About the department

The department of obesity and metabolic surgery (bariatric surgery) at Helios Hospital Berlin-Buch supports severely overweight people individually in losing weight and helping to maintain the reduced weight. It is the largest obesity centre in Germany, and one of the largest globally, around 800 surgeries performed yearly. Experienced surgeons have already served over 7,500 procedures. The treatment approach is based on expertise and trust. In addition, patients can take local nutrition and therapy courses online, not only as part of the six-month surgical preparation, to prepare continuously and flexibly for the operation and maintain their weight after the procedure.

In the run-up to a surgical procedure, the patients complete an outpatient, guideline-based preparation that usually lasts six months, including a change in diet and support from nutritionists and psychologists. Several types of surgery for obesity are available. The team accompanies patients holistically and supports them both in the run-up to their surgical intervention and aftercare because obesity is a chronic disease and requires lifelong medical support.

Treatment and diagnostic focus of the department

Surgery for obesity:

  • Gastric banding (The stomach is divided into a small forestomach and a residual stomach with a silicone band. The passage between the two is narrowed so that the food initially remains in the forestomach and triggers a faster feeling of satiety.)
  • Sleeve resection (In this procedure, much of the stomach is removed. It can be assumed that 75-80% of excess weight can be reduced.)
  • Gastric bypass (The stomach reduction is combined with a partial bypass of the small intestine. It is assumed that 80-85% of excess weight can be reduced.)
  • Mini bypass (omega loop bypass) (The mini bypass or "omega loop bypass" is a relatively new procedure. The stomach is reduced and connected with a loop of the small intestine.)

Sequelae of obesity:

  • Type II diabetes mellitus
  • Arteriosclerosis
  • Stroke
  • Coronary heart disease
  • Hypertension
  • Dyslipidemia
  • Gallstone disease
  • Cancer development
  • Sleep apnea syndrome
  • Joint disease
  • Skin disease
  • Psychosocial consequences
