What is Gastric Sleeve Surgery?
Gastric sleeve surgery, also known as sleeve gastrectomy, is a popular weight loss surgery designed to help individuals struggling with obesity. The procedure involves removing approximately 75-80% of the stomach, reducing it to a small, tube-like structure. This significantly limits food intake and promotes weight loss by altering hunger hormones like ghrelin.
With obesity rates rising worldwide—42.4% of American adults classified as obese in 2020—the demand for effective weight loss solutions like gastric sleeve surgery continues to grow.
Understanding Gastric Sleeve Surgery
How Does the Procedure Work?
- The surgery is performed laparoscopically, meaning small incisions are made to insert surgical instruments.
- The surgeon removes a large portion of the stomach, leaving a banana-shaped sleeve.
- Since the stomach is smaller, patients feel fuller faster, consuming fewer calories.
- The production of ghrelin, the hunger hormone, decreases, leading to reduced appetite.
Who is a Good Candidate?
Gastric sleeve surgery is recommended for individuals who:
- Have a BMI (Body Mass Index) of 40 or higher.
- Have a BMI of 35-39.9 with obesity-related health conditions like diabetes or hypertension.
- Have tried other weight loss methods without success.
