When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
BMI serves as the chief indicator of obesity severity. Divide body weight (kg) by height squared (m²) to calculate it. Surgery is normally justified at BMI above 40, or above 35 with serious accompanying conditions. In selected cases it is considered at lower values as well — if non-surgical methods did not help.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Past attempts to shed weight in conventional ways were unsuccessful
Why don't diets and exercise work for everyone?
For years many try diet after diet and exercise, but the body pushes back — metabolism slows down, appetite increases and lost kilos return. When it is evident that diet changes and medication alone cannot fundamentally change the situation, bariatric surgery remains the only effective way out.

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: recommended for a BMI of 35 to 45. Typically patients shed 60–70% of excess weight.
Specifics: results are less lasting than with bypass surgery. Weight can return if the diet is not kept, especially with high-calorie drinks and liquid foods.
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: the “gold standard” for patients with a BMI over 45–50 and type 2 diabetes. Up to 75–85% of excess weight is lost.
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)
The classic bypass, improved. Unlike the standard method, the surgeon forms just one connection (anastomosis) between the small stomach and the small intestine. A simpler technique puts less strain on the patient and cuts the time needed to recover.
Effectiveness: comparable to the classic Roux-en-Y bypass — patients lose up to 75–80% of excess weight.
Specifics: brief surgery and rapid recovery. While technically reversible, the procedure has a bile reflux risk linked to the single anastomosis.
Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S is a modern combined technique that unites the benefits of sleeve gastrectomy and intestinal bypass. It is done in two stages: first the stomach is turned into a narrow tube, then the small intestine is rerouted so that most 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: a smaller stomach reduces appetite by removing the ghrelin-producing zone, and rerouting food past part of the intestine limits calorie absorption. It suits 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
At City Medical Centre, bariatric operations are laparoscopic, which significantly shortens recovery. Most patients are up and active on day one and return to normal life within a week.
Full diagnostics on site
You won't need to visit several clinics. Our centre covers the whole work-up, from our in-house lab to ultrasound and gastroscopy. Quick preparation 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
Depending on the extent of surgery and related conditions, the patient is observed at the clinic for 1 to 5 days.
Activity
In the first hours post-op, sitting up, standing and drinking fluids are fine.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
7–14 days after surgery you can return to work, depending on how physical the job is.
Restrictions
The first weeks exclude bathhouse, sauna and intense physical exercise.
Diet
The stomach adapts through a staged diet over 1–2 months, progressing from liquids to solids.
Pace
On specialists' advice, patients typically lose an average of 10% of excess weight per month.
Stabilization
The final result is seen after 1.5–2 years. In that time the patient builds stable eating habits that keep the weight from returning.
Important! Specialists at City Medical Centre supervise recovery, providing medical and psychological support across every stage of weight loss.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
Many people confuse them, but the goals are fundamentally different. Bariatric surgery is a medical way to treat obesity and related diseases. It changes how the digestive tract works, getting at the causes of excess weight and metabolism. Plastic surgery only 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?
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?
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 provides four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. We choose each method individually by BMI, related conditions and the patient's goals.
Can I plan a pregnancy after surgery?
Getting pregnant after bariatric surgery is possible, but doctors advise waiting at least 12–18 months, so the body can stabilize, weight can reach target values and nutritional status can normalize.
Do I need to take vitamins after surgery?
Yes, vitamins after bariatric surgery are necessary. The body absorbs certain nutrients less well due to the changed digestive anatomy, so regular vitamin and mineral supplements become a permanent part of the patient's life.
Can the weight come back?
Regain after bariatric surgery is possible, but very unlikely if you follow the doctor's advice. Proper nutrition, no high-calorie drinks and regular follow-up visits with City Medical Centre specialists make the difference.

When bariatric surgery in Rotterdam makes sense
Mini gastric bypass is an improved version of the classic operation with a single connection between the small stomach and the intestine. The technique is simpler, recovery shorter, and weight loss reaches 75–80% of excess weight. It is technically reversible, but bile reflux is a possible risk. For people from Rotterdam, the surgeon explains such trade-offs before any decision.
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 Rotterdam patients are up and moving on day one.
Starting is simple. Leave your name and phone number or write in any messenger, and a coordinator will arrange a free consultation. In about 15 minutes the surgeon will say whether bariatric surgery is right for you and which method fits. For people from Rotterdam, this conversation is the fastest way to replace temporary fixes with a lasting solution.
