Bariatric Operations in Budapest: Who They Suit

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 bariatric operations at our clinic are done 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
• Past attempts to shed weight in conventional ways were unsuccessful

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.

Though often confused, the two have fundamentally different goals. Bariatric surgery is a medical treatment of obesity and related illnesses; it changes the functioning of the digestive tract to address the causes of excess weight and metabolism. Plastic surgery reshapes the outer contours of the body and neither treats obesity nor affects metabolism.

There are four main types of bariatric surgery at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. BMI, related conditions and the patient's goals guide the individual choice of method.

We apply modern laparoscopic technique, operating through 4 small punctures of 5 to 15 mm. Thanks to cosmetic sutures, the marks are almost invisible once they heal.

Recovery is tied to what you do. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: you may swim after 30 days, and other exercise is added bit by bit as weight drops. Travel and holidays: best left until at least a month after surgery.

You move through diet stages from liquid food to soft and finally solid. Protein comes first, and high-calorie, fatty food is restricted.

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 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 regain is possible after bariatric surgery but very unlikely provided you follow the doctor's advice. Eat properly, avoid high-calorie drinks and keep up regular follow-up with City Medical Centre specialists.
