THE PROCEDURE
What is Gastric Sleeve Surgery?
Gastric sleeve surgery (sleeve gastrectomy) involves removing approximately 75-80% of the stomach, leaving a small, sleeve-shaped pouch. This dramatically reduces the amount of food you can eat at one time — and also reduces the production of ghrelin, the hunger hormone, making you feel significantly less hungry throughout the day.
At Estelux Istanbul, all gastric sleeve procedures are performed laparoscopically by Op. Dr. Aslan — a specialist bariatric surgeon who has dedicated his career exclusively to obesity and metabolic surgery since 2018, with over 2,000 successful sleeve gastrectomy cases.
50-70% excess weight loss
Most patients lose 50-70% of their excess body weight within 12-18 months of surgery.
Reduces hunger hormones
Ghrelin production is significantly reduced — making it easier to maintain a healthy diet long-term.
No foreign body implanted
Unlike gastric band surgery, no foreign device is implanted — reducing long-term complication risk.
Laparoscopic surgery
Performed through small incisions — minimal scarring, faster recovery and shorter hospital stay.
Improves health conditions
Significant improvement of type 2 diabetes, sleep apnoea, hypertension and joint pain in most patients.
Permanent results
With proper dietary habits and lifestyle changes, gastric sleeve delivers permanent, sustainable results.
