Bariatric Surgery for Patients from Hanover

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, bariatric operations are carried out by experienced bariatric surgeons:

• 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
• Weight-loss attempts using conventional methods have not succeeded

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.

The two are often confused, yet their goals differ fundamentally. Bariatric surgery is a medical treatment for obesity and its related diseases. It alters how the digestive tract works, tackling the causes of excess weight and metabolism. Plastic surgery changes the body's outer contours; it neither treats obesity nor affects 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.

Our approach is modern laparoscopic technique: 4 small punctures of 5 to 15 mm. We use cosmetic sutures, so the marks turn almost invisible after healing.

Your recovery depends on your activities. Office work: in 2–4 weeks. Physical work: in 1.5 months. Sport and activity: swimming after 30 days, with other exercise introduced gradually as weight drops. Travel and holidays: plan them a month or more after surgery.

Your meals progress in stages: liquid food, soft food, then solid. The stress is on protein and on reducing 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, taking vitamins after bariatric surgery is mandatory. Because digestion is anatomically altered, the body absorbs some nutrients poorly, so regular vitamin and mineral supplements stay in the patient's life permanently.

After bariatric surgery weight regain can happen, but it is very unlikely if the doctor's advice is followed. What matters is proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists.
