Active clinical trials for "Obesity, Morbid"

Bariatric surgery has long been recognized as an effective treatment for grade 3 or grade 2 obesity associated with complications. Among the bariatric surgical procedures, roux-en-y gastric bypass (RYGB) was shown to account for 41% of all bariatric operations at least in the United Sates. Sleeve gastrectomy (SG), that was conceived as the first step before performing a RYGB or a biliopancreatic diversion with duodenal switch in patients who were super-obese, has recently emerged as a new restrictive bariatric procedure. Reactive hypoglycemia is a late complication affecting up to 72% of RYGB patients although it seems to occur also after SG, in about 3% of the cases. However, until now no prospective studies have investigated the incidence of hypoglycemia after RYGB nor randomized studies have been undertaken to compare the effect of SG to that of RYGB in terms of incidence of hypoglycemic episodes. The primary aim of the present study is to conduct a 1-year randomized trial to compare the incidence of hypoglycemia after RYGB or SG.

The long term effects of organized lifestyle intervention on weight loss, physical fitness and quality of life in morbidly obese patients have not been extensively studied. The objective of this study is to investigate whether an intensive lifestyle intervention program in a tertiary care clinic (Spesialsykehuset for Rehabilitating) is superior to lifestyle intervention in a primary care setting with respect to long term (4-years) changes in weight loss, physical fitness and quality of life

The purpose of this study is to determine whether the Swedish Adjustable Gastric Band (SAGB) is safe, and effective in achieving weight loss in patients with Morbid Obesity.

The purpose of this study is to test the effect of an implanted device that stimulates the stomach to help obese patients lose weight.

Obesity is a worldwide epidemic with increasing prevalence, specially severe obesity (Body Mass Index (BMI) ≥ 35 kg/m2). It is a multifactorial disease that involves genetic and environmental factors that lead to increased mortality from cardiovascular disease, diabetes, cancer, among others and impairs life quality. Most research on severe obesity focuses on surgical alternatives and their results, thus this clinical trial aims to evaluate the effect of a non-pharmacological approach based on nutritional intervention and supplementation with a functional food, the olive oil. It will analyze the effectiveness of interventions on: weight loss, improvements on body composition and inflammatory profile (TNF-alfa, interleucins 1, 6 and 10, adiponectin), insulin resistance and serum lipids control, changing eating habits and physical activity practice, modification on bone mineral density and sarcopenia, and reduction of cardiovascular risk and other diseases. Also, it will be investigated the influence of polymorphisms (Pro12Ala of PPAR-γ gene, -174G>C of IL6 gene e Trp64Arg of ADRB3 gene) on nutritional intervention effectiveness with and without olive oil. This research looks for improving severely obese patient's care and contributing to effective results by reducing costs and risk treatment. The investigators believe that this informations will contribute significantly to the scientific field, expanding the knowledge about severe obesity.

This study evaluates the omission of incentive spirometry use following bariatric surgery. Half of participants will receive an incentive spirometer while the other half will not. Oxygen saturation and pulmonary complications after surgery will be measured to examine the effectiveness of incentive spirometry.

The purpose of this study is to evaluate the most effective treatment for patients who underwent a Roux-en-Y gastric bypass and developed postoperatively a vitamin B12 deficiency.

The ongoing global rise in the prevalence of overweight and obesity among all ages and among all ethnic groups, figures into a real epidemic phenomenon. This is accompanied by a higher incidence in serious health risks, already present at an early age, "switching-on" the engine towards obesity-related co-morbid diseases and morbid obesity. Weight loss is the only way to avoid systemic and cardiovascular complications of obesity. Weight loss devices have been recently introduced in bariatric surgery, also in children. They mostly require invasive procedures to be applied. Mini-invasive devices would be needed to obtain weight loss in the pediatric population, since the early age of involved patients. Obalon intragastric balloons, are swallowable devices. They are filled with liquid or air, and have been used to induce weight loss in obese adults. The investigators aimed to perform a pilot study in pediatrics, and monitor weight loss, metabolic and cardiovascular parameters modifications, after up-to-3 Obalon® Gastric Balloons placement.

Objective: to assess the effect of gastric bypass on HDL-cholesterol concentration and its Apolipoprotein A4 content at 1 year following bariatric surgery in comparison with a hypocaloric diet. Secondary aim was to measure total cholesterol and triglycerides levels as well as insulin sensitivity after interventions. Summary Background Data: Very few prospective uncontrolled studies have investigated the effects of Roux-en-Y gastric bypass (RYGB) on cardiovascular risk factors. No controlled studies had as primary goal the changes in HDL-cholesterol after gastric bypass. Methods: Forty subjects with a BMI>40 or ≥35 kg/m2 in the presence of diabetes were enrolled. Twenty of them were operated of RYGB while 20 received lifestyle modification suggestions and medical therapy for obesity complications (diabetes, hypertension and hyperlipidemia).

The prevalence of severe pediatric obesity is on the rise and youth with this condition are at elevated risk for developing chronic diseases such as cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM). Topiramate, a medication approved by the Food and Drug Administration (FDA) for the treatment of seizures in adults and children, is associated with weight loss. Although not FDA approved for the treatment of obesity, studies in obese adults have demonstrated weight reduction of approximately 5% with 6-12 months of therapy. However, the weight loss effect of topiramate has never been evaluated among children and adolescents. Therefore, the goal of this pilot study is to evaluate the safety and efficacy of 24 weeks of topiramate therapy with a 4-week run-in of meal replacement therapy in adolescents with severe obesity. The primary hypothesis is that 4 weeks of meal replacement therapy followed by 24 weeks of topiramate will have a larger average percent decline in BMI between baseline and 28 weeks compared to meal replacement therapy followed by placebo.
