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
- Weight-loss attempts using conventional methods have not succeeded
Why don't diets and exercise work for everyone?
Years of various diets and workouts often end the same way: the body fights back, metabolism slows, appetite grows and the weight returns. If it becomes clear that medication and dietary changes alone cannot fundamentally improve the situation, bariatric surgery is the only effective way forward.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
During the procedure the surgeon removes the greater part of the stomach, forming a narrow tube. Portions get far smaller and ghrelin, the hunger hormone, decreases, so the patient is satisfied 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: less durable results than bypass operations. Without sticking to the diet, especially avoiding high-calorie drinks and liquid food, the weight may return.
Roux-en-Y gastric bypass
A 50–70 ml pouch is formed at the upper end of the stomach and linked directly to the small intestine. It limits food intake and lowers calorie absorption because food moves along a shorter stretch of 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: 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: in line with the classic Roux-en-Y bypass — loss of up to 75–80% of excess weight.
Specifics: a faster operation and shorter recovery. The procedure can be undone technically, but there is a bile reflux risk from the single anastomosis.
Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S is an up-to-date combined technique joining the strengths of sleeve gastrectomy and intestinal bypass. There are two stages: the stomach is first made into a narrow tube, and then the small intestine is rerouted to exclude most of it from active digestion.
Effectiveness: one of the strongest bariatric procedures, with 80–90% excess weight loss and a long-lasting result.
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 treats obesity comprehensively. Following the first examination, every patient receives a personal diagnostic program (lab and instrumental) to detect every disorder in the body.
A method matched to your goal
Our doctors tailor the choice of surgical method to each patient. Ahead of the decision they study your health, weight history and related conditions to offer the best-suited surgical treatment.
Support that stays in touch
City Medical Centre's team stays with you once surgery is over. During the first year, specialists monitor your weight loss and test results and answer any questions on diet and recovery.
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
You won't need to visit several clinics. Our centre covers the whole work-up, from our in-house lab to ultrasound and gastroscopy. Quick preparation with no queues, all in one building.
Recovery after bariatric surgery
Recovery is mostly down to the individual; still, minimally invasive laparoscopic methods keep rehabilitation 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
Sitting up, standing and drinking are allowed in the first hours after surgery.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
You can return to work 7–14 days after surgery, depending on how physical your job is.
Restrictions
For the first few weeks, skip the bathhouse, sauna and intense exercise.
Diet
A staged diet is prescribed for 1–2 months, moving from liquids to solids so the stomach can adapt.
Pace
Keeping to the specialists' advice, patients lose 10% of their excess weight monthly on average.
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 supervise your recovery and support you psychologically and medically at every stage of weight loss.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
The two are often mistaken for each other, but their goals are fundamentally different. Bariatric surgery provides medical treatment for obesity and related diseases. Changing how the digestive tract works, it deals with the causes of excess weight and metabolism. Plastic surgery modifies 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?
Using modern laparoscopic technique, we perform the operation via 4 small punctures of 5 to 15 mm. Cosmetic sutures are placed, leaving marks that are nearly invisible after healing.
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?
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?
Pregnancy after bariatric surgery can happen, though doctors advise holding off at least 12–18 months. In this period the body becomes stable, weight reaches target values and nutritional status normalizes.
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 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.

Everything about bariatric surgery for Stockholm patients
The decision rests on clear criteria: body mass index, overall health with related chronic conditions, and failed previous attempts at weight loss. BMI is weight in kilograms divided by height in metres squared. Contraindications include acute illness, severe chronic or mental illness, and less than six months since breastfeeding ended. Stockholm patients receive a personal assessment against these points.
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 Stockholm.
Everything needed for the result is combined in one package, with no hidden fees and no surprises. For patients from Stockholm, 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.
