When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
The main way to assess the degree of obesity is BMI. It is body weight (kg) divided by height squared (m²). Generally, surgery is justified with BMI above 40, or above 35 combined with serious related conditions. Lower values may sometimes be considered for surgery too, when non-surgical measures have failed.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Previous efforts at weight loss through standard methods did not work
Why don't diets and exercise work for everyone?
Many spend years on diets and exercise, and the body fights them all the way: metabolism slows, appetite grows, the lost kilos come back. As soon as it is clear that medication and diet changes alone cannot fundamentally improve the situation, bariatric surgery is the only effective way out.

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: this method is for a BMI of 35 to 45. Patients drop 60–70% of excess weight on average.
Specifics: durability is lower than with bypass operations. If the diet slips, especially with high-calorie drinks and liquid food, lost weight may come back.
Roux-en-Y gastric bypass
The surgeon forms a small 50–70 ml pouch at the top of the stomach and joins it straight to the small intestine. This restricts food intake and cuts calorie absorption by shortening the route food takes 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: the result endures better than with alternative bariatric methods. Associated diabetes and hypertension frequently go into remission. Lifelong vitamin and mineral supplements are required because the digestive anatomy changes.
Mini gastric bypass (MGB)
This is an enhanced form of the classic bypass. The standard method differs: here the surgeon makes only one connection (anastomosis) between the small stomach and the small intestine. Thanks to the simpler technique, the patient has an easier time and recovers faster.
Effectiveness: comparable with the classic Roux-en-Y bypass: patients drop up to 75–80% of excess weight.
Specifics: a faster operation and shorter recovery. The procedure can be undone technically, but there is a bile reflux risk from the single anastomosis.
Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S is a modern combined technique that unites the benefits of sleeve gastrectomy and intestinal bypass. It is done in two stages: first the stomach is turned into a narrow tube, then the small intestine is rerouted so that most of it is excluded from active digestion.
Effectiveness: a top-power bariatric operation — loss of excess weight reaches 80–90%, with a long-lasting result.
Specifics: a reduced stomach without its ghrelin-producing zone means less appetite, and diverting food past part of the intestine restricts calorie absorption. It is suited to super obesity (BMI over 50), severe type 2 diabetes, or a second stage after an ineffective sleeve.

City Medical Centre bariatric surgery centre
— your path
to confidence and harmony
At City Medical Centre, obesity is approached as a whole. After the initial examination each patient is given an individual diagnostic program, both lab and instrumental, to find all disorders in the body.
A method matched to your goal
Our doctors choose the surgical method individually for each patient. Before deciding, they review your health, weight history and related conditions to offer the most suitable surgical treatment.
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
At City Medical Centre bariatric surgery is laparoscopic, making recovery much shorter. Most patients are up and walking on the first day and resume normal 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
Each patient recovers differently, but minimally invasive laparoscopic techniques keep rehabilitation as brief 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
Sitting up, standing and drinking are allowed in the first hours after surgery.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
Work can be resumed 7–14 days after surgery, depending on how physically demanding it is.
Restrictions
For the first few weeks, skip the bathhouse, sauna and intense exercise.
Diet
A staged diet is prescribed for 1–2 months — from liquids to solids to let the stomach adapt.
Pace
On specialists' advice, patients typically lose an average of 10% of excess weight per 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! Your recovery is overseen by City Medical Centre specialists, who offer psychological and medical support throughout each stage of weight loss.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
People often confuse these two, though their aims are fundamentally different. Bariatric surgery is medical treatment of obesity and associated diseases. It changes the way the digestive tract works, acting on the causes of excess weight and on metabolism. Plastic surgery alters outer body contours and does not treat obesity or affect metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
We use modern laparoscopic technique. The operation is done through 4 small punctures of 5 to 15 mm. Cosmetic sutures are placed, so once healed the marks become almost invisible.
What diet do I need to follow?
The diet shifts in stages — liquid, then soft, then solid food. Protein is the priority, while high-calorie, fatty food is limited.
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 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, 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?
Weight can be regained after bariatric surgery, but this is very unlikely with the doctor's advice followed. Proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are crucial.

Sleeve, bypass or SADI-S in Copenhagen: a short guide
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 Copenhagen 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. Copenhagen residents get the same step-by-step guidance from the team.
Your investment covers more than surgery. The package includes the full diagnostic programme, the chosen laparoscopic method, inpatient care with food and nursing staff, round-the-clock medical presence and specialists tracking your weight and tests throughout the first year. For people searching for weight loss surgery in Copenhagen, the first consultation with the surgeon is free and takes about 15 minutes.
