Bariatric Surgery in Athens with a Contract Guarantee

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

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.

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.

Four main bariatric surgery types are available at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. The method is picked individually, considering BMI, related conditions and the patient's goals.

Modern laparoscopic technique is what we use. Just 4 small punctures of 5 to 15 mm are needed for the operation. Cosmetic sutures mean the marks are nearly 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.

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

Pregnancy is possible after bariatric surgery; doctors advise waiting no less than 12–18 months. This gives the body time to stabilize, for weight to reach target values and nutritional status to normalize.

Yes, vitamins become essential after bariatric surgery. The changed digestive anatomy lowers absorption of some nutrients, so regular vitamin and mineral supplements turn into a permanent part of the patient's 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.
