When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
BMI is the key measure used to assess how severe obesity is. You get it by dividing body weight (kg) by height squared (m²). Surgery is generally justified at a BMI above 40, or above 35 when serious related conditions are present. Sometimes it is also considered at lower values — when non-surgical methods have not worked.
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
The operation involves removing most of the stomach and turning it into a narrow tube. As a result portions shrink a lot and the hunger hormone ghrelin falls, so the patient reaches fullness sooner and eats less.
Effectiveness: the method fits a BMI between 35 and 45. Average loss is 60–70% of excess weight.
Specifics: the effect is less durable than with bypass procedures. Ignoring the diet, especially high-calorie drinks and liquid meals, may bring the weight back.
Roux-en-Y gastric bypass
A small upper-stomach pouch of 50–70 ml is made and connected straight to the small intestine. It restricts how much food is eaten and reduces calorie uptake, as food follows a shorter path through the intestine.
Effectiveness: with a BMI over 45–50 and type 2 diabetes, this is the “gold standard”. Excess weight loss is as high as 75–85%.
Specifics: the result is more durable than with other bariatric techniques. Diabetes, hypertension and similar related conditions often enter remission. The changed digestive anatomy means lifelong vitamin and mineral supplements.
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: comparable to the classic Roux-en-Y bypass — patients lose up to 75–80% of excess weight.
Specifics: a shorter operation and quicker recovery. The procedure can technically be reversed, but the single anastomosis carries 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: among bariatric operations, one of the most powerful — 80–90% of excess weight goes, and it lasts long.
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.

City Medical Centre bariatric surgery centre
— your path
to confidence and harmony
City Medical Centre approaches obesity in a comprehensive way. Each patient, after the first examination, is assigned a personal diagnostic program (lab and instrumental) to identify all disorders in the body.
A method matched to your goal
Choosing the surgical method is individual for each patient at our clinic. Doctors first review your health, history of weight and related conditions and then propose the most suitable surgical option.
Support that stays in touch
City Medical Centre's team remains with you after surgery. Over the first year specialists watch your weight loss, monitor test results and respond to all questions regarding diet and recovery.
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
You don't have to go clinic to clinic. Our centre has everything needed for your work-up — own lab, ultrasound, gastroscopy. Fast preparation, no queues, one building.
Recovery after bariatric surgery
While recovery is largely individual, minimally invasive laparoscopic techniques keep rehab time as short as possible.
Duration
Observation at the clinic lasts 1 to 5 days, based on how extensive the surgery is and on related conditions.
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
Back to work in 7–14 days after surgery, depending on how physical your job happens to be.
Restrictions
The first weeks exclude bathhouse, sauna and intense physical exercise.
Diet
A step-by-step diet lasts 1–2 months, from liquids to solids, giving the stomach time to adapt.
Pace
On average, patients who follow the specialists' advice lose 10% of excess weight a month.
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! 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?
It is common to confuse them, but their goals are fundamentally different. Bariatric surgery treats obesity and related diseases medically. By changing how the digestive tract works, it addresses the causes of excess weight and metabolism. Plastic surgery shapes the body's outer contours; it does not treat obesity and has no effect on metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
We work with modern laparoscopic technique. The operation needs only 4 small punctures, 5 to 15 mm each. Cosmetic sutures are applied, so healed marks are 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?
Four main bariatric surgery types are available at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. The method is picked individually, considering BMI, related conditions and the patient's goals.
Can I plan a pregnancy after surgery?
Pregnancy is possible after bariatric surgery; doctors advise waiting no less than 12–18 months. This gives the body time to stabilize, for weight to reach target values and nutritional status to normalize.
Do I need to take vitamins after surgery?
Yes, bariatric surgery makes vitamins a must. Since digestive anatomy is changed, absorption of some nutrients drops, and regular vitamin and mineral supplements become permanent in the patient's life.
Can the weight come back?
Although weight regain after bariatric surgery is possible, it is very unlikely if you follow the doctor's advice. Proper eating, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are key.

Bariatric surgery in Poznan: what you should know
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 Poznan should know that it requires lifelong vitamin and mineral supplements.
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. Poznan residents get the same step-by-step guidance from the team.
If you are comparing bariatric surgery options in Poznan, look beyond the operation itself. Here the package bundles the work-up in the centre's own lab, laparoscopic surgery, the stay with meals and nursing, a doctor on hand 24/7 and a year of follow-up. Apply for a free surgeon consultation to see how this applies to your case.
