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
- Past attempts to shed weight in conventional ways were unsuccessful
Why don't diets and exercise work for everyone?
Many try all kinds of diets and exercise for years, yet the body defends itself — metabolism drops, hunger grows and lost weight returns. Once it is obvious that medication and a changed diet alone cannot fundamentally fix the situation, bariatric surgery becomes the only effective path.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
During the procedure the surgeon removes the greater part of the stomach, forming a narrow tube. Portions get far smaller and ghrelin, the hunger hormone, decreases, so the patient is satisfied faster and eats less.
Effectiveness: the method is used for a BMI of 35 to 45; average loss is 60–70% of excess weight.
Specifics: results are less lasting than with bypass surgery. Weight can return if the diet is not kept, especially with high-calorie drinks and liquid foods.
Roux-en-Y gastric bypass
The surgeon creates a small 50–70 ml pouch at the top of the stomach and connects it directly to the small intestine. This limits food intake and reduces calorie absorption by shortening the path food travels 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: 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 is an improved version of the classic bypass. Unlike the standard method, the surgeon creates only one connection (anastomosis) between the small stomach and the small intestine. The simpler technique is easier on the patient and needs less recovery time.
Effectiveness: like the classic Roux-en-Y bypass, it helps patients lose up to 75–80% of excess weight.
Specifics: shorter surgery and faster recovery. The procedure is technically reversible, but there is a risk of bile reflux due to the single anastomosis.
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: 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
Our doctors decide on the surgical method case by case. Before choosing, they evaluate your health, weight history and related conditions in order to offer the surgical treatment that fits best.
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
Bariatric operations at City Medical Centre use laparoscopy, which greatly cuts recovery time. Most patients move around on day one and get back to normal life within a week.
Full diagnostics on site
There is no need to rush between clinics. Our centre offers your entire work-up — our own lab, ultrasound, gastroscopy. Preparation goes quickly, with no queues, all in one building.
Recovery after bariatric surgery
The pace of recovery is largely personal, but minimally invasive laparoscopic techniques shorten rehabilitation as much as possible.
Duration
For 1 to 5 days the patient stays in the clinic under observation; this depends on the surgery's extent and related conditions.
Activity
In the early hours after surgery you can already sit up, stand and have fluids.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
You can resume working 7–14 days after surgery, based on how physically demanding your job is.
Restrictions
No sauna, no bathhouse and no intense physical exercise for the first weeks.
Diet
A staged diet is prescribed for 1–2 months — from liquids to solids to let the stomach adapt.
Pace
Patients who follow what specialists advise lose 10% of excess weight per month on average.
Stabilization
The final result is reached in 1.5–2 years. By then the patient has built stable eating habits that prevent the 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?
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?
Stage by stage, you move from liquid food to soft and then solid. Priority goes to protein, and high-calorie, fatty food is limited.
What types of bariatric surgery are there?
City Medical Centre provides four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. We choose each method individually by 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, 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?
Weight can come back after bariatric surgery, but this is very unlikely if you follow your doctor's advice. Proper nutrition, skipping high-calorie drinks and regular follow-up with City Medical Centre specialists are key.

Bariatric surgery in Sapporo: what you should know
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 Sapporo in these situations can discuss it at a consultation.
Several things are worth planning ahead. Pregnancy is advised no earlier than 12–18 months after surgery, once weight and nutritional status stabilise. Vitamins become a permanent part of life because the body absorbs some nutrients less well. Swimming waits 30 days, strength work longer. Patients from Sapporo discuss these points with the surgeon well before the operation date.
If you are comparing bariatric surgery options in Sapporo, 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.
