Surgery is prescribed only when clear criteria are met
BMI is the principal gauge of how advanced obesity is, found by dividing body weight (kg) by height squared (m²). Typically, a BMI above 40 — or above 35 with serious related conditions — justifies surgery. Some patients with lower values are considered for surgery too, if non-surgical options 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
During surgery the surgeon removes most of the stomach, turning it into a narrow tube. This greatly reduces portion size and lowers ghrelin, the hunger hormone, so the patient feels full much faster 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: 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 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: the operation is considered the “gold standard” for a BMI over 45–50 with type 2 diabetes. Excess weight loss reaches 75–85%.
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)
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: like the classic Roux-en-Y bypass, it helps patients lose up to 75–80% of excess weight.
Specifics: surgery takes less time and recovery is faster. It can technically be reversed; the single anastomosis, though, poses a risk of bile reflux.

Single anastomosis duodeno-ileal bypass (SADI-S)
As a modern combined technique, SADI-S brings together the benefits of sleeve gastrectomy and intestinal bypass. Its two stages: making the stomach into a narrow tube, then rerouting the small intestine so the majority of it is excluded from active digestion.
Effectiveness: among the most powerful bariatric operations — excess weight loss reaches 80–90% with a lasting result.
Specifics: the reduced stomach lowers appetite once the ghrelin-producing zone is removed, and routing food past a section of intestine limits how many calories are absorbed. Suitable for super obesity (BMI over 50), severe type 2 diabetes, or as a second stage after an ineffective sleeve.

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
Our doctors match the surgical method to each individual patient. They review your health, weight history and accompanying conditions before deciding, to offer you the most appropriate surgical treatment.

Support that stays in touch
City Medical Centre's team stays with you once surgery is over. During the first year, specialists monitor your weight loss and test results and answer any questions on diet and recovery.

Fast recovery
At City Medical Centre, bariatric operations are laparoscopic, which significantly shortens recovery. Most patients are up and active on day one and return to normal life within a week.

Full diagnostics on site
No need to travel between clinics. From our own lab to ultrasound and gastroscopy, the centre has all you need for your work-up. Preparation is fast, without queues, in one building.
The pace of recovery is largely personal, but minimally invasive laparoscopic techniques shorten rehabilitation as much as possible.

Duration
Patients stay under observation at the clinic 1 to 5 days, depending on how extensive the surgery is and related conditions.
Activity
In the early hours after surgery you can already sit up, stand and have fluids.
Wound care
Absorbable sutures are used; they dissolve on their own.

Work
You may get back to work 7–14 days post-surgery, depending on the physical load of your job.
Restrictions
Bathhouse, sauna and intense physical exercise are banned in early weeks.
Diet
A staged diet is prescribed for 1–2 months — from liquids to solids to let the stomach adapt.

Pace
On specialists' advice, patients typically lose an average of 10% of excess weight per month.
Stabilization
The end result is achieved in 1.5–2 years, when the patient already has stable eating habits that prevent weight regain.
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?
Modern laparoscopic technique is what we use. Just 4 small punctures of 5 to 15 mm are needed for the operation. Cosmetic sutures mean the marks are nearly invisible after healing.
What diet do I need to follow?
Eating changes gradually: liquid food first, then soft, then solid. The focus is protein, with high-calorie, fatty food kept to a minimum.
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?
Pregnancy is possible after bariatric surgery; doctors advise waiting no less than 12–18 months. This gives the body time to stabilize, for weight to reach target values and nutritional status to normalize.
Do I need to take vitamins after surgery?
Yes, vitamins become essential after bariatric surgery. The changed digestive anatomy lowers absorption of some nutrients, so regular vitamin and mineral supplements turn into 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.

SADI-S combines a sleeve with intestinal bypass in two stages and is one of the most powerful bariatric operations, with 80–90% excess weight loss and a long-lasting result. It suits super obesity with a BMI over 50, severe type 2 diabetes, or a second stage after an ineffective sleeve. Anyone in Athens in these situations can discuss it at a consultation.
It begins with a surgeon's consultation: medical history, choice of method and a recovery plan. Patients from Athens 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.
Weight loss is written into the contract, and the package includes every stage: consultation, diagnostics, the operation, inpatient care with meals and a year of support. A personal coordinator guides you from day one. To begin, patients from Athens leave a request on the page or message the clinic, then receive a free consultation with a bariatric surgeon.
