Surgery is prescribed only when clear criteria are met

• The patient's body mass index (BMI)
• Overall health and any related chronic conditions
• Weight-loss attempts using conventional methods have not succeeded

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.

These two are frequently confused, although their goals differ at the core. Bariatric surgery is a medical treatment of obesity and related diseases that changes the workings of the digestive tract, targeting the causes of excess weight and metabolism. Plastic surgery corrects outer body contours; it does not treat obesity or change metabolism.

City Medical Centre carries out four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. The choice of method is individual, based on 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.

Eating changes gradually: liquid food first, then soft, then solid. The focus is protein, with high-calorie, fatty food kept to a minimum.

Pregnancy is an option after bariatric surgery, but doctors advise waiting at least 12–18 months. By then the body has stabilized, weight has reached target values and nutritional status has normalized.

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.

After bariatric surgery weight regain can happen, but it is very unlikely if the doctor's advice is followed. What matters is proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists.
