Background & aims Bariatric surgery is increasingly common in the fight against morbid obesity. However, after this intervention, it is not fully understood the evolution of weight loss and how body composition changes. The objective of this work is to study the evolution after surgery of weight and body composition of obese patients that underwent bariatric surgery. Methods In this retrospective and prospective study, we studied initially BMI and body composition of obese patients who attended nutritional appointments at Centro Hospitalar …

Abstract Purpose Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are the most popular procedures to treat morbid obesity among bariatric surgeries. However, only few studies have compared the changes in body composition, dietary intake, and substrate oxidation after LRYGB and LSG. Therefore, the present study was conducted to compare the changes in body composition, dietary intake, and substrate oxidation 6 months postoperatively in obese patients who underwent LRYGB …

Aims: To investigate the relationship between extracellular water to total body water ratio (ECW/TBW) in bioimpedance analysis (BIA) and clinical parameters in hepatitis viruses related to liver diseases. Methods: ECW/TBW was compared in patients with hepatitis B virus (HBV, n= 85) and hepatitis C virus (HCV, n= 440) related liver diseases. We also examined factors linked to mild to severe overhydrated state (ECW/TBW≥ 0.4). Results: The median ECW/TBW in the HCV group was 0.388 (range, 0.365–0.433), while that in the HBV …

Obesity represents a major public health problem and is the fifth leading risk factor for mortality. Morbid obesity is associated with chronic systemic inflammation which increases the risk of comorbidities. Bariatric surgery (BS) is considered an effective intervention for obese patients. However, BS is associated with dietary restriction, potentially limiting physical activity. Whole-body neuromuscular electrical stimulation (WBS) could represent an innovative option for the rehabilitation of BS patients, especially during the early …

Background There is an increased interest in understanding how variation in body composition (BC) and energy expenditure is related to successful weight loss after surgery. It has been suggested that low resting metabolic rate (RMR) could be associated with poor weight loss. Objectives To determine the relation among changes in BC, RMR, and weight loss after bariatric surgery. Setting University tertiary care hospital, Brazil. Methods A cohort of 45 patients submitted to bariatric surgery was prospectively studied. BC was evaluated by …

Background Patients with morbid obesity are complicated with metabolic diseases and have a high incidence of non-alcoholic fatty liver disease (NAFLD), including non-alcoholic steatohepatitis (NASH). Methods We report on a follow-up study of a cohort included 102 obese patients (55 males and 47 females, mean age 42.9±10.6 years) undergoing bariatric surgery for the management of morbid obesity. Abdominal computed tomography was performed before and 1 year after surgery. Anthropometric and biochemical measurements …

Introduction The increased visceral fat in patients with obesity can increase the technical difficulty of surgery. This study was performed to evaluate a preoperative 20‐day very low‐calorie diet for obesity before laparoscopic gastrectomy for gastric cancer. Methods This prospective single‐center study involved patients with obesity who were planning to undergo laparoscopic gastrectomy for gastric cancer. Obesity was defined according to the Japanese criteria: BMI≥ 25 kg/m2 or waist circumference≥ 85 cm in men and≥ 90 cm in …

Background The aim is to evaluate the effects of IGB in overweight or class I obese patients, by analyzing body composition and quality of life (QOL). Methods Prospective study including patients with BMI 27–34.9 kg/m 2. body composition analysis (BCA) was performed before IGB implantation and its removal, after 6 months of treatment. QOL was assessed by the Short Form 36 (SF-36) Health Survey at baseline and after treatment. Results Forty patients were included in this study, but four were excluded. The total weight …

Purpose Given the importance of physical activities for health outcomes, it is still unclear whether bariatric surgery per se and the standard care after surgery would result in an increase of physical activity level. This study aimed to determine physical activities …
