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
- No success with earlier tries to slim down by usual means
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
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: works for a BMI from 35 to 45. On average, 60–70% of the excess weight is lost.
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
A small upper-stomach pouch of 50–70 ml is made and connected straight to the small intestine. It restricts how much food is eaten and reduces calorie uptake, as food follows a shorter path through the intestine.
Effectiveness: regarded as the “gold standard” for a BMI over 45–50 with type 2 diabetes. Loss of excess weight reaches 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)
This operation is an improvement on the classic bypass. Compared with the standard technique, the surgeon creates a single connection (anastomosis) between the small stomach and the small intestine. Its simplicity makes it easier for the patient, with less recovery time.
Effectiveness: close to the classic Roux-en-Y bypass, with patients losing up to 75–80% of excess weight.
Specifics: quicker surgery and a speedier recovery. The procedure is technically reversible; however, the single anastomosis creates a bile reflux risk.
Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S is a modern combination technique that draws on the benefits of both sleeve gastrectomy and intestinal bypass. In two stages, the stomach is first converted into a narrow tube and the small intestine is then rerouted to exclude its greater part from active digestion.
Effectiveness: one of the most powerful options in bariatric surgery: excess weight loss of 80–90%, lasting a long time.
Specifics: the smaller stomach, minus its ghrelin-producing zone, dampens appetite, and bypassing a portion of the intestine limits calorie absorption. It is an option in super obesity (BMI over 50), severe type 2 diabetes, or as a second stage after an ineffective sleeve.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
The two are often mistaken for each other, but their goals are fundamentally different. Bariatric surgery provides medical treatment for obesity and related diseases. Changing how the digestive tract works, it deals with the causes of excess weight and metabolism. Plastic surgery modifies 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?
The operation uses modern laparoscopic technique, through 4 small punctures of 5 to 15 mm. We place cosmetic sutures, and after healing the marks become almost invisible.
What diet do I need to follow?
In stages, your diet goes from liquid to soft to solid food. The main focus is protein and restricting high-calorie, fatty food.
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 after bariatric surgery is possible, though doctors recommend waiting at least 12–18 months. In that time the body stabilizes, weight reaches its target and nutritional status returns to normal.
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 may return after bariatric surgery, though that is very unlikely when you follow the doctor's advice. Key factors: proper nutrition, avoiding high-calorie drinks and regular follow-up with City Medical Centre specialists.

When bariatric surgery in Chicago makes sense
Mini gastric bypass is an improved version of the classic operation with a single connection between the small stomach and the intestine. The technique is simpler, recovery shorter, and weight loss reaches 75–80% of excess weight. It is technically reversible, but bile reflux is a possible risk. For people from Chicago, the surgeon explains such trade-offs before any decision.
The work-up is done in one building with its own lab, ultrasound and gastroscopy, so preparation is quick and without queues. After laparoscopic surgery, the patient stays under observation for 1 to 5 days depending on the extent of the operation. Within the first hours you may sit up, stand and drink. Most Chicago patients are up and moving on day one.
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 Chicago, the first consultation with the surgeon is free and takes about 15 minutes.
