Weight Loss Surgery in Bochum: Sleeve, Bypass, SADI-S

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.

The clinic's bariatric procedures are performed by experienced bariatric surgeons:

Surgery is prescribed only when clear criteria are met

• The patient's body mass index (BMI)
• Overall health and any related chronic conditions
• Previous tries at losing weight with ordinary methods have failed

BMI is the key measure used to assess how severe obesity is. You get it by dividing body weight (kg) by height squared (m²). Surgery is generally justified at a BMI above 40, or above 35 when serious related conditions are present. Sometimes it is also considered at lower values — when non-surgical methods have not worked.

Many people confuse the two, but their goals are fundamentally different. Bariatric surgery is a medical treatment for obesity and related diseases. It changes how the digestive tract works, addressing the causes of excess weight and metabolism. Plastic surgery reshapes the body's outer contours; it does not treat obesity or affect metabolism.

City Medical Centre offers four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. The method is chosen individually according to BMI, related conditions and the patient's goals.

We work with modern laparoscopic technique. The operation needs only 4 small punctures, 5 to 15 mm each. Cosmetic sutures are applied, so healed marks are almost invisible.

When you recover depends on your activity. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: swimming is fine after 30 days; other exercise gets added gradually as weight drops. Travel and holidays: best planned from a month after surgery.

Eating changes gradually: liquid food first, then soft, then solid. The focus is protein, with high-calorie, fatty food kept to a minimum.

Getting pregnant after bariatric surgery is possible, but doctors advise waiting at least 12–18 months, so the body can stabilize, weight can reach target values and nutritional status can normalize.

Yes, vitamins after bariatric surgery are necessary. The body absorbs certain nutrients less well due to the changed digestive anatomy, so regular vitamin and mineral supplements become a permanent part of the patient's life.

Although weight regain after bariatric surgery is possible, it is very unlikely if you follow the doctor's advice. Proper eating, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are key.
