Surgery is prescribed only when clear criteria are met
BMI is the principal gauge of how advanced obesity is, found by dividing body weight (kg) by height squared (m²). Typically, a BMI above 40 — or above 35 with serious related conditions — justifies surgery. Some patients with lower values are considered for surgery too, if 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
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: suitable for a BMI of 35 to 45. Patients lose 60–70% of their excess weight on average.
Specifics: the result is not as long-lasting as with bypass surgery. Breaking the diet, particularly through high-calorie drinks and liquid food, can bring weight back.

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: known as the “gold standard” for a BMI over 45–50 combined with type 2 diabetes. Excess weight loss hits 75–85%.
Specifics: outcomes are more durable than with other bariatric procedures. Diabetes, hypertension and other related conditions often go into remission. With the digestive anatomy changed, lifelong vitamin and mineral supplements are a must.

Mini gastric bypass (MGB)
It is an improved variant of the classic bypass. Unlike the standard method, here the surgeon forms only one connection (anastomosis) linking the small stomach to the small intestine. The simpler technique is less demanding and needs less recovery time.
Effectiveness: similar to the classic Roux-en-Y bypass; up to 75–80% of excess weight is 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, a modern combined technique, pairs the benefits of sleeve gastrectomy and intestinal bypass. It is carried out in two stages: the stomach is reshaped into a narrow tube, after which the small intestine is rerouted so most of it is bypassed in active digestion.
Effectiveness: counted among the most powerful bariatric operations — 80–90% excess weight loss with a durable result.
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.

At City Medical Centre, obesity is approached as a whole. After the initial examination each patient is given an individual diagnostic program, both lab and instrumental, to find all disorders in the body.

A method matched to your goal
Our doctors pick the surgical method for every patient individually. They examine your health, weight history and related conditions before deciding, so they can propose the most suitable surgical treatment.

Support that stays in touch
City Medical Centre's team remains with you after surgery. Over the first year specialists watch your weight loss, monitor test results and respond to all questions regarding 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
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 is mostly down to the individual; still, minimally invasive laparoscopic methods keep rehabilitation as short as possible.

Duration
A clinic stay of 1 to 5 days under observation follows, depending on surgical extent and 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
A return to work is possible 7–14 days after surgery, based on how physical your job is.
Restrictions
In the first weeks, avoid the 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 end result is achieved in 1.5–2 years, when the patient already has stable eating habits that prevent weight regain.
Important! Specialists at City Medical Centre supervise recovery, providing medical and psychological support across every 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?
Modern laparoscopic technique allows the operation through 4 small punctures of 5 to 15 mm. Cosmetic sutures make the marks almost invisible when fully healed.
What diet do I need to follow?
Your diet changes in stages: from liquid food to soft, then to solid. The focus is on protein and on limiting high-calorie, fatty food.
What types of bariatric surgery are there?
City Medical Centre offers four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. The method is chosen individually according to BMI, related conditions and the patient's goals.
Can I plan a pregnancy after surgery?
Pregnancy after bariatric surgery is possible, but doctors advise waiting at least 12–18 months. During this time the body stabilizes, weight reaches target values and nutritional status normalizes.
Do I need to take vitamins after surgery?
Yes — vitamins are required after bariatric surgery. With the digestive anatomy changed, some nutrients are absorbed less well, and regular vitamin and mineral supplements become a permanent part of 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 Frankfurt am Main in these situations can discuss it at a consultation.
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 Frankfurt am Main patients are up and moving on day one.
If you are comparing bariatric surgery options in Frankfurt am Main, look beyond the operation itself. Here the package bundles the work-up in the centre's own lab, laparoscopic surgery, the stay with meals and nursing, a doctor on hand 24/7 and a year of follow-up.
