Procedure

How the treatment works

The sleeve is performed under general anesthesia and usually takes between 60 and 90 minutes. Every operation is preceded by a full day of pre-operative testing and consultations at our partner hospital in Istanbul.

1

Pre-Op Testing & Consultations

You complete blood tests, ECG, chest imaging, abdominal ultrasound and an endoscopy, then meet your surgeon, anesthesiologist and dietitian. Surgery is confirmed only when all results are cleared.

2

General Anesthesia & Keyhole Access

Once you are asleep, the surgeon makes four to five small incisions and inserts a camera and fine instruments. Laparoscopic access means less pain, smaller scars and a quicker return to your feet.

3

Sleeve Creation & Stomach Removal

Using a sizing tube as a guide, about 80% of the stomach — including the outer curve and the fundus — is divided with surgical staplers and removed. What remains is a narrow sleeve holding roughly 100–150 millilitres.

4

Leak Test & Reinforcement

The staple line is tested for leaks with a dye or air test and reinforced where needed. This meticulous check is one of the most important safety steps of the operation.

5

Hospital Recovery

You wake in a private room and are walking within hours. Over three to four nights the team manages pain, starts your liquid diet and monitors your recovery before hotel discharge.

Candidacy

Who is suitable?

The gastric sleeve suits a wide range of patients with obesity, from those having their first bariatric operation to those unsuitable for bypass. Candidacy is always confirmed by our surgical team after your pre-operative tests.

Adults with a BMI of 40 or above Adults with a BMI of 35–40 with obesity-related conditions such as type 2 diabetes, hypertension or sleep apnea Selected patients with a BMI of 30–35 and poorly controlled metabolic disease, after specialist evaluation Those who have tried supervised diet and exercise programmes without lasting success Patients who prefer a simpler operation without intestinal rerouting Patients prepared to commit to long-term dietary changes and follow-up, and without severe untreated reflux
Recovery

Your recovery timeline

1
Days 1–4
You recover in hospital with early walking, breathing exercises and a supervised clear-liquid diet. Pain is generally well controlled and drains, if used, are removed before discharge.
2
Week 1
You rest at your hotel and attend a final check-up before flying home, usually around day seven. Your staged nutrition plan, medications and supplement schedule are all provided.
3
Month 1
You progress from liquids to purees and soft foods. Most patients return to desk work within two weeks and notice the first significant weight loss.
4
Month 3
A normal high-protein, portion-controlled diet is established and full exercise is resumed. Weight loss is typically at its fastest during months two to six.
5
Months 12–18
Most patients reach their stable result in this period. Annual reviews, blood tests and dietitian check-ins continue so your result is protected for the long term.
FAQ

Gastric Sleeve — your questions answered

Most patients lose around 55–70% of their excess weight within 12–18 months, with individual results depending on starting weight, age and adherence to the programme. Obesity-related conditions such as type 2 diabetes and sleep apnea also commonly improve significantly.

Yes. The removed portion of the stomach does not grow back, so the operation should be considered permanent. The remaining sleeve can stretch slightly over years, which is why the dietary habits built with our team matter so much for lasting results.

Most patients report the opposite. The part of the stomach removed produces most of the ghrelin hormone that drives hunger, so appetite genuinely decreases. Combined with the smaller stomach volume, small meals become naturally satisfying.

As with any major surgery there are risks, including bleeding, staple-line leak and reflux; serious complications are uncommon in experienced hands. Our surgeons perform high volumes of sleeve operations in accredited hospitals with intensive-care backup, and every patient completes thorough pre-operative testing to minimise risk.

Plan for about seven nights: one for tests, three to four in hospital and the remainder at your hotel before your fit-to-fly check. The all-inclusive package covers tests, surgery, hospital stay, medications, hotel, VIP transfers, an interpreter and lifelong remote follow-up.

Yes, though usually fewer than after a bypass. A daily multivitamin, plus vitamin B12 and vitamin D as guided by your blood results, is standard. We review your levels at scheduled remote follow-ups and adjust your supplements accordingly.

Yes — fertility often improves as weight normalises. We advise waiting 12–18 months after surgery before conceiving, so your weight is stable and your nutrition is fully optimised for a healthy pregnancy.

The sleeve is simpler, keeps your intestines untouched and requires lighter supplementation; the bypass offers stronger effects on diabetes and reflux. The right choice depends on your BMI, medical conditions and endoscopy findings — our surgeons review everything with you honestly before any decision is made.
