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
- Past attempts to shed weight in conventional ways were unsuccessful
Why don't diets and exercise work for everyone?
It is common to try various diets and exercise for years while the body resists — slower metabolism, stronger appetite, returning weight. When it becomes evident that diet changes and medication by themselves cannot fundamentally help, bariatric surgery becomes the only effective solution.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
Most of the stomach is removed during surgery, and what remains becomes a narrow tube. This cuts portion size significantly and reduces ghrelin, the hormone of hunger, so patients feel full sooner and eat less.
Effectiveness: the method is appropriate for a BMI of 35 to 45. Average loss of excess weight is 60–70%.
Specifics: bypass operations give a more durable result. Should the diet be ignored, especially with high-calorie drinks and liquid food, weight can 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: 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: 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)
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 with the classic Roux-en-Y bypass: patients drop up to 75–80% of excess weight.
Specifics: shorter operating time and faster recovery. Though technically reversible, it carries a risk of bile reflux due to the single anastomosis.
Single anastomosis duodeno-ileal bypass (SADI-S)
The modern combined technique SADI-S unites the benefits of sleeve gastrectomy and intestinal bypass. It proceeds in two stages: the surgeon first turns the stomach into a narrow tube, then reroutes the small intestine so that most of it is kept out of active digestion.
Effectiveness: a top-power bariatric operation — loss of excess weight reaches 80–90%, with a long-lasting result.
Specifics: the smaller stomach, minus its ghrelin-producing zone, dampens appetite, and bypassing a portion of the intestine limits calorie absorption. It is an option in super obesity (BMI over 50), severe type 2 diabetes, or as a second stage after an ineffective sleeve.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
These two are frequently confused, although their goals differ at the core. Bariatric surgery is a medical treatment of obesity and related diseases that changes the workings of the digestive tract, targeting the causes of excess weight and metabolism. Plastic surgery corrects outer body contours; it does not treat obesity or change metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
Our surgeons use modern laparoscopic technique: the operation goes through 4 small 5 to 15 mm punctures. With cosmetic sutures, the marks become almost invisible once healed.
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?
Four main bariatric surgery types are available at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. The method is picked individually, considering BMI, related conditions and the patient's goals.
Can I plan a pregnancy after surgery?
Pregnancy is an option after bariatric surgery, but doctors advise waiting at least 12–18 months. By then the body has stabilized, weight has reached target values and nutritional status has 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 can come back after bariatric surgery, but this is very unlikely if you follow your doctor's advice. Proper nutrition, skipping high-calorie drinks and regular follow-up with City Medical Centre specialists are key.
