Gastric Sleeve and Bypass in Stuttgart

Yes, bariatric surgery is the medical term for it. At City Medical Centre the main methods are sleeve gastrectomy (gastric sleeve) and gastric bypass; the surgeon chooses the method by your BMI and health.

Usually a BMI over 40, or over 35 with related health conditions. The surgeon confirms whether surgery suits you at the consultation.

Surgery is prescribed only when clear criteria are met

• The patient's body mass index (BMI)
• Overall health and any related chronic conditions
• Weight-loss attempts using conventional methods have not succeeded

BMI is the primary tool for judging obesity. The formula: body weight (kg) divided by height squared (m²). Surgery is typically justified at a BMI above 40, or above 35 if there are serious related conditions. At times surgery is also considered with lower figures — provided non-surgical treatment has failed.

Many mix them up, but they pursue fundamentally different goals. Bariatric surgery medically treats obesity and related diseases by changing how the digestive tract functions, addressing the causes of excess weight and metabolism. Plastic surgery reshapes the external contours of the body; it does not treat obesity or influence metabolism.

Four main types of bariatric surgery are performed at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each is selected individually based on BMI, related conditions and patient goals.

We use modern laparoscopic technique. The operation is done through 4 small punctures of 5 to 15 mm. Cosmetic sutures are placed, so once healed the marks become almost invisible.

Recovery varies with your activities. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: swimming is permitted after 30 days; other exercise is added gradually as weight decreases. Travel and holidays: best scheduled at least a month after surgery.

In stages, your diet goes from liquid to soft to solid food. The main focus is protein and restricting high-calorie, fatty food.

After bariatric surgery pregnancy is possible, yet doctors recommend at least 12–18 months of waiting. Meanwhile the body stabilizes, weight arrives at target values and nutritional status normalizes.

Yes, after bariatric surgery vitamins are a must. The altered digestive anatomy reduces absorption of some nutrients, which makes regular vitamin and mineral supplements a permanent part of the patient's life.

Weight can be regained after bariatric surgery, but this is very unlikely with the doctor's advice followed. Proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are crucial.
