Surgery is prescribed only when clear criteria are met
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.
For years many try diet after diet and exercise, but the body pushes back — metabolism slows down, appetite increases and lost kilos return. When it is evident that diet changes and medication alone cannot fundamentally change the situation, bariatric surgery remains the only effective way out.

Sleeve gastrectomy
In surgery, most of the stomach is taken out and the rest is formed into a narrow tube. Portions become far smaller and ghrelin, the hormone behind hunger, drops, so the patient feels full quicker and eats less.
Effectiveness: works for a BMI from 35 to 45. On average, 60–70% of the excess weight is lost.
Specifics: the result holds up less well than after bypass operations. If the diet is broken, particularly with high-calorie drinks and liquid food, weight may come back.

Roux-en-Y gastric bypass
The surgeon creates a small 50–70 ml pouch at the top of the stomach and connects it directly to the small intestine. This limits food intake and reduces calorie absorption by shortening the path food travels through the gut.
Effectiveness: the operation counts as the “gold standard” for BMI above 45–50 with type 2 diabetes; 75–85% of excess weight is lost.
Specifics: outcomes are more durable than with other bariatric procedures. Diabetes, hypertension and other related conditions often go into remission. With the digestive anatomy changed, lifelong vitamin and mineral supplements are a must.

Mini gastric bypass (MGB)
An upgraded take on the classic bypass. In contrast to the standard method, only a single connection (anastomosis) is made between the small stomach and the small intestine. Being simpler, the technique is easier on the patient and shortens recovery.
Effectiveness: close to the classic Roux-en-Y bypass, with patients losing up to 75–80% of excess weight.
Specifics: less time in surgery and a faster recovery. Technically the procedure is reversible, though the single anastomosis brings a risk of bile reflux.

Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S, a modern combined technique, pairs the benefits of sleeve gastrectomy and intestinal bypass. It is carried out in two stages: the stomach is reshaped into a narrow tube, after which the small intestine is rerouted so most of it is bypassed in active digestion.
Effectiveness: a top-power bariatric operation — loss of excess weight reaches 80–90%, with a long-lasting result.
Specifics: a smaller stomach curbs appetite because the ghrelin-producing zone is removed, and sending food past part of the intestine limits calorie absorption. It suits super obesity (BMI over 50), severe type 2 diabetes, or a second stage after a sleeve that did not work.

City Medical Centre takes a full-picture approach to obesity. Once the first examination is done, each patient gets a tailored diagnostic program (lab and instrumental) that reveals every disorder in the body.

A method matched to your goal
Our doctors choose the surgical method individually for each patient. Before deciding, they review your health, weight history and related conditions to offer the most suitable surgical treatment.

Support that stays in touch
City Medical Centre's team stays with you once surgery is over. During the first year, specialists monitor your weight loss and test results and answer any questions on diet and recovery.

Fast recovery
At City Medical Centre bariatric surgery is laparoscopic, making recovery much shorter. Most patients are up and walking on the first day and resume normal life within a week.

Full diagnostics on site
No running from clinic to clinic. Our centre has everything for your work-up, from its own lab to ultrasound and gastroscopy. Preparation is fast, queue-free and all under one roof.
The pace of recovery is largely personal, but minimally invasive laparoscopic techniques shorten rehabilitation as much as possible.

Duration
Patients stay under observation at the clinic 1 to 5 days, depending on how extensive the surgery is and related conditions.
Activity
Sitting up, standing and drinking are allowed in the first hours after surgery.
Wound care
Absorbable sutures are used; they dissolve on their own.

Work
You can return to work 7–14 days after surgery, depending on how physical your job is.
Restrictions
No bathhouse, sauna or intense physical exercise during the first weeks.
Diet
For 1–2 months a staged diet is prescribed — liquids first, then solids — to help the stomach adapt.

Pace
With the specialists' advice followed, average loss is 10% of excess weight per month.
Stabilization
Reaching the final result takes 1.5–2 years. The patient has by then built steady eating habits that prevent weight from returning.
Important! Recovery is overseen by City Medical Centre specialists, with psychological and medical support at every step of weight loss.

Bariatric vs plastic surgery: what's the difference?
Many confuse the two, yet their purposes are fundamentally different. Bariatric surgery is medicine's treatment for obesity and related diseases: it changes how the digestive tract operates and addresses the causes of excess weight and metabolism. Plastic surgery reshapes outer contours of the body without treating obesity or affecting metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
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.
What diet do I need to follow?
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.
What types of bariatric surgery are there?
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.
Can I plan a pregnancy after surgery?
After bariatric surgery pregnancy is possible, yet doctors recommend at least 12–18 months of waiting. Meanwhile the body stabilizes, weight arrives at target values and nutritional status normalizes.
Do I need to take vitamins after surgery?
Yes, vitamins become essential after bariatric surgery. The changed digestive anatomy lowers absorption of some nutrients, so regular vitamin and mineral supplements turn into a permanent part of the patient's life.
Can the weight come back?
Regaining weight after bariatric surgery is possible, yet very unlikely when you stick to the doctor's advice. The keys are proper nutrition, no high-calorie drinks and regular check-ups with City Medical Centre specialists.
