Weight Loss Surgery in Alicante

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.

Bariatric operations at the clinic are performed 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
• 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.

Many mix them up, but they pursue fundamentally different goals. Bariatric surgery medically treats obesity and related diseases by changing how the digestive tract functions, addressing the causes of excess weight and metabolism. Plastic surgery reshapes the external contours of the body; it does not treat obesity or influence 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.

Our approach is modern laparoscopic technique: 4 small punctures of 5 to 15 mm. We use cosmetic sutures, so the marks turn almost invisible after healing.

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.

Your diet changes step by step: from liquid food to soft and then to solid. The emphasis is on protein and on cutting high-calorie, fatty food.

Pregnancy after bariatric surgery can happen, though doctors advise holding off at least 12–18 months. In this period the body becomes stable, weight reaches target values and nutritional status normalizes.

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.

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.
