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
- Weight-loss attempts using conventional methods have not succeeded
Why don't diets and exercise work for everyone?
Plenty of people diet and exercise for years, only for the body to resist: a slower metabolism, a bigger appetite and the weight coming back. When diet changes and medication clearly cannot fundamentally improve matters on their own, the only effective option left is bariatric surgery.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
During surgery the surgeon removes most of the stomach, turning it into a narrow tube. This greatly reduces portion size and lowers ghrelin, the hunger hormone, so the patient feels full much faster and eats less.
Effectiveness: suitable for a BMI of 35 to 45. Patients lose 60–70% of their excess weight on average.
Specifics: bypass operations give a more durable result. Should the diet be ignored, especially with high-calorie drinks and liquid food, weight can 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: the operation counts as the “gold standard” for BMI above 45–50 with type 2 diabetes; 75–85% of excess weight is lost.
Specifics: outcomes are more durable than with other bariatric procedures. Diabetes, hypertension and other related conditions often go into remission. With the digestive anatomy changed, lifelong vitamin and mineral supplements are a must.
Mini gastric bypass (MGB)
This is a refined form of the classic bypass. Unlike the standard technique, the surgeon makes just one connection (anastomosis) between the small stomach and the small intestine. The simpler approach is gentler on the patient and requires less recovery time.
Effectiveness: matches the classic Roux-en-Y bypass — patients' excess weight loss is up to 75–80%.
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 an up-to-date combined technique joining the strengths of sleeve gastrectomy and intestinal bypass. There are two stages: the stomach is first made into a narrow tube, and then the small intestine is rerouted to exclude most of it from active digestion.
Effectiveness: ranks among the most powerful bariatric operations: up to 80–90% of excess weight lost, with lasting results.
Specifics: with the ghrelin-producing zone removed, the smaller stomach reduces appetite; redirecting food past part of the intestine limits calorie uptake. Used for super obesity (BMI over 50), severe type 2 diabetes, or as a second stage when a sleeve was ineffective.

City Medical Centre bariatric surgery centre
— your path
to confidence and harmony
The approach to obesity at City Medical Centre is comprehensive. Following an initial examination, a personal diagnostic program — lab and instrumental — is drawn up for each patient to detect every disorder in the body.
A method matched to your goal
The surgical method is selected individually by our doctors for every patient. Your health, weight history and related conditions are reviewed first, so the most suitable surgical treatment can be offered.
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
Laparoscopic bariatric operations at City Medical Centre make recovery far shorter. Most patients are moving on day one and resume their 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
Recovery is very much individual, though minimally invasive laparoscopic techniques keep the rehabilitation phase as short as possible.
Duration
The patient stays under observation at the clinic for 1 to 5 days, depending on the extent of surgery and related conditions.
Activity
Within hours of surgery, you can sit up, get on your feet and drink fluids.
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
No bathhouse, sauna or intense physical exercise during the first weeks.
Diet
Doctors prescribe a staged diet for 1–2 months, from liquids through to solids, for the stomach 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 supervised by City Medical Centre specialists, who provide psychological and medical support at every stage 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?
Modern laparoscopic technique is what we use. Just 4 small punctures of 5 to 15 mm are needed for the operation. Cosmetic sutures mean the marks are nearly invisible after healing.
What diet do I need to follow?
The diet evolves in steps — from liquids to soft, then solid food — with a focus on protein and limits on high-calorie, fatty food.
What types of bariatric surgery are there?
Four main types of bariatric surgery are performed at City Medical Centre: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each is selected individually based on BMI, related conditions and patient 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 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?
Regaining weight after bariatric surgery is possible, yet very unlikely when you stick to the doctor's advice. The keys are proper nutrition, no high-calorie drinks and regular check-ups with City Medical Centre specialists.

Bariatric surgery in Krakow: from consultation to result
Surgery is usually justified with a BMI above 40, or above 35 when serious related conditions are present, and sometimes at lower values if other approaches have failed. People in Krakow who have carried 30 kg or more above normal for years, whose weight returns after every diet, or who live with type 2 diabetes, hypertension or joint pain are typical candidates.
Eating changes in stages. A staged diet lasts 1–2 months, moving from liquid to soft to solid food so the stomach can adapt, with the focus on protein and limited high-calorie, fatty dishes. Following specialist advice, patients lose on average 10% of excess weight per month. Those from Krakow build stable eating habits that keep the weight from returning.
There are no hidden fees: one package covers everything required for the result. It brings together experienced surgeons, round-the-clock care, meals, nursing, a coordinator and a legal result guarantee. Tick the situations that apply to you and request a free check of your case; a coordinator will contact patients from Krakow to arrange the next steps.
