Surgery is prescribed only when clear criteria are met
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Past attempts to shed weight in conventional ways were unsuccessful
The main way to assess the degree of obesity is BMI. It is body weight (kg) divided by height squared (m²). Generally, surgery is justified with BMI above 40, or above 35 combined with serious related conditions. Lower values may sometimes be considered for surgery too, when non-surgical measures have failed.
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.
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 work with modern laparoscopic technique. The operation needs only 4 small punctures, 5 to 15 mm each. Cosmetic sutures are applied, so healed marks are almost invisible.
Recovery depends on your activity. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: swimming allowed after 30 days, other exercise added step by step as weight drops. Travel and holidays: plan them no earlier than 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.
Pregnancy is possible after bariatric surgery; doctors advise waiting no less than 12–18 months. This gives the body time to stabilize, for weight to reach target values and nutritional status to normalize.
Yes — vitamins are required after bariatric surgery. With the digestive anatomy changed, some nutrients are absorbed less well, and regular vitamin and mineral supplements become a permanent part of life.
It is possible to regain weight after bariatric surgery, but very unlikely if you follow your doctor's advice. Proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are essential.
