Surgery is prescribed only when clear criteria are met
The main way to assess the degree of obesity is BMI. It is body weight (kg) divided by height squared (m²). Generally, surgery is justified with BMI above 40, or above 35 combined with serious related conditions. Lower values may sometimes be considered for surgery too, when non-surgical measures have failed.
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.

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: the method fits a BMI between 35 and 45. Average loss is 60–70% of excess weight.
Specifics: bypass operations give a more durable result. Should the diet be ignored, especially with high-calorie drinks and liquid food, weight can return.

Roux-en-Y gastric bypass
A small pouch of 50–70 ml is created from the upper stomach and connected directly to the small intestine. Food intake is limited, and fewer calories are absorbed because food travels a shorter path through the gut.
Effectiveness: regarded as the “gold standard” for a BMI over 45–50 with type 2 diabetes. Loss of excess weight reaches 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)
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: a shorter operation and quicker recovery. The procedure can technically be reversed, but the single anastomosis carries a risk of bile reflux.

Single anastomosis duodeno-ileal bypass (SADI-S)
SADI-S is an up-to-date combined technique joining the strengths of sleeve gastrectomy and intestinal bypass. There are two stages: the stomach is first made into a narrow tube, and then the small intestine is rerouted to exclude most of it from active digestion.
Effectiveness: one of the most potent bariatric operations; excess weight loss hits 80–90% and the result is long-lasting.
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.

At City Medical Centre, obesity is approached as a whole. After the initial examination each patient is given an individual diagnostic program, both lab and instrumental, to find all disorders in the body.

A method matched to your goal
The surgical method is chosen by our doctors on an individual basis. They first review your health, your weight history and related conditions, then offer the surgical treatment that suits you 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
City Medical Centre's bariatric operations are laparoscopic, so recovery is much shorter. On day one most patients are already up and moving, and within a week they return to normal life.

Full diagnostics on site
There is no need to rush between clinics. Our centre offers your entire work-up — our own lab, ultrasound, gastroscopy. Preparation goes quickly, with no queues, all in one building.
The pace of recovery is largely personal, but minimally invasive laparoscopic techniques shorten rehabilitation as much as possible.

Duration
Observation at the clinic lasts 1 to 5 days, based on how extensive the surgery is and on related conditions.
Activity
Within the first hours after surgery you may sit up, stand and drink fluids.
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
In the first weeks, avoid the 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
On average, patients who follow the specialists' advice lose 10% of excess weight a month.
Stabilization
Full results are reached in 1.5–2 years. By then, stable eating habits are in place that prevent the weight from coming back.
Important! City Medical Centre specialists supervise your recovery and support you psychologically and medically at every stage of weight loss.

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?
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?
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?
Getting pregnant after bariatric surgery is possible, but doctors advise waiting at least 12–18 months, so the body can stabilize, weight can reach target values and nutritional status can normalize.
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?
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.

Roux-en-Y gastric bypass creates a small 50–70 ml pouch at the top of the stomach and connects it straight to the small intestine. It is considered the gold standard for a BMI over 45–50 with type 2 diabetes, bringing excess weight loss of 75–85%. Anyone researching bypass in Mombasa should know that it requires lifelong vitamin and mineral supplements.
Eating changes in stages. A staged diet lasts 1–2 months, moving from liquid to soft to solid food so the stomach can adapt, with the focus on protein and limited high-calorie, fatty dishes.
