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
- Unsuccessful past attempts at weight loss by traditional means
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 takes out most of the stomach and shapes the rest into a narrow tube. Portion size shrinks sharply and ghrelin, the hunger hormone, drops, so fullness comes much faster and the patient eats less.
Effectiveness: the method fits a BMI between 35 and 45. Average loss is 60–70% of excess weight.
Specifics: compared with bypass operations, the result is less stable. When the diet is not followed — notably with high-calorie drinks and liquid food — 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: regarded as the “gold standard” for a BMI over 45–50 with type 2 diabetes. Loss of excess weight reaches 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 operation is an improvement on the classic bypass. Compared with the standard technique, the surgeon creates a single connection (anastomosis) between the small stomach and the small intestine. Its simplicity makes it easier for the patient, with less recovery time.
Effectiveness: like the classic Roux-en-Y bypass, it helps patients lose up to 75–80% of excess weight.
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)
SADI-S is a contemporary combined technique uniting what is best in sleeve gastrectomy and intestinal bypass. Two stages are involved: first a narrow tube is formed from the stomach, then the small intestine is rerouted, leaving most of it outside active digestion.
Effectiveness: ranks among the most powerful bariatric operations: up to 80–90% of excess weight lost, with lasting results.
Specifics: removal of the ghrelin-producing zone shrinks the stomach and appetite, and routing food past part of the intestine curbs calorie absorption. Appropriate for super obesity (BMI over 50), severe type 2 diabetes, or as a second stage after a sleeve that failed.

City Medical Centre bariatric surgery centre
— your path
to confidence and harmony
City Medical Centre takes a comprehensive approach to obesity. After the first examination, each patient gets a personal diagnostic program (lab and instrumental) to identify every disorder 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
The City Medical Centre team is with you after surgery too. For the full first year, specialists track weight loss, keep an eye on your tests and answer every diet and recovery question.
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
Forget going between clinics. Everything for your work-up is here, including our own lab, ultrasound and gastroscopy. Preparation is quick and queue-free, all in a single building.
Recovery after bariatric surgery
Recovery is very much individual, though minimally invasive laparoscopic techniques keep the rehabilitation phase as short as possible.
Duration
The patient is kept under clinic observation for 1 to 5 days, depending on the scale of surgery and related conditions.
Activity
Already in the first hours post-surgery you are allowed to sit up, stand and drink.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
Depending on the physical demands of your job, you can return to work 7–14 days after surgery.
Restrictions
Bathhouse, sauna and intense physical exercise are banned in early weeks.
Diet
A step-by-step diet lasts 1–2 months, from liquids to solids, giving the stomach time to adapt.
Pace
With the specialists' advice followed, average loss is 10% of excess weight per month.
Stabilization
The final outcome arrives within 1.5–2 years. By this time the patient has lasting eating habits that stop the weight returning.
Important! Recovery is overseen by City Medical Centre specialists, with psychological and medical support at every step of weight loss.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
The two are often mistaken for each other, but their goals are fundamentally different. Bariatric surgery provides medical treatment for obesity and related diseases. Changing how the digestive tract works, it deals with the causes of excess weight and metabolism. Plastic surgery modifies 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?
The operation uses modern laparoscopic technique, through 4 small punctures of 5 to 15 mm. We place cosmetic sutures, and after healing the marks become almost invisible.
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?
City Medical Centre performs four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each method is chosen individually based on 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, vitamins are essential after bariatric surgery. As digestive anatomy changes, the body absorbs certain nutrients less well, so regular vitamin and mineral supplements become a lasting part of the patient's life.
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.

Sleeve, bypass or SADI-S in Zaragoza: a short guide
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 Zaragoza in these situations can discuss it at a consultation.
It begins with a surgeon's consultation: medical history, choice of method and a recovery plan. Patients from Zaragoza then complete a work-up — blood and urine tests, biochemistry, HbA1c, coagulation, chest X-ray, ECG, abdominal and kidney ultrasound, leg vein Doppler and a required gastroscopy — plus consultations with a GP, endocrinologist, psychiatrist, cardiologist and, for women, a gynecologist.
Everything needed for the result is combined in one package, with no hidden fees and no surprises. For patients from Zaragoza, it includes surgery by a dedicated team, round-the-clock care in the ward with meals and nursing, a doctor nearby 24/7 and a personal coordinator. The first step is a free 15-minute consultation with a bariatric surgeon.
