When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
Doctors assess obesity chiefly through BMI: take body weight (kg) and divide it by height squared (m²). Surgical treatment is usually justified at a BMI over 40, or over 35 with serious related conditions. Surgery may also be considered at lower values in some cases — where non-surgical approaches have failed.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Failure of previous attempts to lose weight by conventional means
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
Here the surgeon removes most of the stomach, reshaping it into a narrow tube. That greatly limits portion size and lowers ghrelin, the hunger hormone — the patient feels full much more quickly and eats less.
Effectiveness: the method suits a BMI of 35 to 45. On average patients lose 60–70% of their excess weight.
Specifics: durability is lower than with bypass operations. If the diet slips, especially with high-calorie drinks and liquid food, lost weight may come back.
Roux-en-Y gastric bypass
The operation creates a small 50–70 ml stomach pouch at the top and connects it directly with the small intestine. Less food can be taken in, and fewer calories are absorbed because the path through the gut is shorter.
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 effect lasts longer than with other bariatric methods. Related diseases, including diabetes and hypertension, often reach remission. As digestive anatomy changes, supplements of vitamins and minerals are needed for life.
Mini gastric bypass (MGB)
This is a refined form of the classic bypass. Unlike the standard technique, the surgeon makes just one connection (anastomosis) between the small stomach and the small intestine. The simpler approach is gentler on the patient and requires less recovery time.
Effectiveness: on par with the classic Roux-en-Y bypass — patients shed up to 75–80% of excess weight.
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 effective bariatric operations — 80–90% of excess weight is lost, and the result lasts long.
Specifics: appetite falls as the smaller stomach loses the zone that produces ghrelin, while food rerouted around part of the intestine yields fewer absorbed calories. Right 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 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
Our doctors select the surgical method for each patient individually. Before deciding, they assess your health, weight history and related conditions to suggest the most suitable 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
Bariatric surgery at City Medical Centre is done laparoscopically, greatly shortening recovery. Most patients stand and walk on the first day and are back to normal life within a week.
Full diagnostics on site
Skip the trips between clinics. Our centre provides everything for your work-up, our own lab through ultrasound and gastroscopy. Prep is quick and free of 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
Patients stay under observation at the clinic 1 to 5 days, depending on how extensive the surgery is 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
Returning to work takes 7–14 days after surgery, depending on how physical your work is.
Restrictions
Bathhouse, sauna and intense physical exercise are banned in early weeks.
Diet
You follow a staged diet for 1–2 months, going from liquid to solid food as the stomach adapts.
Pace
On specialists' advice, patients typically lose an average of 10% of excess weight per month.
Stabilization
The final result takes 1.5–2 years. By that stage, the patient has stable eating habits in place that block weight regain.
Important! Recovery is overseen by City Medical Centre specialists, with psychological and medical support at every step of weight loss.

Frequently asked questions
about bariatric surgery at CMC
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?
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?
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?
The four main types of bariatric surgery at City Medical Centre are sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each method is matched individually to BMI, related conditions and the patient's goals.
Can I plan a pregnancy after surgery?
Pregnancy after bariatric surgery is possible, though doctors recommend waiting at least 12–18 months. In that time the body stabilizes, weight reaches its target and nutritional status returns to normal.
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?
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 Hamburg
Bariatric surgery is a medical treatment for obesity and related diseases. Unlike plastic surgery, it changes how the digestive tract works and addresses the causes of excess weight. For patients from Hamburg, four main methods are available: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass and SADI-S. Each is chosen individually based on BMI, related conditions and personal goals.
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 Hamburg.
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. Hamburg residents can tick the situations that sound familiar on the page and then check their case for free with a surgeon.
