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

Obesity is graded mainly by BMI, calculated as body weight (kg) over height squared (m²). A BMI above 40 usually justifies surgery, as does a BMI above 35 with serious related conditions. In certain cases surgery is considered at lower values too, if approaches without surgery have not succeeded.

The two are often mistaken for each other, but their goals are fundamentally different. Bariatric surgery provides medical treatment for obesity and related diseases. Changing how the digestive tract works, it deals with the causes of excess weight and metabolism. Plastic surgery modifies 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.

Our surgeons use modern laparoscopic technique: the operation goes through 4 small 5 to 15 mm punctures. With cosmetic sutures, the marks become almost invisible once healed.

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.

Stage by stage, you move from liquid food to soft and then solid. Priority goes to protein, and high-calorie, fatty food is limited.

Pregnancy after bariatric surgery can happen, though doctors advise holding off at least 12–18 months. In this period the body becomes stable, weight reaches target values and nutritional status normalizes.

Yes, bariatric surgery makes vitamins a must. Since digestive anatomy is changed, absorption of some nutrients drops, and regular vitamin and mineral supplements become permanent in the patient's life.

Weight can come back after bariatric surgery, but this is very unlikely if you follow your doctor's advice. Proper nutrition, skipping high-calorie drinks and regular follow-up with City Medical Centre specialists are key.
