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
- Failure of previous attempts to lose weight by conventional means
Why don't diets and exercise work for everyone?
Plenty of people diet and exercise for years, only for the body to resist: a slower metabolism, a bigger appetite and the weight coming back. When diet changes and medication clearly cannot fundamentally improve matters on their own, the only effective option left is bariatric surgery.

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 used for a BMI of 35 to 45; average loss is 60–70% of excess weight.
Specifics: the outcome lasts less reliably than after bypass. Weight can come back if the diet is neglected, above all with high-calorie drinks and liquid food.
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: for a BMI over 45–50 with type 2 diabetes it is deemed the “gold standard”. Loss of excess weight is 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 operation is an improvement on the classic bypass. Compared with the standard technique, the surgeon creates a single connection (anastomosis) between the small stomach and the small intestine. Its simplicity makes it easier for the patient, with less recovery time.
Effectiveness: results comparable to classic Roux-en-Y bypass — up to 75–80% of excess weight lost.
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)
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: among the most powerful bariatric operations — excess weight loss reaches 80–90% with a lasting result.
Specifics: appetite drops because the smaller stomach no longer has its ghrelin-producing zone, and bypassing part of the intestine cuts calorie absorption. It fits super obesity (BMI over 50), severe type 2 diabetes, or serves as a second stage following 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
Each patient gets an individually chosen surgical method from our doctors. Before a decision, they look at your health, weight history and associated conditions to recommend the most fitting surgical treatment.
Support that stays in touch
After surgery, the team at City Medical Centre stays with you. For the entire first year, specialists keep track of your weight loss, oversee your tests and answer all questions about diet and recovery.
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
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 remains under observation at the clinic for 1 to 5 days, depending on the scope of surgery and related conditions.
Activity
Already in the first hours post-surgery you are allowed to sit up, stand and drink.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
You may get back to work 7–14 days post-surgery, depending on the physical load of your job.
Restrictions
No bathhouse, sauna or intense physical exercise during the first weeks.
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! Your recovery is overseen by City Medical Centre specialists, who offer psychological and medical support throughout each 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?
Modern laparoscopic technique is what we use. Just 4 small punctures of 5 to 15 mm are needed for the operation. Cosmetic sutures mean the marks are nearly invisible after healing.
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?
Four main types of bariatric surgery are performed at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each is selected individually based on BMI, related conditions and patient 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 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 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.
