When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
The main way to assess the degree of obesity is BMI. It is body weight (kg) divided by height squared (m²). Generally, surgery is justified with BMI above 40, or above 35 combined with serious related conditions. Lower values may sometimes be considered for surgery too, when non-surgical measures have failed.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Standard approaches to weight loss have not worked before
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
In the operation the surgeon removes most of the stomach, leaving a narrow tube. Portions become much smaller and levels of ghrelin, the hunger hormone, fall, so the patient feels full far sooner and eats less.
Effectiveness: the method fits a BMI between 35 and 45. Average loss is 60–70% of excess weight.
Specifics: the effect is less durable than with bypass procedures. Ignoring the diet, especially high-calorie drinks and liquid meals, may bring the weight back.
Roux-en-Y gastric bypass
The surgeon builds a 50–70 ml pouch in the upper part of the stomach and attaches it directly to the small intestine. This caps food intake and lowers calorie absorption by shortening food's route through the gut.
Effectiveness: the operation counts as the “gold standard” for BMI above 45–50 with type 2 diabetes; 75–85% of excess weight is lost.
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)
A modified version of the classic bypass. Unlike the standard operation, just one connection (anastomosis) joins the small stomach and the small intestine. The technique is simpler, so it is easier on the patient and recovery takes less time.
Effectiveness: in line with the classic Roux-en-Y bypass — loss of up to 75–80% of excess weight.
Specifics: the operation is shorter and recovery faster. Reversal is technically possible, but a single anastomosis means a risk of bile reflux.
Single anastomosis duodeno-ileal bypass (SADI-S)
As a modern combined technique, SADI-S brings together the benefits of sleeve gastrectomy and intestinal bypass. Its two stages: making the stomach into a narrow tube, then rerouting the small intestine so the majority of it is excluded from active digestion.
Effectiveness: one of the strongest bariatric procedures, with 80–90% excess weight loss and a long-lasting result.
Specifics: removal of the ghrelin-producing zone shrinks the stomach and appetite, and routing food past part of the intestine curbs calorie absorption. Appropriate for super obesity (BMI over 50), severe type 2 diabetes, or as a second stage after a sleeve that failed.

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 City Medical Centre team continues to support you. Throughout year one, specialists track weight loss, review your tests and answer all your questions on diet and recovery.
Fast recovery
Bariatric operations at City Medical Centre are laparoscopic, which greatly shortens recovery. Most patients are up and moving on day one and return to normal life within a week.
Full diagnostics on site
No shuttling between clinics. Your full work-up happens at our centre, from our own lab to ultrasound and gastroscopy. Preparation is quick, there are no queues, and it is all in one building.
Recovery after bariatric surgery
Recovery depends heavily on the individual, but minimally invasive laparoscopic methods keep rehabilitation as short as possible.
Duration
The patient is monitored at the clinic for 1 to 5 days, according to the extent of surgery and any 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
You may get back to work 7–14 days post-surgery, depending on the physical load of your job.
Restrictions
Bathhouse, sauna and intense physical exercise are banned in early weeks.
Diet
A staged diet is prescribed for 1–2 months — from liquids to solids to let the stomach adapt.
Pace
Patients sticking to the specialists' advice shed on average 10% of excess weight per 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! Your recovery is supervised by City Medical Centre specialists, who give psychological and medical support through each stage of weight loss.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
People often confuse these two, though their aims are fundamentally different. Bariatric surgery is medical treatment of obesity and associated diseases. It changes the way the digestive tract works, acting on the causes of excess weight and on metabolism. Plastic surgery alters outer body contours and does not treat obesity or affect 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 shifts in stages — liquid, then soft, then solid food. Protein is the priority, while high-calorie, fatty food is limited.
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 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, 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 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.

Everything about bariatric surgery for Belgrade patients
Sleeve gastrectomy turns most of the stomach into a narrow tube, reducing portion size and levels of ghrelin, the hunger hormone. It suits a BMI of 35 to 45, with patients losing on average 60–70% of excess weight. For anyone from Belgrade with a higher BMI or type 2 diabetes, a bypass may fit better; the surgeon compares options at the consultation.
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 Belgrade.
Everything needed for the result is combined in one package, with no hidden fees and no surprises. For patients from Belgrade, it includes surgery by a dedicated team, round-the-clock care in the ward with meals and nursing, a doctor nearby 24/7 and a personal coordinator. The first step is a free 15-minute consultation with a bariatric surgeon.
