When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
BMI serves as the chief indicator of obesity severity. Divide body weight (kg) by height squared (m²) to calculate it. Surgery is normally justified at BMI above 40, or above 35 with serious accompanying conditions. In selected cases it is considered at lower values as well — if non-surgical methods did not help.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Earlier attempts to lose weight by conventional means have failed
Why don't diets and exercise work for everyone?
Many people keep trying diets and exercise for years while the body resists: metabolism slows, appetite climbs and the weight they lost comes back. When diet changes and medicines alone clearly cannot fundamentally improve the situation, bariatric surgery turns into the only effective way out.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
In surgery, most of the stomach is taken out and the rest is formed into a narrow tube. Portions become far smaller and ghrelin, the hormone behind hunger, drops, so the patient feels full quicker and eats less.
Effectiveness: this method is for a BMI of 35 to 45. Patients drop 60–70% of excess weight on average.
Specifics: the result is less durable than with bypass operations. If the diet is not followed, especially with high-calorie drinks and liquid food, the weight can return.
Roux-en-Y gastric bypass
A 50–70 ml pouch is formed at the upper end of the stomach and linked directly to the small intestine. It limits food intake and lowers calorie absorption because food moves along a shorter stretch of the gut.
Effectiveness: this operation is seen as the “gold standard” with a BMI above 45–50 and type 2 diabetes. Excess weight falls by up to 75–85%.
Specifics: results hold better than with other bariatric methods. Related conditions like diabetes and hypertension frequently go into remission. Since digestive anatomy is altered, vitamin and mineral supplements are needed 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: on par with the classic Roux-en-Y bypass — patients shed up to 75–80% of excess weight.
Specifics: the operation is shorter and recovery faster. Reversal is technically possible, but a single anastomosis means a risk of bile reflux.
Single anastomosis duodeno-ileal bypass (SADI-S)
A modern combined approach, SADI-S merges the benefits of sleeve gastrectomy with those of intestinal bypass. It takes two stages — turning the stomach into a narrow tube, then rerouting the small intestine so that the larger part is excluded from active digestion.
Effectiveness: among bariatric operations, one of the most powerful — 80–90% of excess weight goes, and it lasts long.
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
The City Medical Centre team remains by your side after surgery. For the whole first year, specialists follow your weight loss, check your tests and answer every question about 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
Running around different clinics is not necessary. Our centre has all you need for your work-up, from our lab to ultrasound and gastroscopy. Preparation is fast and queue-free, in one building.
Recovery after bariatric surgery
Recovery depends heavily on the individual, but minimally invasive laparoscopic methods keep rehabilitation as short as possible.
Duration
The length of clinic observation is 1 to 5 days, depending on the extent of the operation and related conditions.
Activity
In the first hours after the operation you can sit up, stand and drink fluids.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
A return to work is possible 7–14 days after surgery, based on how physical your job is.
Restrictions
In the early weeks, intense exercise, sauna and bathhouse are ruled out.
Diet
A step-by-step diet lasts 1–2 months, from liquids to solids, giving the stomach time to adapt.
Pace
Following the specialists' advice, patients lose on average 10% of excess weight per month.
Stabilization
The final result is seen after 1.5–2 years. In that time the patient builds stable eating habits that keep the weight from returning.
Important! City Medical Centre specialists keep recovery under supervision and give psychological and medical support at every stage of losing weight.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
The two are often confused, yet their goals differ fundamentally. Bariatric surgery is a medical treatment for obesity and its related diseases. It alters how the digestive tract works, tackling the causes of excess weight and metabolism. Plastic surgery changes the body's outer contours; it neither treats obesity nor affects 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?
Your meals progress in stages: liquid food, soft food, then solid. The stress is on protein and on reducing high-calorie, fatty food.
What types of bariatric surgery are there?
City Medical Centre performs four core types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Selection is individual and takes into account BMI, related conditions and the patient's goals.
Can I plan a pregnancy after surgery?
Pregnancy after bariatric surgery is possible, but doctors advise waiting at least 12–18 months. During this time the body stabilizes, weight reaches target values and nutritional status normalizes.
Do I need to take vitamins after surgery?
Yes, taking vitamins after bariatric surgery is mandatory. Because digestion is anatomically altered, the body absorbs some nutrients poorly, so regular vitamin and mineral supplements stay in the patient's life permanently.
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.

Weight loss surgery in Gothenburg step by step
Sleeve gastrectomy turns most of the stomach into a narrow tube, reducing portion size and levels of ghrelin, the hunger hormone. It suits a BMI of 35 to 45, with patients losing on average 60–70% of excess weight. For anyone from Gothenburg with a higher BMI or type 2 diabetes, a bypass may fit better; the surgeon compares options at the consultation.
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 Gothenburg build stable eating habits that keep the weight from returning.
Before spending on another diet, get a professional assessment. A short no-cost talk with the surgeon, about a quarter of an hour, shows whether your BMI and related conditions justify surgery. If they do, one package takes you through tests, the operation, care in the ward and follow-up, with the weight loss result set in a contract. Residents of Gothenburg can apply online.
