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
- No success with earlier tries to slim down by usual means
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
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 fits a BMI between 35 and 45. Average loss is 60–70% of excess weight.
Specifics: bypass operations give a more durable result. Should the diet be ignored, especially with high-calorie drinks and liquid food, weight can return.
Roux-en-Y gastric bypass
A small upper-stomach pouch of 50–70 ml is made and connected straight to the small intestine. It restricts how much food is eaten and reduces calorie uptake, as food follows a shorter path through the intestine.
Effectiveness: regarded as the “gold standard” for a BMI over 45–50 with type 2 diabetes. Loss of excess weight reaches 75–85%.
Specifics: longer-lasting than other bariatric methods. Conditions such as diabetes and hypertension often go into remission. Since the anatomy of digestion is altered, patients need vitamin and mineral supplements for life.
Mini gastric bypass (MGB)
An upgraded take on the classic bypass. In contrast to the standard method, only a single connection (anastomosis) is made between the small stomach and the small intestine. Being simpler, the technique is easier on the patient and shortens recovery.
Effectiveness: on par with the classic Roux-en-Y bypass — patients shed 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)
SADI-S is a contemporary combined technique uniting what is best in sleeve gastrectomy and intestinal bypass. Two stages are involved: first a narrow tube is formed from the stomach, then the small intestine is rerouted, leaving most of it outside active digestion.
Effectiveness: one of the most powerful options in bariatric surgery: excess weight loss of 80–90%, lasting a long time.
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.

— your path
to confidence and harmony
City Medical Centre takes a comprehensive approach to obesity. After the first examination, each patient gets a personal diagnostic program (lab and instrumental) to identify 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 remains by your side after surgery. For the whole first year, specialists follow your weight loss, check your tests and answer every question about 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
Forget going between clinics. Everything for your work-up is here, including our own lab, ultrasound and gastroscopy. Preparation is quick and queue-free, all in a single building.
Recovery after bariatric surgery
Recovery varies from person to person, but minimally invasive laparoscopic techniques make rehabilitation as short as it can be.
Duration
Observation at the clinic lasts 1 to 5 days, based on how extensive the surgery is and on related conditions.
Activity
In the first hours after the operation you can sit up, stand and drink fluids.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
You can go back to work 7–14 days after surgery, depending on how physical the job is.
Restrictions
Bathhouse, sauna and intense workouts are off-limits for the first weeks.
Diet
A staged diet is prescribed for 1–2 months — from liquids to solids to let the stomach adapt.
Pace
With the specialists' advice followed, average loss is 10% of excess weight per month.
Stabilization
Reaching the final result takes 1.5–2 years. The patient has by then built steady eating habits that prevent weight from returning.
Important! Specialists at City Medical Centre supervise recovery, providing medical and psychological support across every stage of weight loss.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
It is common to confuse them, but their goals are fundamentally different. Bariatric surgery treats obesity and related diseases medically. By changing how the digestive tract works, it addresses the causes of excess weight and metabolism. Plastic surgery shapes the body's outer contours; it does not treat obesity and has no effect on 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?
Your diet changes step by step: from liquid food to soft and then to solid. The emphasis is on protein and on cutting high-calorie, fatty food.
What types of bariatric surgery are there?
City Medical Centre performs four core types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Selection is individual and takes into account BMI, related conditions and the patient's goals.
Can I plan a pregnancy after surgery?
Pregnancy is an option after bariatric surgery, but doctors advise waiting at least 12–18 months. By then the body has stabilized, weight has reached target values and nutritional status has normalized.
Do I need to take vitamins after surgery?
Yes, after bariatric surgery vitamins cannot be skipped. As the digestive anatomy changes, some nutrients are absorbed less well, making regular vitamin and mineral supplements a permanent feature of the patient's life.
Can the weight come back?
Although weight regain after bariatric surgery is possible, it is very unlikely if you follow the doctor's advice. Proper eating, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are key.

Sleeve, bypass or SADI-S in Düsseldorf: a short guide
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 Düsseldorf, the choice between sleeve, classic bypass, mini bypass and SADI-S depends on BMI, related diseases and the result you want to reach.
The work-up is done in one building with its own lab, ultrasound and gastroscopy, so preparation is quick and without queues. After laparoscopic surgery, the patient stays under observation for 1 to 5 days depending on the extent of the operation. Within the first hours you may sit up, stand and drink. Most Düsseldorf patients are up and moving on day one.
What sets this programme apart is a result guarantee written into an official contract: weight loss is fixed legally, not just in words. Surgeons have 9–11 years in the field and work as a permanent team. Düsseldorf residents can tick the situations that sound familiar on the page and then check their case for free with a surgeon.
