Active clinical trials for "Obesity"

We will give intravenous fat molecules to help us understand how the fat that is released from peoples fat cells is used. This will be done when people are eating, not eating and walking.

This is a prospective chart review/data collection study of natural orifice translumenal endoscopic surgery (NOTES) for sleeve gastrectomy, that will include questionnaires administered throughout the study. Subjects enrolled will be those intending to have a transvaginal NOTES sleeve gastrectomy. Data will be collected and reviewed through 12 months post-op.

The purpose of this study is to determine abnormal neuro-hormonal mechanisms that may impair the ability to feel full and which therefore, may lead to obesity.

In this study the investigators hypothesize that pathological alterations in adipose tissue biology already occur during the development and progression of obesity in children and adolescents. The investigators aim to identify and characterize mechanisms and molecular targets that affect the development of adipose tissue and ensuing obesity in childhood and adolescence.

The purpose of the study is to determined the prevalence of obesity-hypoventilation syndrome in patients with metabolic syndrom.

Bariatric surgery is generally recommended for obese people with a body mass index (BMI) of at least 40kg/m2, and for people with BMI 35 kg/m2 and serious coexisting medical conditions such as diabetes. A variety of studies showed that it cause significant weight loss, recovery from diabetes and improvement in cardiovascular risk factors, such as blood pressure. The recent guidelines suggest that patients with a BMI of more than 30 kg/m2 with co morbidities is a candidate for bariatric surgery. However, the patients with diabetes in Chinese has lower BMI than that in west country. Therefore, this research is designed to observe whether bariatric surgery reduce blood pressure in patients with diabetes and relatively lower BMI.

Obesity is a serious medical problem because it increases the risk of cardiovascular disease (CVD), type 2 diabetes mellitus, and certain forms of cancer. The definition of obesity is based on an excess of body fat, not of BMI. However, BMI is the reference used to establish a graded classification of weight relative to height. Although BMI is widely used as a simple surrogate measure of body fat and has been shown to correlate closely with adiposity, it would be more appropriate to determine body fat percentage and to use this value for classification purposes. The present study contemplates the determination of the per cent body fat with the aim of establishing new diagnostic and therapeutic criteria according to the associated comorbidities.

The study in aimed to investigate epidemiology of risk factors in Russian Federation its prognostic value aimed on acceptance of national specific definition of metabolic syndrome and guidelines for its management.

Cardiovascular risk factors and psycho-social characteristics will be determined in obese and non-obese patients in the setting of primary medical care.

The study aims to investigate the characteristics of subjects with hypertension at onset among a cohort of apparently healthy subjects, with overweight or obesity (BMI ≥ 25 Kg / m2), and free of any drug treatment at the baseline. The evaluation includes anthropometric (weight, height, BMI, waist circumference), haematochemical (hormones, metabolic and routine) parameters and the screening for hypertension with ABPM. The diagnosis of hypertension is made in accordance with the 2017 guidelines of the American College of Cardiology / American Heart Association ACC / AHA.
