When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
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.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Unsuccessful past attempts at weight loss by traditional means
Why don't diets and exercise work for everyone?
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.

Bariatric surgery methods at City Medical Centre
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 intended for a BMI of 35 to 45. Excess weight goes down by 60–70% on average.
Specifics: the result holds up less well than after bypass operations. If the diet is broken, particularly with high-calorie drinks and liquid food, weight may come back.
Roux-en-Y gastric bypass
The surgeon shapes a small pouch, 50–70 ml, from the top of the stomach and routes it directly to the small intestine. Food intake drops and calorie absorption decreases as food covers a shorter distance in 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: longer-lasting than other bariatric methods. Conditions such as diabetes and hypertension often go into remission. Since the anatomy of digestion is altered, patients need vitamin and mineral supplements for life.
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: like the classic Roux-en-Y bypass, it helps patients lose up to 75–80% of excess weight.
Specifics: shorter surgery and faster recovery. The procedure is technically reversible, but there is a risk of bile reflux due to the single anastomosis.
Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S is a modern combination technique that draws on the benefits of both sleeve gastrectomy and intestinal bypass. In two stages, the stomach is first converted into a narrow tube and the small intestine is then rerouted to exclude its greater part from active digestion.
Effectiveness: a top-power bariatric operation — loss of excess weight reaches 80–90%, with a long-lasting result.
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.

— your path
to confidence and harmony
City Medical Centre sees obesity comprehensively. From the first examination, each patient has a personal diagnostic program (lab and instrumental) built to identify every disorder present in the body.
A method matched to your goal
Our doctors choose the surgical method individually for each patient. Before deciding, they review your health, weight history and related conditions to offer the most suitable surgical treatment.
Support that stays in touch
The City Medical Centre team keeps supporting you after the operation. All through the first year, specialists track how your weight drops, check your tests and handle every question on diet and recovery.
Fast recovery
City Medical Centre performs bariatric operations laparoscopically, which shortens recovery considerably. Most patients are on their feet on day one and back to normal life within a week.
Full diagnostics on site
No need to run between clinics. Our centre has everything for your work-up, from our own lab to ultrasound and gastroscopy. Preparation is quick, with no queues, all in one building.
Recovery after bariatric surgery
The pace of recovery is largely personal, but minimally invasive laparoscopic techniques shorten rehabilitation as much as possible.
Duration
Patients stay under observation at the clinic 1 to 5 days, depending on how extensive the surgery is 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
Returning to work takes 7–14 days after surgery, depending on how physical your work is.
Restrictions
For the first few weeks, skip the bathhouse, sauna and intense exercise.
Diet
The prescribed staged diet runs 1–2 months, shifting from liquids to solids so the stomach adapts.
Pace
Patients who follow what specialists advise lose 10% of excess weight per month on average.
Stabilization
Reaching the final result takes 1.5–2 years. The patient has by then built steady eating habits that prevent 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?
People often confuse these two, though their aims are fundamentally different. Bariatric surgery is medical treatment of obesity and associated diseases. It changes the way the digestive tract works, acting on the causes of excess weight and on metabolism. Plastic surgery alters outer body contours and does not treat obesity or affect 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?
Diet changes happen in stages, from liquids to soft food and then solids. It centers on protein and limits high-calorie, fatty food.
What types of bariatric surgery are there?
There are four main types of bariatric surgery at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. BMI, related conditions and the patient's goals guide the individual choice of method.
Can I plan a pregnancy after surgery?
It is possible to get pregnant after bariatric surgery, but doctors recommend a minimum wait of 12–18 months. During it the body stabilizes, weight reaches its target and nutritional status is normalized.
Do I need to take vitamins after surgery?
Yes, after bariatric surgery vitamins cannot be skipped. As the digestive anatomy changes, some nutrients are absorbed less well, making regular vitamin and mineral supplements a permanent feature of the patient's life.
Can the weight come back?
It is possible to regain weight after bariatric surgery, but very unlikely if you follow your doctor's advice. Proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are essential.

Weight loss surgery in Amsterdam step by step
Weight that began in childhood, a family history of obesity, shortness of breath on stairs, avoiding photos — these are common reasons people in Amsterdam start thinking about surgery. A consultation is warranted not only by a high BMI but also by related conditions. The surgeon reviews your health and weight history and offers the most suitable of the four surgical methods.
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. Amsterdam residents get the same step-by-step guidance from the team.
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. Amsterdam residents can tick the situations that sound familiar on the page and then check their case for free with a surgeon.
