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
- Conventional weight-loss methods have failed in past attempts
Why don't diets and exercise work for everyone?
Many try all kinds of diets and exercise for years, yet the body defends itself — metabolism drops, hunger grows and lost weight returns. Once it is obvious that medication and a changed diet alone cannot fundamentally fix the situation, bariatric surgery becomes the only effective path.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
During surgery the surgeon removes most of the stomach, turning it into a narrow tube. This greatly reduces portion size and lowers ghrelin, the hunger hormone, so the patient feels full much faster and eats less.
Effectiveness: the method fits a BMI between 35 and 45. Average loss is 60–70% of excess weight.
Specifics: the result is less durable than with bypass operations. If the diet is not followed, especially with high-calorie drinks and liquid food, the weight can return.
Roux-en-Y gastric bypass
The surgeon creates a small 50–70 ml pouch at the top of the stomach and connects it directly to the small intestine. This limits food intake and reduces calorie absorption by shortening the path food travels through the gut.
Effectiveness: considered the “gold standard” when BMI exceeds 45–50 with type 2 diabetes. Patients lose 75–85% of excess weight.
Specifics: the result endures better than with alternative bariatric methods. Associated diabetes and hypertension frequently go into remission. Lifelong vitamin and mineral supplements are required because the digestive anatomy changes.
Mini gastric bypass (MGB)
An advanced version of the classic bypass. Differing from the standard method, it involves only one connection (anastomosis) from the small stomach to the small intestine. The simpler technique is gentler on patients and needs a shorter recovery period.
Effectiveness: matches the classic Roux-en-Y bypass — patients' excess weight loss is up to 75–80%.
Specifics: shorter surgery, quicker recovery. It is technically reversible, yet bile reflux is a risk because of the single anastomosis.
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 most powerful options in bariatric surgery: excess weight loss of 80–90%, lasting a long time.
Specifics: removing the ghrelin-producing zone makes the stomach smaller and lowers appetite, while rerouting food around part of the intestine restricts calorie absorption. Indicated 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 handles obesity comprehensively. After the first exam, every patient gets an individual diagnostic program (lab plus instrumental) designed to pinpoint every disorder in the body.
A method matched to your goal
Our doctors decide on the surgical method case by case. Before choosing, they evaluate your health, weight history and related conditions in order to offer the surgical treatment that fits best.
Support that stays in touch
The City Medical Centre team keeps supporting you after the operation. All through the first year, specialists track how your weight drops, check your tests and handle every question on diet and recovery.
Fast recovery
At City Medical Centre, bariatric operations are laparoscopic, which significantly shortens recovery. Most patients are up and active on day one 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
Each patient recovers differently, but minimally invasive laparoscopic techniques keep rehabilitation as brief 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
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 bathhouse, sauna or intense physical exercise during the first weeks.
Diet
You follow a staged diet for 1–2 months, going from liquid to solid food as the stomach adapts.
Pace
By following the specialists' advice, patients lose 10% of excess weight per month on average.
Stabilization
The end result is achieved in 1.5–2 years, when the patient already has stable eating habits that prevent weight regain.
Important! Recovery takes place under the supervision of City Medical Centre specialists, who give psychological and medical support at all weight-loss stages.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
These two are frequently confused, although their goals differ at the core. Bariatric surgery is a medical treatment of obesity and related diseases that changes the workings of the digestive tract, targeting the causes of excess weight and metabolism. Plastic surgery corrects outer body contours; it does not treat obesity or change metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
We use modern laparoscopic technique. The operation is done through 4 small punctures of 5 to 15 mm. Cosmetic sutures are placed, so once healed the marks become almost invisible.
What diet do I need to follow?
You move through diet stages from liquid food to soft and finally solid. Protein comes first, and high-calorie, fatty food is restricted.
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?
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 after bariatric surgery are a must. Because the digestive anatomy changes, the body absorbs some nutrients less well, so regular vitamin and mineral supplements become a permanent part of the patient's life.
Can the weight come back?
After bariatric surgery weight regain can happen, but it is very unlikely if the doctor's advice is followed. What matters is proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists.

Choosing a bariatric method in Berlin
All bariatric operations here are laparoscopic, performed through four small punctures of 5 to 15 mm with cosmetic sutures, so the marks become almost invisible after healing. This greatly shortens recovery. For those from Berlin, the choice between sleeve, classic bypass, mini bypass and SADI-S depends on BMI, related diseases and the result you want to reach.
During the operation the surgeon works laparoscopically, which keeps rehabilitation as short as possible. Right after, you are under round-the-clock care in a ward, with meals and nursing included. After discharge, most people in Berlin return to their normal routine within a week, following a diet plan and avoiding saunas and heavy exercise for the first weeks.
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 Berlin leave a request on the page or message the clinic, then receive a free consultation with a bariatric surgeon.
