Surgery is prescribed only when clear criteria are met
BMI is the primary tool for judging obesity. The formula: body weight (kg) divided by height squared (m²). Surgery is typically justified at a BMI above 40, or above 35 if there are serious related conditions. At times surgery is also considered with lower figures — provided non-surgical treatment has failed.
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.

Sleeve gastrectomy
The surgeon takes out most of the stomach and shapes the rest into a narrow tube. Portion size shrinks sharply and ghrelin, the hunger hormone, drops, so fullness comes much faster and the patient eats less.
Effectiveness: the method is used for a BMI of 35 to 45; average loss is 60–70% of excess weight.
Specifics: compared with bypass operations, the result is less stable. When the diet is not followed — notably with high-calorie drinks and liquid food — weight may return.

Roux-en-Y gastric bypass
At the top of the stomach the surgeon makes a small 50–70 ml pouch, linking it directly to the small intestine. Intake of food is restricted and calorie absorption falls, since food passes through less of the gut.
Effectiveness: this operation is seen as the “gold standard” with a BMI above 45–50 and type 2 diabetes. Excess weight falls by up to 75–85%.
Specifics: results hold better than with other bariatric methods. Related conditions like diabetes and hypertension frequently go into remission. Since digestive anatomy is altered, vitamin and mineral supplements are needed for life.

Mini gastric bypass (MGB)
This procedure improves on the classic bypass. Instead of the standard approach, the surgeon creates a single connection (anastomosis) between the small stomach and the small intestine. A simpler technique means an easier experience for the patient and a shorter recovery.
Effectiveness: equal to the classic Roux-en-Y bypass — up to 75–80% of excess weight is shed.
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: a top-power bariatric operation — loss of excess weight 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 approaches obesity in a comprehensive way. Each patient, after the first examination, is assigned a personal diagnostic program (lab and instrumental) to identify all disorders in the body.

A method matched to your goal
Each patient gets an individually chosen surgical method from our doctors. Before a decision, they look at your health, weight history and associated conditions to recommend the most fitting surgical treatment.

Support that stays in touch
Once the operation is done, the City Medical Centre team stays alongside you. Throughout the first year specialists follow your weight loss, review tests and answer all questions on diet and recovery.

Fast recovery
Bariatric operations at City Medical Centre use laparoscopy, which greatly cuts recovery time. Most patients move around on day one and get back to normal life within a week.

Full diagnostics on site
There is no need to rush between clinics. Our centre offers your entire work-up — our own lab, ultrasound, gastroscopy. Preparation goes quickly, with no queues, all in one building.
Recovery largely depends on the individual, but minimally invasive laparoscopic techniques keep rehabilitation as short as possible.

Duration
The patient is monitored at the clinic for 1 to 5 days, according to the extent of surgery and any related conditions.
Activity
Already in the first hours post-surgery you are allowed to sit up, stand and drink.
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
For the first few weeks, skip the bathhouse, sauna and intense exercise.
Diet
A staged diet is set for 1–2 months — from liquid to solid food — so the stomach can adapt.

Pace
On average, patients who follow the specialists' advice lose 10% of excess weight a month.
Stabilization
In 1.5–2 years the final result is reached, and by then the patient's stable eating habits prevent the weight coming back.
Important! Recovery takes place under the supervision of City Medical Centre specialists, who give psychological and medical support at all weight-loss stages.

Bariatric vs plastic surgery: what's the difference?
Many mix them up, but they pursue fundamentally different goals. Bariatric surgery medically treats obesity and related diseases by changing how the digestive tract functions, addressing the causes of excess weight and metabolism. Plastic surgery reshapes the external contours of the body; it does not treat obesity or influence 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?
In stages, your diet goes from liquid to soft to solid food. The main focus is protein and restricting high-calorie, fatty food.
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?
After bariatric surgery pregnancy is possible, yet doctors recommend at least 12–18 months of waiting. Meanwhile the body stabilizes, weight arrives at target values and nutritional 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.

SADI-S combines a sleeve with intestinal bypass in two stages and is one of the most powerful bariatric operations, with 80–90% excess weight loss and a long-lasting result. It suits super obesity with a BMI over 50, severe type 2 diabetes, or a second stage after an ineffective sleeve. Anyone in Stuttgart in these situations can discuss it at a consultation.
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 Stuttgart.
A permanent team — not a duty shift — handles your case, and the whole package is transparent. Included are the operation, 24/7 care in the ward, meals, nursing and a personal coordinator from day one, plus support throughout the first year. Stuttgart patients also get a contractual result guarantee. Book a free consultation to discuss your situation.
