Surgery is prescribed only when clear criteria are met

• The patient's body mass index (BMI)
• Overall health and any related chronic conditions
• Standard approaches to weight loss have not worked before

BMI is the primary tool for judging obesity. The formula: body weight (kg) divided by height squared (m²). Surgery is typically justified at a BMI above 40, or above 35 if there are serious related conditions. At times surgery is also considered with lower figures — provided non-surgical treatment has failed.

Many mix them up, but they pursue fundamentally different goals. Bariatric surgery medically treats obesity and related diseases by changing how the digestive tract functions, addressing the causes of excess weight and metabolism. Plastic surgery reshapes the external contours of the body; it does not treat obesity or influence metabolism.

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

We rely on modern laparoscopic technique. The operation is performed through 4 small punctures of 5 to 15 mm. Cosmetic sutures are used, so after healing the marks are barely visible.

Recovery depends on what you do. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: swimming is allowed after 30 days, other exercise is added gradually as weight drops. Travel and holidays: best planned no earlier than a month 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.

It is possible to get pregnant after bariatric surgery, but doctors recommend a minimum wait of 12–18 months. During it the body stabilizes, weight reaches its target and nutritional status is normalized.

Yes, after bariatric surgery vitamins cannot be skipped. As the digestive anatomy changes, some nutrients are absorbed less well, making regular vitamin and mineral supplements a permanent feature 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.
