Surgery is prescribed only when clear criteria are met
To gauge obesity, doctors rely primarily on BMI, which equals body weight (kg) divided by the square of height (m²). An operation is usually warranted with a BMI over 40, or over 35 with serious associated conditions. Occasionally surgery is weighed at lower values as well, once non-surgical options have failed.
People often spend years on diets and physical activity, but the body counters: metabolism slows, appetite increases, lost weight creeps back. When it is plain that changing the diet and taking medication cannot fundamentally improve things alone, bariatric surgery is the only effective exit.

Sleeve gastrectomy
Most of the stomach is removed during surgery, and what remains becomes a narrow tube. This cuts portion size significantly and reduces ghrelin, the hormone of hunger, so patients feel full sooner and eat less.
Effectiveness: the method is appropriate for a BMI of 35 to 45. Average loss of excess weight is 60–70%.
Specifics: less durable results than bypass operations. Without sticking to the diet, especially avoiding high-calorie drinks and liquid food, the weight may 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: the operation is considered the “gold standard” for a BMI over 45–50 with type 2 diabetes. Excess weight loss reaches 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 is an improved version of the classic bypass. Unlike the standard method, the surgeon creates only one connection (anastomosis) between the small stomach and the small intestine. The simpler technique is easier on the patient and needs less recovery time.
Effectiveness: results comparable to classic Roux-en-Y bypass — up to 75–80% of excess weight lost.
Specifics: a faster operation and shorter recovery. The procedure can be undone technically, but there is a bile reflux risk from the single anastomosis.

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: ranks among the most powerful bariatric operations: up to 80–90% of excess weight lost, with lasting results.
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.

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 match the surgical method to each individual patient. They review your health, weight history and accompanying conditions before deciding, to offer you the most appropriate surgical treatment.

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
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
No running from clinic to clinic. Our centre has everything for your work-up, from its own lab to ultrasound and gastroscopy. Preparation is fast, queue-free and all under one roof.
Recovery is mostly down to the individual; still, minimally invasive laparoscopic methods keep rehabilitation as short as possible.

Duration
Observation at the clinic lasts 1 to 5 days, based on how extensive the surgery is and on related conditions.
Activity
Within hours of surgery, you can sit up, get on your feet and drink fluids.
Wound care
Absorbable sutures are used; they dissolve on their own.

Work
You can resume working 7–14 days after surgery, based on how physically demanding your job is.
Restrictions
The first weeks exclude bathhouse, sauna and intense physical exercise.
Diet
The prescribed staged diet runs 1–2 months, shifting from liquids to solids so the stomach adapts.

Pace
With the specialists' advice followed, average loss is 10% of excess weight per month.
Stabilization
The final result comes in 1.5–2 years. By that point the patient has developed stable eating habits that stop the weight from returning.
Important! Your recovery is overseen by City Medical Centre specialists, who offer psychological and medical support throughout each stage of weight loss.

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?
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?
The diet evolves in steps — from liquids to soft, then solid food — with a focus on protein and limits on high-calorie, fatty food.
What types of bariatric surgery are there?
City Medical Centre carries out four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. The choice of method is individual, based on BMI, related conditions and the patient's goals.
Can I plan a pregnancy after surgery?
Pregnancy after bariatric surgery can happen, though doctors advise holding off at least 12–18 months. In this period the body becomes stable, weight reaches target values and nutritional status normalizes.
Do I need to take vitamins after surgery?
Yes, bariatric surgery makes vitamins a must. Since digestive anatomy is changed, absorption of some nutrients drops, and regular vitamin and mineral supplements become permanent in the patient's life.
Can the weight come back?
Weight can come back after bariatric surgery, but this is very unlikely if you follow your doctor's advice. Proper nutrition, skipping high-calorie drinks and regular follow-up with City Medical Centre specialists are key.

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 Nuremberg 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.
Recovery is short thanks to the minimally invasive technique, and absorbable sutures dissolve on their own. Office work is usually resumed after 2–4 weeks and physical work after about 1.5 months; swimming is allowed after 30 days, with other exercise added gradually. For the first weeks, no sauna or intense training. Nuremberg residents get the same step-by-step guidance from the team.
Your investment covers more than surgery. The package includes the full diagnostic programme, the chosen laparoscopic method, inpatient care with food and nursing staff, round-the-clock medical presence and specialists tracking your weight and tests throughout the first year. For people searching for weight loss surgery in Nuremberg, the first consultation with the surgeon is free and takes about 15 minutes.
