Surgery is prescribed only when clear criteria are met
BMI serves as the chief indicator of obesity severity. Divide body weight (kg) by height squared (m²) to calculate it. Surgery is normally justified at BMI above 40, or above 35 with serious accompanying conditions. In selected cases it is considered at lower values as well — if non-surgical methods did not help.
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
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: suitable for a BMI of 35 to 45. Patients lose 60–70% of their excess weight on average.
Specifics: the outcome lasts less reliably than after bypass. Weight can come back if the diet is neglected, above all with high-calorie drinks and liquid food.

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: with a BMI over 45–50 and type 2 diabetes, this is the “gold standard”. Excess weight loss is as high as 75–85%.
Specifics: compared with other bariatric methods, the result is more stable. Conditions like diabetes and hypertension commonly go into remission. The altered digestive anatomy requires lifelong vitamin and mineral supplements.

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: on par with the classic Roux-en-Y bypass — patients shed up to 75–80% of excess weight.
Specifics: shorter operating time and faster recovery. Though technically reversible, it carries a risk of bile reflux due to the single anastomosis.

Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S combines the advantages of sleeve gastrectomy and intestinal bypass in one modern technique. It is done in two stages: stage one makes the stomach a narrow tube; stage two reroutes the small intestine so that most of it is excluded from active digestion.
Effectiveness: ranks among the most powerful bariatric operations: up to 80–90% of excess weight lost, with lasting results.
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.

City Medical Centre treats obesity comprehensively. Following the first examination, every patient receives a personal diagnostic program (lab and instrumental) to detect every disorder 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
The City Medical Centre team stays with you after surgery. Throughout the first year, specialists track your weight loss, monitor your tests and answer all questions about 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
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 is mostly down to the individual; still, minimally invasive laparoscopic methods keep rehabilitation 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
In the first hours after the operation you can sit up, stand and drink fluids.
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
No bathhouse, sauna or intense physical exercise during the first weeks.
Diet
The prescribed staged diet runs 1–2 months, shifting from liquids to solids so the stomach adapts.

Pace
Following the specialists' advice, patients lose on average 10% of excess weight per month.
Stabilization
The final result is seen after 1.5–2 years. In that time the patient builds stable eating habits that keep the weight from returning.
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?
Our surgeons use modern laparoscopic technique: the operation goes through 4 small 5 to 15 mm punctures. With cosmetic sutures, the marks become almost invisible once healed.
What diet do I need to follow?
Diet changes happen in stages, from liquids to soft food and then solids. It centers on protein and limits high-calorie, fatty food.
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?
Bariatric surgery does not rule out pregnancy, but doctors suggest waiting 12–18 months or more. During that time the body settles, weight reaches target values and nutrition status normalizes.
Do I need to take vitamins after surgery?
Yes, after bariatric surgery vitamins cannot be skipped. As the digestive anatomy changes, some nutrients are absorbed less well, making regular vitamin and mineral supplements a permanent feature of the patient's life.
Can the weight come back?
Regaining weight after bariatric surgery is possible, yet very unlikely when you stick to the doctor's advice. The keys are proper nutrition, no high-calorie drinks and regular check-ups with City Medical Centre specialists.

Sleeve gastrectomy turns most of the stomach into a narrow tube, reducing portion size and levels of ghrelin, the hunger hormone. It suits a BMI of 35 to 45, with patients losing on average 60–70% of excess weight. For anyone from Warri with a higher BMI or type 2 diabetes, a bypass may fit better; the surgeon compares options at the consultation.
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 Warri return to their normal routine within a week, following a diet plan and avoiding saunas and heavy exercise for the first weeks.
Before spending on another diet, get a professional assessment. A short no-cost talk with the surgeon, about a quarter of an hour, shows whether your BMI and related conditions justify surgery. If they do, one package takes you through tests, the operation, care in the ward and follow-up, with the weight loss result set in a contract. Residents of Warri can apply online.
