When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
To gauge obesity, doctors rely primarily on BMI, which equals body weight (kg) divided by the square of height (m²). An operation is usually warranted with a BMI over 40, or over 35 with serious associated conditions. Occasionally surgery is weighed at lower values as well, once non-surgical options have failed.
Key factors
- 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
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
The surgeon takes out most of the stomach and shapes the rest into a narrow tube. Portion size shrinks sharply and ghrelin, the hunger hormone, drops, so fullness comes much faster and the patient eats less.
Effectiveness: the method suits a BMI of 35 to 45. On average patients lose 60–70% of their excess weight.
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 surgeon forms a small 50–70 ml pouch at the top of the stomach and joins it straight to the small intestine. This restricts food intake and cuts calorie absorption by shortening the route food takes through the gut.
Effectiveness: this operation is seen as the “gold standard” with a BMI above 45–50 and type 2 diabetes. Excess weight falls by up to 75–85%.
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: in line with the classic Roux-en-Y bypass — loss of 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 is a contemporary combined technique uniting what is best in sleeve gastrectomy and intestinal bypass. Two stages are involved: first a narrow tube is formed from the stomach, then the small intestine is rerouted, leaving most of it outside active digestion.
Effectiveness: one of the most potent bariatric operations; excess weight loss hits 80–90% and the result is long-lasting.
Specifics: the reduced stomach lowers appetite once the ghrelin-producing zone is removed, and routing food past a section of intestine limits how many calories are absorbed. Suitable for 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 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 decide on the surgical method case by case. Before choosing, they evaluate your health, weight history and related conditions in order to offer the surgical treatment that fits best.
Support that stays in touch
Once the operation is done, the City Medical Centre team stays alongside you. Throughout the first year specialists follow your weight loss, review tests and answer all questions on diet and recovery.
Fast recovery
Laparoscopic bariatric operations at City Medical Centre make recovery far shorter. Most patients are moving on day one and resume their normal life within a week.
Full diagnostics on site
Forget going between clinics. Everything for your work-up is here, including our own lab, ultrasound and gastroscopy. Preparation is quick and queue-free, all in a single building.
Recovery after bariatric surgery
Each patient recovers differently, but minimally invasive laparoscopic techniques keep rehabilitation as brief as possible.
Duration
The length of clinic observation is 1 to 5 days, depending on the extent of the operation and related conditions.
Activity
Within hours of surgery, you can sit up, get on your feet and drink 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
The first weeks exclude bathhouse, sauna and intense physical exercise.
Diet
A staged diet is prescribed for 1–2 months — from liquids to solids to let the stomach adapt.
Pace
When they follow specialist advice, patients lose an average of 10% of excess weight each month.
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! Specialists at City Medical Centre supervise recovery, providing medical and psychological support across every stage of weight loss.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
It is common to confuse them, but their goals are fundamentally different. Bariatric surgery treats obesity and related diseases medically. By changing how the digestive tract works, it addresses the causes of excess weight and metabolism. Plastic surgery shapes the body's outer contours; it does not treat obesity and has no effect on metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
Modern laparoscopic technique allows the operation through 4 small punctures of 5 to 15 mm. Cosmetic sutures make the marks almost invisible when fully healed.
What diet do I need to follow?
In stages, your diet goes from liquid to soft to solid food. The main focus is protein and restricting 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?
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 necessary. The body absorbs certain nutrients less well due to the changed digestive anatomy, so regular vitamin and mineral supplements become a permanent part of the patient's life.
Can the weight come back?
Weight may return after bariatric surgery, though that is very unlikely when you follow the doctor's advice. Key factors: proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists.
