Surgery is prescribed only when clear criteria are met

• The patient's body mass index (BMI)
• Overall health and any related chronic conditions
• Previous tries at losing weight with ordinary methods have failed

BMI is the principal gauge of how advanced obesity is, found by dividing body weight (kg) by height squared (m²). Typically, a BMI above 40 — or above 35 with serious related conditions — justifies surgery. Some patients with lower values are considered for surgery too, if non-surgical options have failed.

Many mix them up, but they pursue fundamentally different goals. Bariatric surgery medically treats obesity and related diseases by changing how the digestive tract functions, addressing the causes of excess weight and metabolism. Plastic surgery reshapes the external contours of the body; it does not treat obesity or influence metabolism.

Four main types of bariatric surgery are performed at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each is selected individually based on BMI, related conditions and patient goals.

Our approach is modern laparoscopic technique: 4 small punctures of 5 to 15 mm. We use cosmetic sutures, so the marks turn almost invisible after healing.

Recovery is tied to what you do. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: you may swim after 30 days, and other exercise is added bit by bit as weight drops. Travel and holidays: best left until at least a month after surgery.

The diet evolves in steps — from liquids to soft, then solid food — with a focus on protein and limits on high-calorie, fatty food.

Pregnancy after bariatric surgery is possible, though doctors recommend waiting at least 12–18 months. In that time the body stabilizes, weight reaches its target and nutritional status returns to normal.

Yes, vitamins are a must after bariatric surgery. Changes in digestive anatomy mean the body absorbs some nutrients less effectively, so regular vitamin and mineral supplements are part of the patient's life for good.

Although weight regain after bariatric surgery is possible, it is very unlikely if you follow the doctor's advice. Proper eating, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are key.
