Surgery is prescribed only when clear criteria are met
Obesity is graded mainly by BMI, calculated as body weight (kg) over height squared (m²). A BMI above 40 usually justifies surgery, as does a BMI above 35 with serious related conditions. In certain cases surgery is considered at lower values too, if approaches without surgery have not succeeded.
Years of various diets and workouts often end the same way: the body fights back, metabolism slows, appetite grows and the weight returns. If it becomes clear that medication and dietary changes alone cannot fundamentally improve the situation, bariatric surgery is the only effective way forward.

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 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
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: known as the “gold standard” for a BMI over 45–50 combined with type 2 diabetes. Excess weight loss hits 75–85%.
Specifics: the result lasts better than with other bariatric methods. Related conditions such as diabetes and hypertension often go into remission. Because the digestive anatomy changes, lifelong vitamin and mineral supplements are needed.

Mini gastric bypass (MGB)
An upgraded take on the classic bypass. In contrast to the standard method, only a single connection (anastomosis) is made between the small stomach and the small intestine. Being simpler, the technique is easier on the patient and shortens recovery.
Effectiveness: matches the classic Roux-en-Y bypass — patients' excess weight loss is up to 75–80%.
Specifics: brief surgery and rapid recovery. While technically reversible, the procedure has a bile reflux risk linked 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: a top-power bariatric operation — loss of excess weight reaches 80–90%, with a long-lasting result.
Specifics: appetite drops because the smaller stomach no longer has its ghrelin-producing zone, and bypassing part of the intestine cuts calorie absorption. It fits super obesity (BMI over 50), severe type 2 diabetes, or serves as a second stage following an ineffective sleeve.

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
Our doctors tailor the choice of surgical method to each patient. Ahead of the decision they study your health, weight history and related conditions to offer the best-suited surgical treatment.

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
Bariatric surgery at City Medical Centre is done laparoscopically, greatly shortening recovery. Most patients stand and walk on the first day and are back to normal life within a week.

Full diagnostics on site
No need to run between clinics. Our centre has everything for your work-up, from our own lab to ultrasound and gastroscopy. Preparation is quick, with no queues, all in one building.
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
Soon after surgery — within the first hours — you may sit up, stand and take 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
For the first few weeks, skip the bathhouse, sauna and intense exercise.
Diet
A staged diet is set for 1–2 months — from liquid to solid food — so the stomach can adapt.

Pace
Average monthly loss is 10% of excess weight for patients following the specialists' advice.
Stabilization
The final result takes 1.5–2 years. By that stage, the patient has stable eating habits in place that block weight regain.
Important! City Medical Centre specialists keep recovery under supervision and give psychological and medical support at every stage of losing weight.

Bariatric vs plastic surgery: what's the difference?
Many people confuse them, but the goals are fundamentally different. Bariatric surgery is a medical way to treat obesity and related diseases. It changes how the digestive tract works, getting at the causes of excess weight and metabolism. Plastic surgery only reshapes the body's outer contours; it 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 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?
At City Medical Centre there are four main types of bariatric surgery — sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Every method is chosen individually from 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 become essential after bariatric surgery. The changed digestive anatomy lowers absorption of some nutrients, so regular vitamin and mineral supplements turn into a permanent part of the patient's life.
Can the weight come back?
It is possible to regain weight after bariatric surgery, but very unlikely if you follow your doctor's advice. Proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists are essential.

The decision rests on clear criteria: body mass index, overall health with related chronic conditions, and failed previous attempts at weight loss. BMI is weight in kilograms divided by height in metres squared. Contraindications include acute illness, severe chronic or mental illness, and less than six months since breastfeeding ended. Mississauga patients receive a personal assessment against these points.
During the operation the surgeon works laparoscopically, which keeps rehabilitation as short as possible. Right after, you are under round-the-clock care in a ward, with meals and nursing included. After discharge, most people in Mississauga return to their normal routine within a week, following a diet plan and avoiding saunas and heavy exercise for the first weeks.
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 Mississauga to arrange the next steps.
