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
- Conventional weight-loss methods have failed in past attempts
Why don't diets and exercise work for everyone?
Many spend years on diets and exercise, and the body fights them all the way: metabolism slows, appetite grows, the lost kilos come back. As soon as it is clear that medication and diet changes alone cannot fundamentally improve the situation, bariatric surgery is the only effective way out.

Bariatric surgery methods at City Medical Centre
Sleeve gastrectomy
The operation involves removing most of the stomach and turning it into a narrow tube. As a result portions shrink a lot and the hunger hormone ghrelin falls, so the patient reaches fullness sooner and eats less.
Effectiveness: the method is intended for a BMI of 35 to 45. Excess weight goes down by 60–70% on average.
Specifics: the result is less durable than with bypass operations. If the diet is not followed, especially with high-calorie drinks and liquid food, the weight can return.
Roux-en-Y gastric bypass
The operation creates a small 50–70 ml stomach pouch at the top and connects it directly with the small intestine. Less food can be taken in, and fewer calories are absorbed because the path through the gut is shorter.
Effectiveness: considered the “gold standard” when BMI exceeds 45–50 with type 2 diabetes. Patients lose 75–85% of excess weight.
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)
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: similar to the classic Roux-en-Y bypass; up to 75–80% of excess weight is lost.
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)
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: 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.

City Medical Centre bariatric surgery centre
— your path
to confidence and harmony
City Medical Centre sees obesity comprehensively. From the first examination, each patient has a personal diagnostic program (lab and instrumental) built to identify every disorder present in the body.
A method matched to your goal
Each patient gets an individually chosen surgical method from our doctors. Before a decision, they look at your health, weight history and associated conditions to recommend the most fitting surgical treatment.
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 after bariatric surgery
Each patient recovers differently, but minimally invasive laparoscopic techniques keep rehabilitation as brief as possible.
Duration
Observation at the clinic lasts 1 to 5 days, based on how extensive the surgery is and on related conditions.
Activity
In the first hours post-op, sitting up, standing and drinking fluids are fine.
Wound care
Absorbable sutures are used; they dissolve on their own.
Work
Depending on the physical demands of your job, you can return to work 7–14 days after surgery.
Restrictions
During the first weeks, stay away from bathhouses, saunas and intense exercise.
Diet
A staged diet is prescribed for 1–2 months, moving from liquids to solids so the stomach can adapt.
Pace
With the specialists' advice followed, average loss is 10% of excess weight per month.
Stabilization
In 1.5–2 years the final result is reached, and by then the patient's stable eating habits prevent the weight coming back.
Important! Specialists from City Medical Centre supervise recovery and provide psychological and medical support at each weight-loss stage.

Frequently asked questions
about bariatric surgery at CMC
Bariatric vs plastic surgery: what's the difference?
Many confuse the two, yet their purposes are fundamentally different. Bariatric surgery is medicine's treatment for obesity and related diseases: it changes how the digestive tract operates and addresses the causes of excess weight and metabolism. Plastic surgery reshapes outer contours of the body without treating obesity or affecting metabolism.
How soon can I return to work and normal life?
Will there be visible scars?
Modern laparoscopic technique allows the operation through 4 small punctures of 5 to 15 mm. Cosmetic sutures make the marks almost invisible when fully healed.
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 performs four main types of bariatric surgery: sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass (MGB) and SADI-S duodeno-ileal bypass. Each method is chosen individually based on BMI, related conditions and the patient's goals.
Can I plan a pregnancy after surgery?
Pregnancy is an option after bariatric surgery, but doctors advise waiting at least 12–18 months. By then the body has stabilized, weight has reached target values and nutritional status has normalized.
Do I need to take vitamins after surgery?
Yes, vitamins after bariatric surgery are a must. Because the digestive anatomy changes, the body absorbs some nutrients less well, so regular vitamin and mineral supplements become a permanent part of the patient's life.
Can the weight come back?
Weight regain is possible after bariatric surgery but very unlikely provided you follow the doctor's advice. Eat properly, avoid high-calorie drinks and keep up regular follow-up with City Medical Centre specialists.

When bariatric surgery in Onitsha makes sense
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. Onitsha patients receive a personal assessment against these points.
Step one: consultation. Step two: laboratory and instrumental tests, gastroscopy and specialist reviews. Step three: surgery through small punctures by a permanent team, not a duty shift. Step four: 1–5 days in the ward with meals and nursing. Step five: a staged diet and a year of follow-up. People in Onitsha follow this route from start to finish.
If you are comparing bariatric surgery options in Onitsha, 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.
