Surgery is prescribed only when clear criteria are met
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.
Many people try various diets and exercise for years, but the body fights back: metabolism slows, appetite grows and the lost weight returns. When it becomes clear that diet changes and medication alone cannot fundamentally improve the situation, bariatric surgery becomes the only effective way out.

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: recommended for a BMI of 35 to 45. Typically patients shed 60–70% of 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
The surgeon shapes a small pouch, 50–70 ml, from the top of the stomach and routes it directly to the small intestine. Food intake drops and calorie absorption decreases as food covers a shorter distance in the gut.
Effectiveness: regarded as the “gold standard” for a BMI over 45–50 with type 2 diabetes. Loss of excess weight reaches 75–85%.
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: close to the classic Roux-en-Y bypass, with patients losing up to 75–80% of excess weight.
Specifics: surgery takes less time and recovery is faster. It can technically be reversed; the single anastomosis, though, poses a risk of bile reflux.

Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S combines the advantages of sleeve gastrectomy and intestinal bypass in one modern technique. It is done in two stages: stage one makes the stomach a narrow tube; stage two reroutes the small intestine so that most of it is excluded from active digestion.
Effectiveness: one of the most powerful bariatric operations — excess weight loss reaches 80–90% with a long-lasting result.
Specifics: with the ghrelin-producing zone removed, the smaller stomach reduces appetite; redirecting food past part of the intestine limits calorie uptake. Used for super obesity (BMI over 50), severe type 2 diabetes, or as a second stage when a sleeve was ineffective.

City Medical Centre takes a full-picture approach to obesity. Once the first examination is done, each patient gets a tailored diagnostic program (lab and instrumental) that reveals every disorder in the body.

A method matched to your goal
The surgical method is selected individually by our doctors for every patient. Your health, weight history and related conditions are reviewed first, so the most suitable surgical treatment can be offered.

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
The laparoscopic approach to bariatric operations at City Medical Centre greatly reduces recovery. Most patients are mobile on day one and return to everyday 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.
While recovery is largely individual, minimally invasive laparoscopic techniques keep rehab time as short as possible.

Duration
Patients stay under observation at the clinic 1 to 5 days, depending on how extensive the surgery is and related conditions.
Activity
In the first hours post-op, sitting up, standing and drinking fluids are fine.
Wound care
Absorbable sutures are used; they dissolve on their own.

Work
7–14 days after surgery you can return to work, depending on how physical the job is.
Restrictions
No sauna, no bathhouse and no intense physical exercise for the first weeks.
Diet
You follow a staged diet for 1–2 months, going from liquid to solid food as the stomach adapts.

Pace
With the specialists' advice followed, average loss is 10% of excess weight per month.
Stabilization
Full results are reached in 1.5–2 years. By then, stable eating habits are in place that prevent the weight from coming back.
Important! City Medical Centre specialists supervise your recovery and support you psychologically and medically at every stage of weight loss.

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?
Our surgeons use modern laparoscopic technique: the operation goes through 4 small 5 to 15 mm punctures. With cosmetic sutures, the marks become almost invisible once healed.
What diet do I need to follow?
Stage by stage, you move from liquid food to soft and then solid. Priority goes to protein, and 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?
Bariatric surgery does not rule out pregnancy, but doctors suggest waiting 12–18 months or more. During that time the body settles, weight reaches target values and nutrition status normalizes.
Do I need to take vitamins after surgery?
Yes, after bariatric surgery vitamins are a must. The altered digestive anatomy reduces absorption of some nutrients, which makes regular vitamin and mineral supplements a permanent 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.

Surgery is usually justified with a BMI above 40, or above 35 when serious related conditions are present, and sometimes at lower values if other approaches have failed. People in Boston who have carried 30 kg or more above normal for years, whose weight returns after every diet, or who live with type 2 diabetes, hypertension or joint pain are typical candidates.
Eating changes in stages. A staged diet lasts 1–2 months, moving from liquid to soft to solid food so the stomach can adapt, with the focus on protein and limited high-calorie, fatty dishes. Following specialist advice, patients lose on average 10% of excess weight per month. Those from Boston build stable eating habits that keep the weight from returning.
Everything needed for the result is combined in one package, with no hidden fees and no surprises. For patients from Boston, 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.
