When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
BMI is the key measure used to assess how severe obesity is. You get it by dividing body weight (kg) by height squared (m²). Surgery is generally justified at a BMI above 40, or above 35 when serious related conditions are present. Sometimes it is also considered at lower values — when non-surgical methods have not worked.
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 spend years on diets and exercise, and the body fights them all the way: metabolism slows, appetite grows, the lost kilos come back. As soon as it is clear that medication and diet changes alone cannot fundamentally improve the situation, bariatric surgery is the only effective way out.

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 suits a BMI of 35 to 45. On average patients lose 60–70% of their excess weight.
Specifics: results are less lasting than with bypass surgery. Weight can return if the diet is not kept, especially with high-calorie drinks and liquid foods.
Roux-en-Y gastric bypass
A small upper-stomach pouch of 50–70 ml is made and connected straight to the small intestine. It restricts how much food is eaten and reduces calorie uptake, as food follows a shorter path through the intestine.
Effectiveness: the “gold standard” for patients with a BMI over 45–50 and type 2 diabetes. Up to 75–85% of excess weight is lost.
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: matches the classic Roux-en-Y bypass — patients' excess weight loss is up to 75–80%.
Specifics: quicker surgery and a speedier recovery. The procedure is technically reversible; however, the single anastomosis creates a bile reflux risk.
Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S is a modern combination technique that draws on the benefits of both sleeve gastrectomy and intestinal bypass. In two stages, the stomach is first converted into a narrow tube and the small intestine is then rerouted to exclude its greater part from 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 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
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
At City Medical Centre bariatric surgery is laparoscopic, making recovery much shorter. Most patients are up and walking on the first day and resume normal life within a week.
Full diagnostics on site
Running around different clinics is not necessary. Our centre has all you need for your work-up, from our lab to ultrasound and gastroscopy. Preparation is fast and queue-free, in one building.
Recovery after bariatric surgery
While recovery is largely individual, minimally invasive laparoscopic techniques keep rehab time as short as possible.
Duration
The patient is kept under clinic observation for 1 to 5 days, depending on the scale of surgery and related conditions.
Activity
In the early hours after surgery you can already sit up, stand and have 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
In the first weeks, avoid the bathhouse, sauna and intense physical exercise.
Diet
A staged diet is prescribed for 1–2 months, moving from liquids to solids so the stomach can adapt.
Pace
When they follow specialist advice, patients lose an average of 10% of excess weight each month.
Stabilization
It takes 1.5–2 years to reach the final result. By then, the patient has formed steady eating habits that keep weight from coming back.
Important! City Medical Centre specialists keep recovery under supervision and give psychological and medical support at every stage of losing weight.

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?
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?
The diet evolves in steps — from liquids to soft, then solid food — with a focus on protein and limits on 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?
You can become pregnant after bariatric surgery, but doctors advise a wait of at least 12–18 months. Over this period the body stabilizes, weight hits target values and nutritional status normalizes.
Do I need to take vitamins after surgery?
Yes, vitamins are essential after bariatric surgery. As digestive anatomy changes, the body absorbs certain nutrients less well, so regular vitamin and mineral supplements become a lasting part of the patient's life.
Can the weight come back?
Weight can be regained after bariatric surgery, but this is very unlikely with the doctor's advice followed. Proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are crucial.

Bariatric surgery in Prague: methods, stages and package
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 Prague, 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.
Preparation is practical. Two to four weeks before surgery, cut fast carbohydrates and fats; a month before, quit smoking, reduce physical activity and avoid stress. The day before, switch to light meals, with the last light meal in the evening and last fluids 3–4 hours before the operation. The same plan applies to everyone preparing for bariatric surgery in Prague.
Weight loss is written into the contract, and the package includes every stage: consultation, diagnostics, the operation, inpatient care with meals and a year of support. A personal coordinator guides you from day one. To begin, patients from Prague leave a request on the page or message the clinic, then receive a free consultation with a bariatric surgeon.
