Bariatric Surgery in Preston: Methods and Results

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 carry out 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.
• 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
• Previous tries at losing weight with ordinary methods have failed

BMI is the principal gauge of how advanced obesity is, found by dividing body weight (kg) by height squared (m²). Typically, a BMI above 40 — or above 35 with serious related conditions — justifies surgery. Some patients with lower values are considered for surgery too, if non-surgical options have failed.

Many people confuse the two, but their goals are fundamentally different. Bariatric surgery is a medical treatment for obesity and related diseases. It changes how the digestive tract works, addressing the causes of excess weight and metabolism. Plastic surgery reshapes the body's outer contours; it does not treat obesity or affect 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 time depends on the activity. Office work: after 2–4 weeks. Physical work: after 1.5 months. Sport and activity: swimming allowed after 30 days, other exercise gradually added as weight goes down. Travel and holidays: plan no sooner than one month after surgery.

Your meals progress in stages: liquid food, soft food, then solid. The stress is on protein and on reducing high-calorie, fatty food.

Pregnancy after bariatric surgery is possible, though doctors recommend waiting at least 12–18 months. In that time the body stabilizes, weight reaches its target and nutritional status returns to normal.

Yes, after bariatric surgery vitamins cannot be skipped. As the digestive anatomy changes, some nutrients are absorbed less well, making regular vitamin and mineral supplements a permanent feature 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.
