Gastric Sleeve and Bypass in Frankfurt am Main

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
• Standard approaches to weight loss have not worked before

BMI is the principal gauge of how advanced obesity is, found by dividing body weight (kg) by height squared (m²). Typically, a BMI above 40 — or above 35 with serious related conditions — justifies surgery. Some patients with lower values are considered for surgery too, if non-surgical options have failed.

These two are frequently confused, although their goals differ at the core. Bariatric surgery is a medical treatment of obesity and related diseases that changes the workings of the digestive tract, targeting the causes of excess weight and metabolism. Plastic surgery corrects outer body contours; it does not treat obesity or change 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.

Modern laparoscopic technique allows the operation through 4 small punctures of 5 to 15 mm. Cosmetic sutures make the marks almost invisible when fully healed.

Recovery depends on what you do. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: swimming is allowed after 30 days, other exercise is added gradually as weight drops. Travel and holidays: best planned no earlier than a month after surgery.

Your diet changes in stages: from liquid food to soft, then to solid. The focus is on protein and on limiting high-calorie, fatty food.

Pregnancy after bariatric surgery is possible, but doctors advise waiting at least 12–18 months. During this time the body stabilizes, weight reaches target values and nutritional status normalizes.

Yes — vitamins are required after bariatric surgery. With the digestive anatomy changed, some nutrients are absorbed less well, and regular vitamin and mineral supplements become a permanent part of 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.
