Frequently Asked Questions

Find answers to common inquiries.

All questions
Am I a suitable candidate for bariatric surgery?+

Suitability is decided after a medical evaluation. Surgery is generally considered for a BMI of 40 or above, or 35–39.9 alongside weight-related conditions such as type 2 diabetes or high blood pressure. For lower BMIs, non-surgical options may be more appropriate.

How long do I need to stay in Türkiye?+

It depends on the procedure. For most bariatric surgeries a stay of around 5–7 days is typical, allowing time for the operation, initial recovery and post-operative checks before you fly home.

What is the difference between gastric sleeve and gastric bypass?+

A sleeve gastrectomy reduces the size of the stomach, while a gastric bypass both reduces the stomach and reroutes part of the digestive tract. The most suitable option is determined during consultation based on your health profile.

How is follow-up handled after I return home?+

We provide ongoing support after you return home, including remote follow-up, nutritional guidance and access to our team, together with the recommended vitamin and mineral supplementation.
