Surgical Treatment of Obesity in Prague

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.

Bariatric surgery at the clinic is performed 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
• Previous efforts at weight loss through standard methods did not work

BMI is the key measure used to assess how severe obesity is. You get it by dividing body weight (kg) by height squared (m²). Surgery is generally justified at a BMI above 40, or above 35 when serious related conditions are present. Sometimes it is also considered at lower values — when non-surgical methods have not worked.

It is common to confuse them, but their goals are fundamentally different. Bariatric surgery treats obesity and related diseases medically. By changing how the digestive tract works, it addresses the causes of excess weight and metabolism. Plastic surgery shapes the body's outer contours; it does not treat obesity and has no effect on metabolism.

City Medical Centre performs four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each method is chosen individually based on BMI, related conditions and the patient's goals.

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.

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.

The diet evolves in steps — from liquids to soft, then solid food — with a focus on protein and limits on high-calorie, fatty food.

You can become pregnant after bariatric surgery, but doctors advise a wait of at least 12–18 months. Over this period the body stabilizes, weight hits target values and nutritional status normalizes.

Yes, vitamins are essential after bariatric surgery. As digestive anatomy changes, the body absorbs certain nutrients less well, so regular vitamin and mineral supplements become a lasting part of the patient's 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.
