Gastric Sleeve

Gastric sleeve surgeryalso called alaparoscopic sleeve gastrectomy,is the most common type of bariatric surgery.

During this procedure, approximately 80% of the stomach is surgically removed, including the area of the stomach that produces the most ghrelin, known as the hunger hormone.The stomach becomes much smaller and is shaped like a banana.

After the procedure, the stomach cannot hold as much food, and you experience less hunger. Overall, you will consume fewer calories and improve your metabolism, which can lead to weight loss and better blood sugar control.
