Study Evaluating Metabolic Syndrome in Subjects Undergoing Gastric Bypass Bariatric Syndrome
An observational study of Morbid Obesity and Metabolic Disease, run by Wyeth is now a wholly owned subsidiary of Pfizer at 17 sites in 3 countries.
Trial summary
Metabolic syndrome is rapidly emerging as an epidemic of global proportions and its definition is still evolving. Patients with this syndrome are at increased risk for cardiovascular disease, and at increased risk of mortality from cardiovascular disease. Read more about this study

About this study
Official title: A Prospective, Longitudinal Multicenter, Nontreatment, Exploratory Biomarker Study of Metabolic Syndrome in Subjects Undergoing Laparoscopic Roux-En-Y Gastric Bypass Bariatric Syndrome
Metabolic syndrome is rapidly emerging as an epidemic of global proportions and its definition is still evolving. Patients with this syndrome are at increased risk for cardiovascular disease, and at increased risk of mortality from cardiovascular disease.
Metabolic syndrome is strongly associated with obesity, and more specifically with abdominal obesity. Abdominal obesity, comprises two main components: visceral (VAT) and subcutaneous (SAT) adipose tissue depots, with VAT reported as more metabolically active than SAT, and thought to play a major role in the metabolic disturbances associated with obesity and metabolic syndrome.

Non-alcoholic fatty liver disease (NAFLD) is fast becoming the most common liver disease and is associated with obesity, insulin resistance and metabolic syndrome.
Bariatric surgery has yielded dramatic results including longitudinal loss of excess body weight and either complete reversal or significant improvement of several features of metabolic syndrome, NAFLD, and nonalcoholic steatohepatitis (NASH) in obese patients.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Metabolic syndrome is rapidly emerging as an epidemic of global proportions and its definition is still evolving. Patients with this syndrome are at increased risk for cardiovascular disease, and at increased risk of mortality from cardiovascular disease.
Metabolic syndrome is strongly associated with obesity, and more specifically with abdominal obesity.
