Gastric Sleeve and Bypass in Naples

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.

At the clinic, bariatric operations are carried out by experienced bariatric surgeons:

• Ruslan S. Menzulin — bariatric surgeon and surgical oncologist, 9 years of experience. Trained at Mercy clinic (USA) under Vadim Gushchin, spoke at the World Congress of bariatric surgery in Santiago (2025). Co-author of an international study published in The Lancet.
• Andrey G. Ugay — lead bariatric surgeon, 27 years of experience. Has performed the largest number of SASJ operations in the country. Expert council member of the national Society of Bariatric Surgeons.

Surgery is prescribed only when clear criteria are met

• The patient's body mass index (BMI)
• Overall health and any related chronic conditions
• Failure of previous attempts to lose weight by conventional means

The degree of obesity is mainly assessed with BMI: body weight (kg) divided by height squared (m²). As a rule, surgery is justified when BMI exceeds 40, or exceeds 35 alongside serious related conditions. In some cases lower values may also qualify for surgery if non-surgical approaches have failed.

The two are often mistaken for each other, but their goals are fundamentally different. Bariatric surgery provides medical treatment for obesity and related diseases. Changing how the digestive tract works, it deals with the causes of excess weight and metabolism. Plastic surgery modifies the body's outer contours; it does not treat obesity or affect 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.

Modern laparoscopic technique is what we use. Just 4 small punctures of 5 to 15 mm are needed for the operation. Cosmetic sutures mean the marks are nearly invisible after healing.

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.

Your diet changes in stages: from liquid food to soft, then to solid. The focus is on protein and on limiting high-calorie, fatty food.

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, bariatric surgery makes vitamins a must. Since digestive anatomy is changed, absorption of some nutrients drops, and regular vitamin and mineral supplements become permanent in the patient's 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.
