Sleeve gastrectomy is a minimally invasive surgical procedure used in the treatment of obesity. During the operation, a large portion of the stomach is removed to create a smaller, tube-shaped stomach. This limits food intake, reduces appetite, and promotes significant weight loss. The procedure also leads to improvements in obesity-related conditions such as type 2 diabetes and high blood pressure.

It is suitable for individuals with a Body Mass Index (BMI) over 35 who have been unable to lose weight through diet and exercise alone. After the surgery, patients follow a structured nutrition plan beginning with liquid and pureed foods. Vitamin and mineral supplements may be necessary.

Sleeve gastrectomy is considered an effective and safe method due to its metabolic benefits and ability to support long-term weight control.
