When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
BMI is the primary tool for judging obesity. The formula: body weight (kg) divided by height squared (m²). Surgery is typically justified at a BMI above 40, or above 35 if there are serious related conditions. At times surgery is also considered with lower figures — provided non-surgical treatment has failed.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Standard approaches to weight loss have not worked before
Why don't diets and exercise work for everyone?
Many people try various diets and exercise for years, but the body fights back: metabolism slows, appetite grows and the lost weight returns. When it becomes clear that diet changes and medication alone cannot fundamentally improve the situation, bariatric surgery becomes the only effective way out.

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: fits patients with a BMI of 35 to 45. They lose 60–70% of 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
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: for a BMI over 45–50 with type 2 diabetes it is deemed the “gold standard”. Loss of excess weight is 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)
A modified version of the classic bypass. Unlike the standard operation, just one connection (anastomosis) joins the small stomach and the small intestine. The technique is simpler, so it is easier on the patient and recovery takes less time.
Effectiveness: results comparable to classic Roux-en-Y bypass — up to 75–80% of excess weight lost.
Specifics: surgery takes less time and recovery is faster. It can technically be reversed; the single anastomosis, though, poses a risk of bile reflux.
Single anastomosis duodeno-ileal bypass (SADI-S)
As a modern combined technique, SADI-S brings together the benefits of sleeve gastrectomy and intestinal bypass. Its two stages: making the stomach into a narrow tube, then rerouting the small intestine so the majority of it is excluded from active digestion.
Effectiveness: counted among the most powerful bariatric operations — 80–90% excess weight loss with a durable result.
Specifics: a smaller stomach curbs appetite because the ghrelin-producing zone is removed, and sending food past part of the intestine limits calorie absorption. It suits super obesity (BMI over 50), severe type 2 diabetes, or a second stage after a sleeve that did not work.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
Many confuse the two, yet their purposes are fundamentally different. Bariatric surgery is medicine's treatment for obesity and related diseases: it changes how the digestive tract operates and addresses the causes of excess weight and metabolism. Plastic surgery reshapes outer contours of the body without treating obesity or affecting metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
We apply modern laparoscopic technique, operating through 4 small punctures of 5 to 15 mm. Thanks to cosmetic sutures, the marks are almost invisible once they heal.
What diet do I need to follow?
You move through diet stages from liquid food to soft and finally solid. Protein comes first, and high-calorie, fatty food is restricted.
What types of bariatric surgery are there?
The four main types of bariatric surgery at City Medical Centre are sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each method is matched individually to 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 become essential after bariatric surgery. The changed digestive anatomy lowers absorption of some nutrients, so regular vitamin and mineral supplements turn into a permanent part of the patient's life.
Can the weight come back?
Weight may return after bariatric surgery, though that is very unlikely when you follow the doctor's advice. Key factors: proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists.

Bariatric surgery in Madrid: what you should know
Weight that began in childhood, a family history of obesity, shortness of breath on stairs, avoiding photos — these are common reasons people in Madrid 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.
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 Madrid return to their normal routine within a week, following a diet plan and avoiding saunas and heavy exercise for the first weeks.
Weight loss is written into the contract, and the package includes every stage: consultation, diagnostics, the operation, inpatient care with meals and a year of support. A personal coordinator guides you from day one. To begin, patients from Madrid leave a request on the page or message the clinic, then receive a free consultation with a bariatric surgeon.
