Surgery is prescribed only when clear criteria are met

• The patient's body mass index (BMI)
• Overall health and any related chronic conditions
• Failure of previous attempts to lose weight by conventional means

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.

City Medical Centre provides four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. We choose each method individually by BMI, related conditions and the patient's goals.

The operation uses modern laparoscopic technique, through 4 small punctures of 5 to 15 mm. We place cosmetic sutures, and after healing the marks become almost invisible.

Recovery depends on what you plan to do. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: swimming after 30 days, other exercise phased in as weight drops. Travel and holidays: preferably not earlier than one month after surgery.

Your diet changes step by step: from liquid food to soft and then to solid. The emphasis is on protein and on cutting high-calorie, fatty food.

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, vitamins after bariatric surgery are necessary. The body absorbs certain nutrients less well due to the changed digestive anatomy, so regular vitamin and mineral supplements become 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.
