What is Sleeve Gastrectomy?

Sleeve Gastrectomy for weight loss is one of the restrictive operations for obesity performed at Garnet Health Medical Center – the other is Gastric Banding. Restrictive operations restrict food intake but do not interfere with the normal digestive process.

Sleeve Gastrectomy is the procedure in which a bariatric surgeon will remove approximately 75% of the stomach. The creation of a smaller stomach will physically restrict the amount of food consumption possible, but it also causes a significant decrease (by 90%) in the body’s release of ghrelin hormone (hunger hormone). This results in less food consumption, causing you to eat less and lose weight.

Following the surgery, what remains of the stomach is a narrow tube or sleeve which connects to the intestines. There are no nutritional deficiencies as a result of a Sleeve Gastrectomy because it does not affect the absorption of food, and the intestines are unaffected as well.

Most people who elect to have a restrictive surgery can no longer eat large amounts of food at one time. Although amounts vary, usually the person can eat only up to 1 cup of food without discomfort or nausea. It is very important that food is well chewed.

Types of Bariatric Surgery

The kind of surgery determined best for you will be based on your overall health, lifestyle, and a number of other factors that you and your doctor will access together. At Garnet Health Medical Center, we offer three types of weight-loss procedures:

Always ask your physician about all treatment options, as well as their risks and benefits.

Do I Qualify for Gastric Banding Weight Loss Surgery?

One of the methods used to measure obesity is Body Max Index (BMI). BMI is calculated by taking your weight in pounds and dividing it by your height in meters squared (BMI = kg/m2). Your BMI, along with your ideal body weight, are used to determine if you are a candidate for bariatric surgery.

  • BMI of 40 or greater – you are a candidate for bariatric surgery. A BMI of 40 or greater means that you are 100 pounds or more over your ideal body weight.
  • BMI of 35 – 39.9 - Surgery may be an option for you. If you are suffering from other serious health conditions you can be considered for bariatric surgery even if your BMI is less than 40 and you are less than 100 pounds above ideal weight. These conditions are referred to as comorbidities and can include, but are not limited to:
    • Type 2 diabetes
    • Heart disease
    • Respiratory problems
    • Sleep apnea
    • Heartburn and reflux
    • Depression
    • Infertility
  • BMI of 34.9 or under – You are not a candidate for bariatric surgery. We encourage you to talk to your doctor about your desire to lose weight. Your doctor can assist you in development weight loss goals and a plan to successful weight loss.
