Society for Metabolic and Bariatric Surgery Position Statement.

The surgical management of obesity in Hong Kong has rapidly evolved over the past 20 years. Despite increasing public awareness and demand concerning bariatric and metabolic surgery, service models generally are not standardised across bariatric practitioners. Therefore, a working group was commissioned by the Hong Kong Society for Metabolic and Bariatric Surgery to review relevant literature and provide recommendations concerning eligibility criteria for bariatric and metabolic interventions within the local population in Hong Kong. The current position statement aims to provide updated guidance regarding the indications and contraindications for bariatric surgery, metabolic surgery, and bariatric endoscopic procedures.

Association of parental obesity with the profile of metabolic-bariatric surgery patients: a cohort study of the German StuDoQ|MBE registry.

OBJECTIVES: To investigate the association of parental obesity (PO) with onset of obesity, pre-surgical disease duration and body mass index (BMI) at the time of surgery in patients undergoing metabolic-bariatric surgery (MBS). DESIGN: This is a cohort study of the German StuDoQ registry for metabolic-bariatric diseases. All surgical cases from initiation of the registry in September 2015 until August 2020 were screened for pertinent information. SETTING: The registry is based on participating German hospitals of various sizes. PARTICIPANTS: A total of 11 891 patients were included in this analysis, 74.2% of which were females and 25.8% males. Roux-en-Y gastric bypass was performed in 5652 (47.5%) cases, sleeve gastrectomy in 4618 (38.8%) cases and one-anastomosis gastric bypass in 1621 (13.6%) cases. RESULTS: One-sided and two-sided PO are independently associated with early-onset obesity (OR 1.61, [95% CI, 1.47 to 1.76], p<0.001 and OR 2.45, [95% CI, 2.22 to 2.71], p<0.001) and prolonged pre-surgical disease duration (regression coefficient 2.39, [95% CI, 1.93 to 2.83], p<0.001 and regression coefficient 4.27, [95% CI, 3.80 to 4.75], p<0.001). Unlike one-sided PO, two-sided PO had a significant association with BMI at the time of surgery (regression coefficient 0.49, [95% CI, 0.14 to 0.85], p=0.006). Age at the onset of obesity and disease duration had a negative association with BMI at the time of surgery (regression coefficient -0.13, [95% CI, -0.14 to -0.11], p<0.001 and regression coefficient -0.05, [95% CI, -0.07 to -0.04], p<0.001). CONCLUSIONS: This study established a clear association between PO status of patients undergoing MBS and their pre-surgical patient profile as well as known risk factors for poor postoperative response.

Updates in Medical and Surgical Weight Loss.

The number of individuals with obesity is at an all-time high, and the rate of obesity continues to climb each year. Obesity is a chronic disease with widespread effects throughout the body. Midwives and perinatal care providers need an understanding of the etiology, pathophysiology, and interventions for obesity. A review of evidence-based diet and lifestyle modifications, medications, and surgical procedures is presented.

[When should a patient with obesity be referred to endocrinology? Current indications for bariatric surgery]. / ¿Cuándo derivar a endocrinología el paciente con obesidad? Indicaciones actuales de la cirugía bariátrica.

Bariatric surgery (BS) has been shown to be effective and efficient, but only 1% of selected patients will ever receive it. Compared to medical treatment of obesity, BS has demonstrated greater long-term sustained weight loss, a reduction in both total and cardiovascular (CV) mortality, improvement or remission of CV risk factors and other comorbidities associated with obesity, as well as improved mobility and quality of life. BS presents similar risks to other abdominal surgeries, with obesity as an added risk factor. However, mortality after this type of surgery is less than 1%, being in specialised centres even lower than 0.3%, with a morbidity of less than 7%. The most commonly performed surgical procedures at present are vertical gastrectomy and Roux---Y gastric bypass, preferably by laparoscopic approach.

Bariatric surgery for spontaneous ovulation in women living with polycystic ovary syndrome: the BAMBINI multicentre, open-label, randomised controlled trial.

BACKGROUND: Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. Obesity exacerbates the reproductive complications of PCOS; however, the management of obesity in women with PCOS remains a large unmet clinical need. Observational studies have indicated that bariatric surgery could improve the rates of ovulatory cycles and prospects of fertility; however, the efficacy of surgery on ovulation rates has not yet been compared with behavioural modifications and medical therapy in a randomised trial. The aim of this study was to compare the safety and efficacy of bariatric surgery versus medical care on ovulation rates in women with PCOS, obesity, and oligomenorrhoea or amenorrhoea. METHODS: In this multicentre, open-label, randomised controlled trial, 80 women older than 18 years, with a diagnosis of PCOS based on the 2018 international evidence-based guidelines for assessing and managing PCOS, and a BMI of 35 kg/m2 or higher, were recruited from two specialist obesity management centres and via social media. Participants were randomly assigned at a 1:1 ratio to either vertical sleeve gastrectomy or behavioural interventions and medical therapy using a computer-generated random sequence (PLAN procedure in SAS) by an independent researcher not involved with any other aspect of the clinical trial. The median age of the entire cohort was 31 years and 79% of participants were White. The primary outcome was the number of biochemically confirmed ovulatory events over 52 weeks, and was assessed using weekly serum progesterone measurements. The primary endpoint included the intention-to-treat population and safety analyses were per-protocol population. This study is registered with the ISRCTN registry (ISRCTN16668711). FINDINGS: Participants were recruited from Feb 20, 2020 to Feb 1, 2021. 40 participants were assigned to each group and there were seven dropouts in the medical group and ten dropouts in the surgical group. The median number of ovulations was 6 (IQR 3·5-10·0) in the surgical group and 2 (0·0-4·0) in the medical group. Women in the surgical group had 2.5 times more spontaneous ovulations compared with the medical group (incidence rate ratio 2·5 [95% CI 1·5-4·2], p<0·0007). There were more complications in the surgical group than the medical group, although without long-term sequelae. There were 24 (66·7%) adverse events in the surgical group and 12 (30·0%) in the medical group. There were no treatment-related deaths. INTERPRETATION: Bariatric surgery was more effective than medical care for the induction of spontaneous ovulation in women with PCOS, obesity, and oligomenorrhoea or amenorrhoea. Bariatric surgery could, therefore, enhance the prospects of spontaneous fertility in this group of women. FUNDING: The Jon Moulton Charity Trust.
