Surgery is prescribed only when clear criteria are met
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.
Years of various diets and workouts often end the same way: the body fights back, metabolism slows, appetite grows and the weight returns. If it becomes clear that medication and dietary changes alone cannot fundamentally improve the situation, bariatric surgery is the only effective way forward.

Sleeve gastrectomy
Here the surgeon removes most of the stomach, reshaping it into a narrow tube. That greatly limits portion size and lowers ghrelin, the hunger hormone — the patient feels full much more quickly and eats less.
Effectiveness: suitable for a BMI of 35 to 45. Patients lose 60–70% of their excess weight on average.
Specifics: compared with bypass operations, the result is less stable. When the diet is not followed — notably with high-calorie drinks and liquid food — weight may return.

Roux-en-Y gastric bypass
The operation creates a small 50–70 ml stomach pouch at the top and connects it directly with the small intestine. Less food can be taken in, and fewer calories are absorbed because the path through the gut is shorter.
Effectiveness: viewed as the “gold standard” for BMI over 45–50 plus type 2 diabetes. It removes 75–85% of excess weight.
Specifics: more lasting results than other bariatric methods. Associated conditions such as diabetes and hypertension often go into remission. Because digestion is anatomically altered, vitamins and minerals must be taken for life.

Mini gastric bypass (MGB)
The classic bypass, improved. Unlike the standard method, the surgeon forms just one connection (anastomosis) between the small stomach and the small intestine. A simpler technique puts less strain on the patient and cuts the time needed to recover.
Effectiveness: equal to the classic Roux-en-Y bypass — up to 75–80% of excess weight is shed.
Specifics: surgery takes less time and recovery is faster. It can technically be reversed; the single anastomosis, though, poses a risk of bile reflux.

Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S is an up-to-date combined technique joining the strengths of sleeve gastrectomy and intestinal bypass. There are two stages: the stomach is first made into a narrow tube, and then the small intestine is rerouted to exclude most of it from active digestion.
Effectiveness: one of the most powerful bariatric operations — excess weight loss reaches 80–90% with a long-lasting result.
Specifics: appetite falls as the smaller stomach loses the zone that produces ghrelin, while food rerouted around part of the intestine yields fewer absorbed calories. Right for super obesity (BMI over 50), severe type 2 diabetes, or as a second stage after an ineffective sleeve.

City Medical Centre sees obesity comprehensively. From the first examination, each patient has a personal diagnostic program (lab and instrumental) built to identify every disorder present in the body.

A method matched to your goal
Each patient gets an individually chosen surgical method from our doctors. Before a decision, they look at your health, weight history and associated conditions to recommend the most fitting 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
City Medical Centre performs bariatric operations laparoscopically, which shortens recovery considerably. Most patients are on their feet on day one and back to normal life within a week.

Full diagnostics on site
No shuttling between clinics. Your full work-up happens at our centre, from our own lab to ultrasound and gastroscopy. Preparation is quick, there are no queues, and it is all in one building.
Each patient recovers differently, but minimally invasive laparoscopic techniques keep rehabilitation as brief as possible.

Duration
The patient is monitored at the clinic for 1 to 5 days, according to the extent of surgery and any related conditions.
Activity
Soon after surgery — within the first hours — you may sit up, stand and take fluids.
Wound care
Absorbable sutures are used; they dissolve on their own.

Work
Back to work in 7–14 days after surgery, depending on how physical your job happens to be.
Restrictions
During the first weeks, stay away from bathhouses, saunas and intense exercise.
Diet
A staged diet is prescribed for 1–2 months, moving from liquids to solids so the stomach can adapt.

Pace
By following the specialists' advice, patients lose 10% of excess weight per month on average.
Stabilization
The final outcome arrives within 1.5–2 years. By this time the patient has lasting eating habits that stop the weight returning.
Important! City Medical Centre specialists keep recovery under supervision and give psychological and medical support at every stage of losing weight.

Bariatric vs plastic surgery: what's the difference?
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.
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 in stages: from liquid food to soft, then to solid. The focus is on protein and on limiting high-calorie, fatty food.
What types of bariatric surgery are there?
There are four main types of bariatric surgery at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. BMI, related conditions and the patient's goals guide the individual choice of method.
Can I plan a pregnancy after surgery?
It is possible to get pregnant after bariatric surgery, but doctors recommend a minimum wait of 12–18 months. During it the body stabilizes, weight reaches its target and nutritional status is normalized.
Do I need to take vitamins after surgery?
Yes, taking vitamins after bariatric surgery is mandatory. Because digestion is anatomically altered, the body absorbs some nutrients poorly, so regular vitamin and mineral supplements stay in the patient's life permanently.
Can the weight come back?
Weight regain after bariatric surgery is possible, but very unlikely if you follow the doctor's advice. Proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are key.
