When is bariatric surgery justified?
Surgery is prescribed only when clear criteria are met
The role of body mass index (BMI)
To gauge obesity, doctors rely primarily on BMI, which equals body weight (kg) divided by the square of height (m²). An operation is usually warranted with a BMI over 40, or over 35 with serious associated conditions. Occasionally surgery is weighed at lower values as well, once non-surgical options have failed.
Key factors
- The patient's body mass index (BMI)
- Overall health and any related chronic conditions
- Weight-loss attempts using conventional methods have not succeeded
Why don't diets and exercise work for everyone?
It is common to try various diets and exercise for years while the body resists — slower metabolism, stronger appetite, returning weight. When it becomes evident that diet changes and medication by themselves cannot fundamentally help, bariatric surgery becomes the only effective solution.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
Most of the stomach is removed during surgery, and what remains becomes a narrow tube. This cuts portion size significantly and reduces ghrelin, the hormone of hunger, so patients feel full sooner and eat less.
Effectiveness: recommended for a BMI of 35 to 45. Typically patients shed 60–70% of excess weight.
Specifics: the result holds up less well than after bypass operations. If the diet is broken, particularly with high-calorie drinks and liquid food, 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: viewed as the “gold standard” for BMI over 45–50 plus type 2 diabetes. It removes 75–85% of excess weight.
Specifics: the result is more durable than with other bariatric techniques. Diabetes, hypertension and similar related conditions often enter remission. The changed digestive anatomy means lifelong vitamin and mineral supplements.
Mini gastric bypass (MGB)
It is an improved variant of the classic bypass. Unlike the standard method, here the surgeon forms only one connection (anastomosis) linking the small stomach to the small intestine. The simpler technique is less demanding 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: 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)
SADI-S is a contemporary combined technique uniting what is best in sleeve gastrectomy and intestinal bypass. Two stages are involved: first a narrow tube is formed from the stomach, then the small intestine is rerouted, leaving most of it outside active digestion.
Effectiveness: counted among the most powerful bariatric operations — 80–90% excess weight loss with a durable result.
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
You are not left alone after surgery — the City Medical Centre team stays with you. Across the first year, specialists follow your weight loss, monitor tests and answer all diet and recovery questions.
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 shuttling between clinics. Your full work-up happens at our centre, from our own lab to ultrasound and gastroscopy. Preparation is quick, there are no queues, and it is all in one building.
Recovery after bariatric surgery
Much of recovery depends on the individual, but minimally invasive laparoscopic techniques keep the rehab stage as short 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
You are permitted to sit up, stand and drink fluids in the first hours after surgery.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
7–14 days after surgery you can return to work, depending on how physical the job is.
Restrictions
The first weeks exclude bathhouse, sauna and intense physical exercise.
Diet
A staged diet is prescribed for 1–2 months, moving from liquids to solids so the stomach can adapt.
Pace
Patients who follow what specialists advise lose 10% of excess weight per month on average.
Stabilization
The final result comes in 1.5–2 years. By that point the patient has developed stable eating habits that stop the 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?
Though often confused, the two have fundamentally different goals. Bariatric surgery is a medical treatment of obesity and related illnesses; it changes the functioning of the digestive tract to address the causes of excess weight and metabolism. Plastic surgery reshapes the outer contours of the body and neither treats obesity nor affects metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
Our approach is modern laparoscopic technique: 4 small punctures of 5 to 15 mm. We use cosmetic sutures, so the marks turn almost invisible after healing.
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?
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, 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 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 Oklahoma City: methods, stages and package
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 Oklahoma City, the surgeon explains such trade-offs before any decision.
It begins with a surgeon's consultation: medical history, choice of method and a recovery plan. Patients from Oklahoma City then complete a work-up — blood and urine tests, biochemistry, HbA1c, coagulation, chest X-ray, ECG, abdominal and kidney ultrasound, leg vein Doppler and a required gastroscopy — plus consultations with a GP, endocrinologist, psychiatrist, cardiologist and, for women, a gynecologist.
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 Oklahoma City to arrange the next steps.
