Permanent weight loss solution — sleeve gastrectomy
What is Gastric Sleeve Surgery?
Gastric sleeve surgery (sleeve gastrectomy) permanently removes approximately 75-80% of the stomach, creating a banana-shaped sleeve. This reduces food intake, eliminates hunger hormone (ghrelin) production, and delivers 60-80% excess weight loss within 18 months. Turkey is the world leader in bariatric tourism with JCI-accredited hospitals offering all-inclusive packages at 60% lower cost than the UK or US.
