Bariatric Surgery for Patients from Wuppertal

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.

At the clinic, experienced bariatric surgeons perform the bariatric operations:

• Ruslan S. Menzulin — bariatric surgeon and surgical oncologist, 9 years of experience. Trained at Mercy clinic (USA) under Vadim Gushchin, spoke at the World Congress of bariatric surgery in Santiago (2025). Co-author of an international study published in The Lancet.
• Andrey G. Ugay — lead bariatric surgeon, 27 years of experience. Has performed the largest number of SASJ operations in the country. Expert council member of the national Society of 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
• Past attempts to shed weight in conventional ways were unsuccessful

Obesity is graded mainly by BMI, calculated as body weight (kg) over height squared (m²). A BMI above 40 usually justifies surgery, as does a BMI above 35 with serious related conditions. In certain cases surgery is considered at lower values too, if approaches without surgery have not succeeded.

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

City Medical Centre performs four core types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Selection is individual and takes into account BMI, related conditions and the patient's goals.

The operation uses modern laparoscopic technique, through 4 small punctures of 5 to 15 mm. We place cosmetic sutures, and after healing the marks become almost invisible.

The recovery timeline depends on your activity. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: swimming allowed from 30 days, other exercise added gradually as weight comes down. Travel and holidays: best planned at least a month after surgery.

Your diet changes step by step: from liquid food to soft and then to solid. The emphasis is on protein and on cutting high-calorie, fatty food.

Pregnancy after bariatric surgery can happen, though doctors advise holding off at least 12–18 months. In this period the body becomes stable, weight reaches 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.

Regain after bariatric surgery is possible, but very unlikely if you follow the doctor's advice. Proper nutrition, no high-calorie drinks and regular follow-up visits with City Medical Centre specialists make the difference.
