When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
BMI is the principal gauge of how advanced obesity is, found by dividing body weight (kg) by height squared (m²). Typically, a BMI above 40 — or above 35 with serious related conditions — justifies surgery. Some patients with lower values are considered for surgery too, if non-surgical options 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?
Many people spend years on different diets and exercise, yet the body resists: metabolism slows, appetite rises and the lost weight comes back. Once it is clear that changing the diet and taking medication cannot fundamentally improve things, bariatric surgery becomes the only effective solution.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
The surgeon removes the larger part of the stomach so it becomes a narrow tube. This strongly reduces how much fits in a portion and lowers ghrelin, the hunger hormone; the patient feels full faster and eats less.
Effectiveness: the method is intended for a BMI of 35 to 45. Excess weight goes down by 60–70% 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
Using the top of the stomach, the surgeon creates a small 50–70 ml pouch joined directly to the small intestine. This limits intake and reduces the calories absorbed by cutting short the journey of food through the gut.
Effectiveness: viewed as the “gold standard” for BMI over 45–50 plus type 2 diabetes. It removes 75–85% of excess weight.
Specifics: results last better than after other bariatric methods. Related conditions — diabetes, hypertension — often go into remission. The digestive anatomy is changed, so vitamin and mineral supplements are needed throughout life.
Mini gastric bypass (MGB)
This is an enhanced form of the classic bypass. The standard method differs: here the surgeon makes only one connection (anastomosis) between the small stomach and the small intestine. Thanks to the simpler technique, the patient has an easier time and recovers faster.
Effectiveness: matches the classic Roux-en-Y bypass — patients' excess weight loss is up to 75–80%.
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: ranks among the most powerful bariatric operations: up to 80–90% of excess weight lost, with lasting results.
Specifics: removing the ghrelin-producing zone makes the stomach smaller and lowers appetite, while rerouting food around part of the intestine restricts calorie absorption. Indicated 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 approaches obesity in a comprehensive way. Each patient, after the first examination, is assigned a personal diagnostic program (lab and instrumental) to identify all disorders 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 is with you after surgery too. For the full first year, specialists track weight loss, keep an eye on your tests and answer every diet and recovery question.
Fast recovery
All bariatric operations at City Medical Centre are laparoscopic, which greatly speeds recovery. Most patients get up and move on the first day and return to normal life within a week.
Full diagnostics on site
No need to travel between clinics. From our own lab to ultrasound and gastroscopy, the centre has all you need for your work-up. Preparation is fast, without queues, in one building.
Recovery after bariatric surgery
How recovery goes is largely individual, yet minimally invasive laparoscopic techniques keep the rehabilitation period to a minimum.
Duration
The patient remains under observation at the clinic for 1 to 5 days, depending on the scope 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
Work can be resumed 7–14 days after surgery, depending on how physically demanding it is.
Restrictions
For the first few weeks, skip the bathhouse, sauna and intense exercise.
Diet
Doctors prescribe a staged diet for 1–2 months, from liquids through to solids, for the stomach to adapt.
Pace
On average, patients who follow the specialists' advice lose 10% of excess weight a month.
Stabilization
In 1.5–2 years the final result is reached, and by then the patient's stable eating habits prevent the weight coming back.
Important! City Medical Centre specialists oversee recovery, offering 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?
Though often confused, the two have fundamentally different goals. Bariatric surgery is a medical treatment of obesity and related illnesses; it changes the functioning of the digestive tract to address the causes of excess weight and metabolism. Plastic surgery reshapes the outer contours of the body and neither treats obesity nor affects metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
We apply modern laparoscopic technique, operating through 4 small punctures of 5 to 15 mm. Thanks to cosmetic sutures, the marks are almost invisible once they heal.
What diet do I need to follow?
You move through diet stages from liquid food to soft and finally solid. Protein comes first, and high-calorie, fatty food is restricted.
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?
Getting pregnant after bariatric surgery is possible, but doctors advise waiting at least 12–18 months, so the body can stabilize, weight can reach target values and nutritional status can normalize.
Do I need to take vitamins after surgery?
Yes — vitamins are required after bariatric surgery. With the digestive anatomy changed, some nutrients are absorbed less well, and regular vitamin and mineral supplements become a permanent part of life.
Can the weight come back?
Weight regain is possible after bariatric surgery but very unlikely provided you follow the doctor's advice. Eat properly, avoid high-calorie drinks and keep up regular follow-up with City Medical Centre specialists.

Choosing a bariatric method in Budapest
Bariatric surgery is a medical treatment for obesity and related diseases. Unlike plastic surgery, it changes how the digestive tract works and addresses the causes of excess weight. For patients from Budapest, four main methods are available: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass and SADI-S. Each is chosen individually based on BMI, related conditions and personal goals.
A personal coordinator is assigned from day one, so no one goes through the process alone. After the first examination, each patient gets an individual diagnostic programme to identify every disorder in the body. Then the surgeon selects the method and performs the laparoscopic operation, and a doctor stays nearby 24/7. That is the sequence for everyone from Budapest.
A permanent team — not a duty shift — handles your case, and the whole package is transparent. Included are the operation, 24/7 care in the ward, meals, nursing and a personal coordinator from day one, plus support throughout the first year. Budapest patients also get a contractual result guarantee. Book a free consultation to discuss your situation.
