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

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.

It is common to confuse them, but their goals are fundamentally different. Bariatric surgery treats obesity and related diseases medically. By changing how the digestive tract works, it addresses the causes of excess weight and metabolism. Plastic surgery shapes the body's outer contours; it does not treat obesity and has no effect on 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.

We use modern laparoscopic technique. The operation is done through 4 small punctures of 5 to 15 mm. Cosmetic sutures are placed, so once healed the marks become almost invisible.

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.

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

You can become pregnant after bariatric surgery, but doctors advise a wait of at least 12–18 months. Over this period the body stabilizes, weight hits target values and nutritional status normalizes.

Yes, after bariatric surgery vitamins cannot be skipped. As the digestive anatomy changes, some nutrients are absorbed less well, making regular vitamin and mineral supplements a permanent feature 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.
