Turkey has become one of the most popular destinations for weight loss surgery, not just because of cost, but also because of the high level of medical expertise and modern clinics available. Recent studies show that patients lose an average of 60–70% of their excess weight within the first year after surgery, and more than 90% report being satisfied with the results and improvements in quality of life (SpringerLink, 2024). Choosing gastric sleeve surgery is a big decision, and picking the right surgeon makes all the difference. At Experts Medical, we know that the choice of surgeon is the most important step - because while success rates are high, complications like leaks or strictures can happen in less experienced hands. That’s why we’ve already done the screening for you. We selected the best specialists based on the real outcomes of more than 12,000 patients who had treatments and surgeries through us. With this list, you can move forward with confidence, knowing you’re choosing from surgeons who consistently deliver safe procedures and lasting results.

Gastric Sleeve Surgery and What Patients Experience
Gastric sleeve surgery has become one of the most common weight loss procedures worldwide, and Turkey is no exception. The operation itself is fairly straightforward: surgeons remove about 70–80% of the stomach and reshape it into a sleeve-like tube, which helps patients feel full with much less food. It’s done laparoscopically in most cases, meaning smaller cuts, less pain, and usually a quicker recovery.
But what really matters to patients is not just the surgery - it’s the results. Research shows that people lose on average 60–70% of their excess weight within the first year after sleeve gastrectomy. A large multicenter study also found that more than 90% of patients report being satisfied with the decision two years after surgery, with clear improvements in overall health and quality of life (SpringerLink, 2024). Turkish clinics that specialize in bariatrics often share similar numbers, when it comes to long-term weight loss and diabetes control.
Of course, no surgery is risk-free. Complications like bleeding, strictures, or staple line leaks can happen, though in experienced hands they’re relatively rare - serious issues occur in less than 1% of cases in most accredited centers (Annals of Laparoscopic and Endoscopic Surgery, 2021). And while some patients regain a portion of the weight over time, regret rates remain very low, with studies showing the majority would choose the surgery again if given the option.
