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 main tool for assessing the degree of obesity. It is calculated by dividing body weight (kg) by height squared (m²). Surgery is usually justified with a BMI above 40, or above 35 with serious related conditions. In some cases surgery is considered at lower values too — if non-surgical approaches have failed.

Many confuse the two, yet their purposes are fundamentally different. Bariatric surgery is medicine's treatment for obesity and related diseases: it changes how the digestive tract operates and addresses the causes of excess weight and metabolism. Plastic surgery reshapes outer contours of the body without treating obesity or affecting 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.

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 varies with your activities. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: swimming is permitted after 30 days; other exercise is added gradually as weight decreases. Travel and holidays: best scheduled at least a month after surgery.

You move through diet stages from liquid food to soft and finally solid. Protein comes first, and high-calorie, fatty food is restricted.

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, vitamins after bariatric surgery are a must. Because the digestive anatomy changes, the body absorbs some nutrients less well, 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.
