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

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 confused, yet their goals differ fundamentally. Bariatric surgery is a medical treatment for obesity and its related diseases. It alters how the digestive tract works, tackling the causes of excess weight and metabolism. Plastic surgery changes the body's outer contours; it neither treats obesity nor affects metabolism.

At City Medical Centre there are four main types of bariatric surgery — sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Every method is chosen individually from BMI, related conditions and the patient's goals.

Our surgeons use modern laparoscopic technique: the operation goes through 4 small 5 to 15 mm punctures. With cosmetic sutures, the marks become almost invisible once healed.

Recovery depends on what you plan to do. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: swimming after 30 days, other exercise phased in as weight drops. Travel and holidays: preferably not earlier than one month after surgery.

In stages, your diet goes from liquid to soft to solid food. The main focus is protein and restricting high-calorie, fatty food.

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, vitamins after bariatric surgery are necessary. The body absorbs certain nutrients less well due to the changed digestive anatomy, so regular vitamin and mineral supplements become a permanent part of the patient's life.

Weight can be regained after bariatric surgery, but this is very unlikely with the doctor's advice followed. Proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are crucial.
