Severe Obesity: Bariatric Surgery vs. Life-Style-Intervention (WAS)
The purpose of this study is to investigate the effects of gastric bypass in comparison to a intensive life style intervention on cardiac function and quality of life in patients with morbid obesity.

intensive life style intrvention
intensive life style intervention over 18 months including movement, psychological meetings and change in food intake
|Behavioral: intensive life style intervention|
|gastric bypass||Procedure: gastric bypass|
Obesity ia associated with an elevated risk for cardiovascular diseases especially heart failure, atrial fibrillation and death from cardiovascular causes. Obese patients commonly have left ventricular hypertrophy and left atrial enlargement.
Conservative weight loss therapy is not effective in most patients with morbid obesity.Bariatric surgery is the only way to decrease weight effectively and permanently. Only few data are published concerning cardiac effects of bariatric surgery.
We randomize patients with morbid obesity for either gastric bypass or intensive life style intervention over 18 months and investigate the effects on cardiac function, weight and quality of life.
