Bariatric Surgery

What problems can be caused by morbid obesity? Obesity causes a variety of metabolic diseases, such as diabetes mellitus, cardiovascular disease, and skeletal system disorders.

When must morbid obesity be operated on? From a BMI of 40kg/m2 or 35kg/m2 with associated comorbidities.

Which examinations are necessary before the operation or for health insurance approval? An internal-endocrinological examination, a clinical psychological assessment, a professional diet consultation, as well as an upper abdominal sonography (gallstones?) and a gastroscopy (hiatal hernia? biopsies).

How is a gastric bypass surgery performed? A gastric bypass is operated laparoscopically or minimally invasively via 4-5 small skin incisions. The stomach is made smaller and part of the small intestine is bypassed to reduce the absorption area for food.

What should be considered after the surgery? Lifelong internistic care is needed after the operation.
