Gastric Sleeve and Bypass in Copenhagen

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.

Experienced bariatric surgeons perform the bariatric operations at the clinic:

• 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.

Surgery is prescribed only when clear criteria are met

• The patient's body mass index (BMI)
• Overall health and any related chronic conditions
• Previous efforts at weight loss through standard methods did not work

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.

People often confuse these two, though their aims are fundamentally different. Bariatric surgery is medical treatment of obesity and associated diseases. It changes the way the digestive tract works, acting on the causes of excess weight and on metabolism. Plastic surgery alters outer body contours and does not treat obesity or affect metabolism.

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

We use modern laparoscopic technique. The operation is done through 4 small punctures of 5 to 15 mm. Cosmetic sutures are placed, so once healed the marks become almost invisible.

Your recovery depends on your activities. Office work: in 2–4 weeks. Physical work: in 1.5 months. Sport and activity: swimming after 30 days, with other exercise introduced gradually as weight drops. Travel and holidays: plan them a month or more after surgery.

The diet shifts in stages — liquid, then soft, then solid food. Protein is the priority, while high-calorie, fatty food is limited.

Pregnancy after bariatric surgery is possible, but doctors advise waiting at least 12–18 months. During this time the body stabilizes, weight reaches target values and nutritional status normalizes.

Yes, vitamins are essential after bariatric surgery. As digestive anatomy changes, the body absorbs certain nutrients less well, so regular vitamin and mineral supplements become a lasting 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.
