Surgery is prescribed only when clear criteria are met

• The patient's body mass index (BMI)
• Overall health and any related chronic conditions
• Conventional weight-loss methods have failed in past attempts

The degree of obesity is mainly assessed with BMI: body weight (kg) divided by height squared (m²). As a rule, surgery is justified when BMI exceeds 40, or exceeds 35 alongside serious related conditions. In some cases lower values may also qualify for surgery if non-surgical approaches have failed.

Many people confuse the two, but their goals are fundamentally different. Bariatric surgery is a medical treatment for obesity and related diseases. It changes how the digestive tract works, addressing the causes of excess weight and metabolism. Plastic surgery reshapes the body's outer contours; it does not treat obesity or affect metabolism.

Four main bariatric surgery types are available at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. The method is picked individually, considering BMI, related conditions and the patient's goals.

Modern laparoscopic technique allows the operation through 4 small punctures of 5 to 15 mm. Cosmetic sutures make the marks almost invisible when fully healed.

Recovery time depends on the activity. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: swimming allowed after 30 days, other exercise gradually added as weight goes down. Travel and holidays: plan no sooner than one 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.

Bariatric surgery does not rule out pregnancy, but doctors suggest waiting 12–18 months or more. During that time the body settles, weight reaches target values and nutrition status normalizes.

Yes, taking vitamins after bariatric surgery is mandatory. Because digestion is anatomically altered, the body absorbs some nutrients poorly, so regular vitamin and mineral supplements stay in the patient's life permanently.

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.
