Center for Obesity and Metabolic Surgery

As the University Center for Obesity and Metabolic Surgery, we offer comprehensive and holistic care to patients suffering from severe overweight/obesity and related metabolic diseases.

Obesity has been recognized as a chronic nutritional and metabolic disease since 1997. The number of people affected has risen dramatically in recent decades, so much so that doctors are already talking about an epidemic. However, those affected still often feel that they are on their own with their illness. In order to better address the needs of patients with obesity and to give the issue the appropriate weight, the University Hospital Zurich has established the Zurich Obesity Center. This helps those affected to find out more about the topic and to find an individual treatment that promises lasting success. Here we have compiled everything you need to know about obesity and its treatment.

We accompany you personally and supportive

The abbreviation BMI stands for Body Mass Index. This index is calculated as the ratio of weight divided by height squared. This puts body weight in relation to body height. The result shows whether a person is of normal weight (BMI between 18 and 24.9 kg/m2), overweight (25-29.9 kg/m2) or obese (30 kg/m2 or more).
