Active clinical trials for "Obesity"

The laparoscopic sleeve-gastrectomy (SG) compared to laparoscopic proximal Roux-Y-gastric bypass (PGB) is as successful in the treatment of morbid obesity in the majority of patients. In case of insufficient weight loss malabsorption can to be added by performing laparoscopic bilious-pancreatic diversion duodenal switch (BPD). The resection of the gastric fundus (LG) leads to changes in gastrointestinal hormones that are possibly different to bypassing the fundus (PGB).

Methods study to characterize early indicators of weight loss in people.

This program aims to help Veterans who take antipsychotic medications lose weight. The investigators use a program based on the American Diabetes Association's "Diabetes Prevention Program," and the investigators have modified it to fit the lifestyles of people with mental illness. All participants are educated about nutrition and cutting down fat intake, how and when to exercise, and the causes of diabetes and how to prevent it. Participants must be Veterans who live within one hour of the West Los Angeles VA hospital.

The purpose of this study is to compare the ability of low calorie high carbohydrate and low calorie high fat/protein diets to decrease abdominal fat in overweight and obese subjects. The investigators will also test the effects of these diets on secondary outcomes including body composition, fluid and electrolyte balance, lipids and lipoproteins, blood pressure, arterial compliance, glucose and insulin metabolism, bone turnover, and measures of satiety.

The purpose of this study is to determine the effect of weight loss and exercise on physical function, body fat and muscle mass, bone strength, and quality of life.

This study aims to investigate the effect of metformin as host-directed therapy in obese/overweight patients with dengue Primary Objective To evaluate the safety and tolerability of metformin in obese/overweight young adults and children with dengue Secondary Objectives To assess the effect of metformin therapy in obese/overweight patients with dengue on physiological, clinical and virological parameters To assess the immunomodulation effects of metformin therapy in obese/overweight patients with dengue To assess difference in gene expression between treatment group compared to non-treatment population

This study will look at the change in participant's body weight from the start to the end of the study. This is to compare the effect on body weight in people taking semaglutide (a new medicine) and people taking "dummy" medicine. Together with the medicine, the participant will also be part of an intensive lifestyle program where the participant will have talks with study staff about healthy food choices, what the participant can do to lose weight and be more physically active. The participant will either get semaglutide or "dummy" medicine - which treatment the participant gets is decided by chance. The participant will need to take 1 injection once a week. The study medicine is injected with a thin needle in a skin fold in the stomach, thigh or upper arm. For the first 2 months the participant will be on a low calorie diet. The diet is made up of bars, shakes and 1 low calorie pre-prepared meal for each day. The study will last for about 1.5 years. The participant will have 32 clinic visits with the study doctor.

In Mexico, 7 out of 10 adults are overweight or obese. The diseases associated with these conditions (diabetes, cardiovascular disease and some cancers) are those that impact the most on the disability-adjusted life years of Mexicans and on their mortality rates. A reduction in body weight of 5-10% can reduce the incidence of obesity related diseases. The gold standard for treating obesity is an intensive lifestyle change program such as the Diabetes Prevention Program (DPP) whose effectiveness has been evaluated in various formats and populations with positive results, including in Mexico. However, the DPP is not accessible to all sectors of the population. To increase its dissemination, the implementation of online interventions based on the DPP (oi-DPP) has been proposed. A systematic review of oi-DPP showed promising results, however, the evidence is limited and the lack of studies of high methodological quality is highlighted. The main objective of this project is to evaluate the efficacy of an oi-DPP for weight loss in Mexican adults with overweight or obesity at 3 months. The study design is a randomized controlled trial with 2 arms: oi-DPP and wait-list control. A 3 months pilot study (n=30) will be conducted prior to the main study to estimate sample size, considering an alpha error of 0.05 and power of 80%. The primary outcome is the mean change in body weight from baseline to 3 months post-baseline between the 2 groups. Secondarily, differences in biochemical parameters (fasting glucose, total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides and gamma glutamyl transferase) from baseline to 3 months will be evaluated, as well as mean changes from baseline to 3 and 6 months in body mass index, waist circumference, systolic and diastolic blood pressure, depression and quality of life scales and the number of participants achieving a weight loss greater than 5% of initial body weight. Body weight will be also evaluated at 6 months post-baseline. The previous measurements will apply both in the pilot study and the study except for the biochemical parameters that will only be included in the main study. The differences between the 2 groups for each variable will be analyzed using a t test for independent samples, in case of having a parametric sample. Otherwise, the Mann-Whitney U test will be used. Analysis will follow the intent-to-treat principle.

The study is investigating new medicines for weight control in people with high body weight. The study looks at how the study medicines work in the body. Participants will get semaglutide and either NNC0165-1562 or "dummy" medicine -which treatment participants get is decided by chance. Participants will get 2 injections per week for 5 months. A study nurse at the clinic will inject the medicine with a thin needle in a skin fold in the stomach. The study will last for about 7 months. Participants will have 27 visits to the clinic.

Obesity or metabolic syndrome is becoming a global epidemic and common health problem, leading to the increase of associated comorbidities such as type 2 diabetes, cardiovascular disease, and certain cancers. This phenomenon is also a serious problem among psychiatric patients due to the increase use of second generation antipsychotics and mood stabilizers such as lithium or valproic acid. These metabolic abnormalities can be regarded as medical comorbidities, and have an impact not only on physical health and increased hospital length of stay, but also on a lower functional outcome, low self-esteem and poorer quality of life and non-compliance to antipsychotics. Green tea is one of the most popular beverages in the world and is believed to have beneficial effects in prevention and treatment of many diseases, such as cancer-prevention, adjunct to chemotherapy for malignancy, to reduce mental and physical stress and improve memory function, to increase bone mineral density, and to decrease body weight. Since weight gain is a common and undesirable side effect with psychiatric medications, the management of it becomes an important issue in clinical practice. In this clinical trial, we will use decaffeinated green tea extract to treat overweight patients with schizophrenia or bipolar disorder in a double-blind, placebo-controlled study design.
