When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
Obesity is graded mainly by BMI, calculated as body weight (kg) over height squared (m²). A BMI above 40 usually justifies surgery, as does a BMI above 35 with serious related conditions. In certain cases surgery is considered at lower values too, if approaches without surgery have not succeeded.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Weight-loss attempts using conventional methods have not succeeded
Why don't diets and exercise work for everyone?
It is common to try various diets and exercise for years while the body resists — slower metabolism, stronger appetite, returning weight. When it becomes evident that diet changes and medication by themselves cannot fundamentally help, bariatric surgery becomes the only effective solution.

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 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
Using the top of the stomach, the surgeon creates a small 50–70 ml pouch joined directly to the small intestine. This limits intake and reduces the calories absorbed by cutting short the journey of food through 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: results last better than after other bariatric methods. Related conditions — diabetes, hypertension — often go into remission. The digestive anatomy is changed, so vitamin and mineral supplements are needed throughout 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: similar to the classic Roux-en-Y bypass; up to 75–80% of excess weight is lost.
Specifics: less time in surgery and a faster recovery. Technically the procedure is reversible, though the single anastomosis brings a risk of bile reflux.
Single anastomosis duodeno-ileal bypass (SADI-S)
A modern combined approach, SADI-S merges the benefits of sleeve gastrectomy with those of intestinal bypass. It takes two stages — turning the stomach into a narrow tube, then rerouting the small intestine so that the larger part is excluded from active digestion.
Effectiveness: one of the most powerful bariatric operations — excess weight loss reaches 80–90% with a long-lasting result.
Specifics: the reduced stomach lowers appetite once the ghrelin-producing zone is removed, and routing food past a section of intestine limits how many calories are absorbed. Suitable 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
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 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
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 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 after bariatric surgery
Much of recovery depends on the individual, but minimally invasive laparoscopic techniques keep the rehab stage as short as possible.
Duration
The patient stays under observation at the clinic for 1 to 5 days, depending on the extent of surgery and related conditions.
Activity
Soon after surgery — within the first hours — you may sit up, stand and take fluids.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
Back to work in 7–14 days after surgery, depending on how physical your job happens to be.
Restrictions
Bathhouse, sauna and intense workouts are off-limits for the first weeks.
Diet
A staged diet is set for 1–2 months — from liquid to solid food — so the stomach can adapt.
Pace
By following the specialists' advice, patients lose 10% of excess weight per month on average.
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! Specialists from City Medical Centre supervise recovery and provide psychological and medical support at each weight-loss stage.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
The two are often confused, yet their goals differ fundamentally. Bariatric surgery is a medical treatment for obesity and its related diseases. It alters how the digestive tract works, tackling the causes of excess weight and metabolism. Plastic surgery changes the body's outer contours; it neither treats obesity nor affects metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
Our approach is modern laparoscopic technique: 4 small punctures of 5 to 15 mm. We use cosmetic sutures, so the marks turn almost invisible after healing.
What diet do I need to follow?
Your meals progress in stages: liquid food, soft food, then solid. The stress is on protein and on reducing 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 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, taking vitamins after bariatric surgery is mandatory. Because digestion is anatomically altered, the body absorbs some nutrients poorly, so regular vitamin and mineral supplements stay in the patient's life permanently.
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 Hanover
Roux-en-Y gastric bypass creates a small 50–70 ml pouch at the top of the stomach and connects it straight to the small intestine. It is considered the gold standard for a BMI over 45–50 with type 2 diabetes, bringing excess weight loss of 75–85%. Anyone researching bypass in Hanover should know that it requires lifelong vitamin and mineral supplements.
During the operation the surgeon works laparoscopically, which keeps rehabilitation as short as possible. Right after, you are under round-the-clock care in a ward, with meals and nursing included. After discharge, most people in Hanover return to their normal routine within a week, following a diet plan and avoiding saunas and heavy exercise for the first weeks.
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. Hanover residents can tick the situations that sound familiar on the page and then check their case for free with a surgeon.
