When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
BMI is the main tool for assessing the degree of obesity. It is calculated by dividing body weight (kg) by height squared (m²). Surgery is usually justified with a BMI above 40, or above 35 with serious related conditions. In some cases surgery is considered at lower values too — if non-surgical approaches have failed.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Failure of previous attempts to lose weight by conventional means
Why don't diets and exercise work for everyone?
Many people try various diets and exercise for years, but the body fights back: metabolism slows, appetite grows and the lost weight returns. When it becomes clear that diet changes and medication alone cannot fundamentally improve the situation, bariatric surgery becomes the only effective way out.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
During surgery the surgeon removes most of the stomach, turning it into a narrow tube. This greatly reduces portion size and lowers ghrelin, the hunger hormone, so the patient feels full much faster and eats less.
Effectiveness: the method suits a BMI of 35 to 45. On average patients lose 60–70% of their excess weight.
Specifics: the result is less durable than with bypass operations. If the diet is not followed, especially with high-calorie drinks and liquid food, the weight can return.
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 is considered the “gold standard” for a BMI over 45–50 with type 2 diabetes. Excess weight loss reaches 75–85%.
Specifics: the result lasts better than with other bariatric methods. Related conditions such as diabetes and hypertension often go into remission. Because the digestive anatomy changes, lifelong vitamin and mineral supplements are needed.
Mini gastric bypass (MGB)
This is an improved version of the classic bypass. Unlike the standard method, the surgeon creates only one connection (anastomosis) between the small stomach and the small intestine. The simpler technique is easier on the patient and needs less recovery time.
Effectiveness: comparable to the classic Roux-en-Y bypass — patients lose up to 75–80% of excess weight.
Specifics: shorter surgery and faster recovery. The procedure is technically reversible, but there is a risk of bile reflux due to the single anastomosis.
Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S is a modern combined technique that unites the benefits of sleeve gastrectomy and intestinal bypass. It is done in two stages: first the stomach is turned into a narrow tube, then the small intestine is rerouted so that most of it is excluded from active digestion.
Effectiveness: one of the most powerful bariatric operations — excess weight loss reaches 80–90% with a long-lasting result.
Specifics: a smaller stomach reduces appetite by removing the ghrelin-producing zone, and rerouting food past part of the intestine limits calorie absorption. It suits super obesity (BMI over 50), severe type 2 diabetes, or as a second stage after an ineffective sleeve.

City Medical Centre bariatric surgery centre
— your path
to confidence and harmony
City Medical Centre takes a comprehensive approach to obesity. After the first examination, each patient gets a personal diagnostic program (lab and instrumental) to identify 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
The City Medical Centre team stays with you after surgery. Throughout the first year, specialists track your weight loss, monitor your tests and answer all questions about diet and recovery.
Fast recovery
Bariatric operations at City Medical Centre are laparoscopic, which greatly shortens recovery. Most patients are up and moving on day one and return to normal life within a week.
Full diagnostics on site
No need to run between clinics. Our centre has everything for your work-up, from our own lab to ultrasound and gastroscopy. Preparation is quick, with no queues, all in one building.
Recovery after bariatric surgery
Recovery largely depends on the individual, but minimally invasive laparoscopic techniques keep rehabilitation as short as possible.
Duration
The patient stays under observation at the clinic for 1 to 5 days, depending on the extent of surgery and related conditions.
Activity
Within the first hours after surgery you may sit up, stand and drink fluids.
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
For the first weeks, no bathhouse, sauna or intense physical exercise.
Diet
A staged diet is prescribed for 1–2 months — from liquids to solids to let the stomach adapt.
Pace
Following the specialists' advice, patients lose on average 10% of excess weight per month.
Stabilization
The final result is reached in 1.5–2 years. By then the patient has built stable eating habits that prevent the weight from returning.
Important! Recovery is supervised by City Medical Centre specialists, who provide psychological and medical support at every stage of weight loss.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
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.
How soon can I return to work and normal life?
Will there be visible scars?
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.
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?
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.
Can I plan a pregnancy after surgery?
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.
Do I need to take vitamins after surgery?
Yes, vitamins after bariatric surgery are a must. Because the digestive anatomy changes, the body absorbs some nutrients less well, so regular vitamin and mineral supplements become a permanent part of the patient's life.
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.
