Gastric Sleeve (Sleeve Gastrectomy) in Turkey

Most nationalities can obtain a Turkish e-visa online before travel, which permits a stay of up to ninety days within any one-hundred-and-eighty-day period. Turkey does not have a dedicated medical visa category, so the standard tourist or e-visa applies to most medical tourists. Patients should check current visa requirements for their specific nationality.

Turkey uses the Turkish Lira (TRY). Major private hospitals and internationally oriented clinics typically accept payment in euros, US dollars, or pounds sterling in addition to Lira, which is useful for patients who have budgeted in their home currency. Currency exchange facilities are widely available.

English is spoken well at JCI-accredited hospitals and the larger internationally oriented private clinics in Istanbul, where dedicated international patient coordinators handle communication. In smaller clinics and hair transplant centres, English proficiency varies and patients should confirm language support arrangements before booking.

Check whether the facility holds Ministry of Health health tourism certification or JCI accreditation, both of which indicate baseline quality standards. Independently verify the surgeon's medical licence through the Turkish Medical Association, and be cautious of clinics that communicate primarily through social media, offer unusually low prices, or cannot provide verifiable before-and-after outcomes data.

Patients can file complaints with the Turkish Ministry of Health or Turkish Medical Association. Civil litigation is available but pursuing a case from abroad is practically and financially challenging. The 2014 mandatory malpractice insurance law means physicians should carry insurance, but claim resolution can be slow. Choosing a reputable, accredited facility substantially reduces the likelihood of adverse outcomes.

Flying timelines depend on the procedure performed. For hair transplants, most patients fly home within three to five days. For surgical procedures, patients should remain for the post-operative review and until cleared to fly by the treating team. DVT risk from immobility during flights is a genuine concern for all surgical patients and should be discussed with the surgical team.

Before leaving Turkey, obtain comprehensive written discharge notes, operative records, and any implant or product documentation. Identify a local physician or specialist who is willing to provide follow-up care before travelling, and share the Turkish records with them at the first appointment. Many Turkish hospitals have dedicated aftercare coordinators who can respond to email or telephone queries.

Standard travel insurance generally excludes complications from planned elective procedures. Medical tourism-specific insurance — available from specialist providers — covers both the procedure and post-operative complications including emergency care and repatriation. This should be purchased before travel and the policy read carefully for exclusions.

Istanbul has an extensive public transport network including metro, tram, and ferry services, and taxis and ride-hailing apps are widely available. Many clinics offer airport transfers and can arrange transport to appointments. Patients with limited mobility post-procedure should confirm accessible transport options with their clinic or hotel in advance.

The main risks are choosing a clinic where graft extraction and placement are performed by unqualified technicians rather than medical staff, and procedures conducted in facilities not registered with the Ministry of Health. Patients should confirm in writing who performs each stage of the procedure and verify that the clinic holds appropriate health tourism certification.

Most patients lose fifty to seventy per cent of their excess body weight within twelve to eighteen months of surgery. The exact amount depends on starting weight, adherence to dietary guidelines, and lifestyle factors including physical activity.

No. Sleeve gastrectomy permanently removes approximately eighty per cent of the stomach, and this cannot be reversed. However, in cases where results are insufficient, the procedure can be converted to a gastric bypass or duodenal switch in a subsequent operation.

Yes. Because the reduced stomach size limits nutrient absorption and the volume of food that can be consumed, lifelong supplementation with a multivitamin, vitamin B12, calcium, vitamin D, and iron is essential. Deficiencies develop gradually and must be monitored with regular blood tests.

The sleeve can gradually expand over time, particularly with persistent overeating, though it will not return to its original size. Significant stretching is one factor that contributes to weight regain in some patients several years after surgery, alongside changes in eating habits.

Significant weight loss often results in loose or redundant skin, particularly in the abdomen, thighs, and upper arms. The extent depends on the amount of weight lost, age, skin elasticity, and genetics. Body contouring surgery can address this but is a separate procedure.

The procedure is performed under general anaesthesia and is not painful during surgery. Post-operative discomfort — typically described as soreness at the port sites and shoulder-tip pain from the gas used in laparoscopy — is usual for the first few days and is managed with analgesics.

Most programmes require a BMI of 40 or above, or a BMI of 35 or above combined with at least one obesity-related condition such as type 2 diabetes, hypertension, or sleep apnoea. A psychological evaluation and nutritional assessment are typically required before approval.

Many patients experience significant improvement or complete remission of type 2 diabetes following sleeve gastrectomy, often within weeks of surgery — before major weight loss has occurred. This is attributed to hormonal changes rather than weight loss alone, though results vary and the condition may return over time.
