nutrition and bariatric surgery

BACKGROUND: Bariatric surgery is a procedure for people with class II and III obesity who are unable to lose weight using traditional methods. The incidence rate of bariatric surgery in reproductive-age women is increasing rapidly, so the number of women who become pregnant after bariatric surgery is rising. AIM: To collate and synthesise available literature regarding breastfeeding following bariatric surgery. METHODS: This review was reported by the preferred reporting items for systematic reviews and meta-analysis extension for scoping reviews (PRISMA-Scr)...

Bariatric surgery is regularly offered to women of childbearing age. Pregnancy after such surgery should be planned and requires special attention. Some complications associated with obesity during pregnancy are reduced after bariatric surgery, but reduced dietary intake and malabsorption can cause nutritional deficiencies, that need to be carefully screened for and supplemented. Dietary management is recommended, and any unusual abdominal pain should be referred to a bariatric surgeon. We offer a summary of recommendations for appropriate follow-up of these pregnancies...

INTRODUCTION: Adjustable gastric banding (AGB) used to be a popular bariatric procedure. However, it fails in more than half of those operated on in the long term, becomes ineffective and must be removed. Therefore, the use of AGB has been in decline globally. Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are the most used bariatric revision surgeries when AGB is removed. CASE REPORT: We present the case of a woman after AGB removal and conversion to SG who developed a stenosis of the sleeve...

To evaluate the efficacy and nutrition of single-anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) in Chinese obese patients in the first postoperative year. Clinical data of 66 obese patients who underwent SADI-S surgery at China-Japan Union Hospital of Jilin University from November 2018 to May 2022 were retrospectively collected. The weight, body mass index (BMI), percentage of excess weight loss (%EWL), and percentage of total weight loss (%TWL) were recorded at 3, 6, and 12 months after surgery...

INTRODUCTION: The ghrelin system, which generates the appetite hormone, is harmed by obesity, a problem of worldwide public health. An efficient way to cure obesity is through bariatric surgery. This randomized controlled study's objective was to assess preoperative diet-related DNA methylation of Ghrelin (GHRL) levels in patients undergoing bariatric surgery. METHODS: The 50 patients who volunteered to participate in the trial were randomly divided into two groups...

BACKGROUND: The link between excess adiposity and carcinogenesis has been well established for multiple malignancies, and cancer is one of the main contributors to obesity-related mortality. The potential role of different weight-loss interventions on cancer risk modification has been assessed, however, its clinical implications remain to be determined. In this clinical review, we present the data assessing the effect of weight loss interventions on cancer risk. METHODS: In this clinical review, we conducted a comprehensive search of relevant literature using MEDLINE, Embase, Web of Science, and Google Scholar databases for relevant studies from inception to January 20, 2024...

BACKGROUND: Gastrocutaneous fistula is a rare complication following Roux-en-Y gastric bypass, a commonly performed bariatric surgery. While most ECFs respond to conservative management, some do not close despite adequate nutritional support, infection source control, and drainage management. As such, the chronicity of these difficult-to-treat wounds can be physically and economically costly to patients. CASE REPORT: A 53-year-old female with a history of Roux-en-Y gastric bypass developed a gastrocutaneous fistula secondary to a perforated gastrojejunal ulcer, requiring immediate surgical intervention...

Nutrition-focused interventions are essential to optimize the bariatric care process and improve health and weight outcomes over time. Clear and detailed reporting of these interventions in research reports is crucial for understanding and applying the findings effectively in clinical practice and research replication. Given the importance of reporting transparency in research, this study aimed to use the Template for Intervention Description and Replication (TIDieR) checklist to evaluate the completeness of intervention reporting in nutritional weight management interventions adjunct to metabolic and bariatric surgery (MBS)...

BACKGROUND: The multicentre randomised trial YOMEGA (NCT02139813) comparing the one anastomosis gastric bypass (OAGB) with the Roux-en-Y gastric bypass (RYGB) confirmed the non-inferiority of OAGB on weight loss outcomes at 24 months. We aimed to report weight loss, metabolic, and safety outcomes at 5 years. METHODS: YOMEGA is a prospective, open-label, non-inferiority, randomised trial conducted at nine centres in France. Inclusion criteria were BMI of 40 kg/m2 or more, or 35 kg/m2 or more with comorbidities...

Bariatric surgery is increasingly recognized as a safe and effective treatment for obesity in patients with chronic kidney disease (CKD), including stages 4, 5, and 5D (on dialysis). Among the available surgical methods, sleeve gastrectomy (SG) is the most commonly performed weight loss procedure and is mainly done to facilitate kidney transplantation (KT). However, many KT candidates treated with SG remain on the transplant waiting list for months to years, with some never receiving a transplant. Therefore, appropriate candidates for SG must be selected, and post-SG management should address the unique needs of this population, with a focus on sustaining the metabolic benefits of surgery while minimizing potential side effects related to rapid weight loss which may inadvertently lead to muscle and bone catabolism...

This study conducted a bibliometric analysis using the Web of Science Core Collection (WOSCC) to explore the relationship between diabetes mellitus and bariatric surgery (BS) from January 1985 to August 2023. No publications were found between 1985 and 1998. However, from 1998 to 2023, a total of 9,496 English articles were identified, accumulating 291,289 citations (241,563 excluding self-citations) and achieving an H-Index of 197. Leading contributors to the field were the United States, China, and Italy...

BACKGROUND: Lifelong follow-up after metabolic/bariatric surgery (MBS) is necessary to monitor for patient outcomes and nutritional status. However, many patients do not routinely follow up with their MBS team. We studied what prompted MBS patients to seek bariatric care after being lost to follow-up and the subsequent treatments they received. STUDY DESIGN: A retrospective cohort study of patients after MBS who had discontinued regular MBS follow-up but represented to the MBS clinic between July 2018 and December 2022 to re-establish care...

Bariatric surgery candidates (BSC) are a highly vulnerable group for mental health impairments. According to the theoretical model of weight stigma, weight-related experienced stigmatization (ES) negatively influences mental health through weight bias internalization (WBI). This study tested this model among BSC and investigated whether this association depends on a negative body image in terms of weight and shape concern as a potential moderator. As part of a German multicenter study, ES, WBI, weight and shape concern, and depressive symptoms were assessed via self-report questionnaires among n = 854 BSC...

Lipid metabolism dysregulation is a critical factor contributing to obesity. To counteract obesity-associated disorders, bariatric surgery is implemented as a very effective method. However, surgery such as Roux-en-Y gastric bypass (RYGB) is irreversible, resulting in life-long changes to the digestive tract. The aim of the present study was to elucidate changes in the fecal microbiota before and after RYGB in relation to blood lipid profiles and proinflammatory IL-6. Here, we studied the long-term effects, up to six years after the RYGB procedure, on 15 patients' gut microbiomes and their post-surgery well-being, emphasizing the biological sex of the patients...

Background: A collaborative prescribing (CP) practice model, established by the endocrinologists, pharmacists, and advanced practice nurses, aims to provide for the postoperative monitoring and medical and nutritional management of stable patients after bariatric surgery. Method: Under the CP agreement, endocrinologists refer patients who have undergone bariatric surgery with stable medical conditions to CP practitioners, comprising senior pharmacists and advanced practice nurses. CP practitioners review the patient's weight loss progress, blood test results and vitals, the sufficiency of micronutrient repletion, adherence to supplements and medications, and chronic disease control...

IMPORTANCE: Among individuals with obesity, 5% or greater weight loss can improve health. Weight management treatments (WMT) include nutrition counseling, very low-calorie meal replacement (MR), antiobesity medications (AOM), and bariatric surgery; however, little is known about how these WMT are associated with weight change among individual patients and populations. OBJECTIVE: To characterize weight status and WMT use among primary care patients and assess associations between WMT and weight trajectories...

Wernicke encephalopathy (WE) is a rare but life-threatening syndrome that is commonly associated with chronic alcoholism. It has also been found to be associated with malnutrition, prolonged parenteral nutrition, hemodialysis, hyperemesis gravidarum, gastroplasty, and AIDS. It usually presents as a clinical triad of confusion, ophthalmoplegia, and gait ataxia. Nystagmus is usually the most common and earliest ophthalmologic sign. We report a case of non-alcoholic WE in a patient who had prior bariatric surgery and was treated for malnutrition and sepsis, with nystagmus being the initial presentation...

BACKGROUND: Childhood obesity is a pressing health crisis of epidemic proportions. Bariatric surgery (BS) is an effective weight loss solution however its role in the paediatric population is contentious owing to the paucity of weight specific and generalised health outcomes. This systematic review and meta-analysis aimed to assess the impact of paediatric BS on bone health. METHODS: This prospectively registered systematic review (PROSPERO ID: CRD42023432035) was performed in accordance with PRISMA guidelines...

Policy Points Health policymakers have insufficiently addressed care for people with obesity (body mass index ≥ 30 kg/m2 ) in the United States. Current federal policies targeting obesity medications reflect this unfortunate reality. We argue for a novel policy framework to increase access to effective obesity therapeutics and care, recognizing that, though prevention is critical, the epidemic proportions of obesity in the United States warrant immediate interventions to augment care. Reducing barriers to and improving the quality of existing anti-obesity medications, intensive behavioral therapy, weight management nutrition and dietary counseling, and bariatric surgery are critical...

OBJECTIVE: This article reviews the clinical presentation, diagnostic evaluation, and treatment of metabolic and toxic myelopathies resulting from nutritional deficiencies, environmental and dietary toxins, drugs of abuse, systemic medical illnesses, and oncologic treatments. LATEST DEVELOPMENTS: Increased use of bariatric surgery for obesity has led to higher incidences of deficiencies in nutrients such as vitamin B12 and copper, which can cause subacute combined degeneration...
