Surgery is prescribed only when clear criteria are met

• The patient's body mass index (BMI)
• Overall health and any related chronic conditions
• Past attempts to shed weight in conventional ways were unsuccessful

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 performs four core types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Selection is individual and takes into account BMI, related conditions and the patient's goals.

Using modern laparoscopic technique, we perform the operation via 4 small punctures of 5 to 15 mm. Cosmetic sutures are placed, leaving marks that are nearly invisible after healing.

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.

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

After bariatric surgery pregnancy is possible, yet doctors recommend at least 12–18 months of waiting. Meanwhile the body stabilizes, weight arrives at 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 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.
