Weight Loss Surgery in Bari: Sleeve, Bypass, SADI-S

Yes, bariatric surgery is the medical term for it. At City Medical Centre the main methods are sleeve gastrectomy (gastric sleeve) and gastric bypass; the surgeon chooses the method by your BMI and health.

Usually a BMI over 40, or over 35 with related health conditions. The surgeon confirms whether surgery suits you at the consultation.

Surgery is prescribed only when clear criteria are met

• The patient's body mass index (BMI)
• Overall health and any related chronic conditions
• Conventional weight-loss methods have failed in past attempts

To gauge obesity, doctors rely primarily on BMI, which equals body weight (kg) divided by the square of height (m²). An operation is usually warranted with a BMI over 40, or over 35 with serious associated conditions. Occasionally surgery is weighed at lower values as well, once non-surgical options have failed.

Though often confused, the two have fundamentally different goals. Bariatric surgery is a medical treatment of obesity and related illnesses; it changes the functioning of the digestive tract to address the causes of excess weight and metabolism. Plastic surgery reshapes the outer contours of the body and neither treats obesity nor affects metabolism.

The four main types of bariatric surgery at City Medical Centre are sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each method is matched individually to BMI, related conditions and the patient's goals.

The operation uses modern laparoscopic technique, through 4 small punctures of 5 to 15 mm. We place cosmetic sutures, and after healing the marks become almost invisible.

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.

Diet changes happen in stages, from liquids to soft food and then solids. It centers on protein and limits high-calorie, fatty food.

Bariatric surgery does not rule out pregnancy, but doctors suggest waiting 12–18 months or more. During that time the body settles, weight reaches target values and nutrition status normalizes.

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.

Regain after bariatric surgery is possible, but very unlikely if you follow the doctor's advice. Proper nutrition, no high-calorie drinks and regular follow-up visits with City Medical Centre specialists make the difference.
