Sleeve gastrectomy is a type of bariatric or weight loss surgery. During the procedure, your doctor removes about 80% of your stomach. The intestines are not altered in any way, so digestion flows in the same direction as it was before surgery.
Sleeve gastrectomy works by reducing the size of your stomach and changing hormone levels.
Making your stomach smaller limits the amount of food you can consume at one time, so you feel full quickly, take in fewer calories, and lose weight. It also reduces ghrelin -- the hormone produced in the stomach that makes you feel hungry -- so many patients find that their appetite decreases following sleeve gastrectomy.
Additionally, other metabolic changes in other hormones affect hunger, satiety, appetite, and blood sugar control that helps improve weight loss.
Patients seeking bariatric surgery often have a history of trying to lose weight with other methods that were unsuccessful.
Your physician may recommend sleeve gastrectomy if you have:
To achieve optimal results, you’ll also need to commit to following the recommended eating and exercise plan, along with the follow-up plan after you have sleeve gastrectomy.
Many patients lose 60-70% of their excess body weight on average within the first to two years after sleeve gastrectomy. Your total weight loss, however, depends on a variety of factors like your preoperative weight, age, sex, and your ability to follow a healthy diet following your surgery.
Obesity increases your risk for chronic health conditions such as diabetes, high blood pressure, high cholesterol, and obstructive sleep apnea. These health problems may resolve or significantly improve in more than 75% of patients who have sleeve gastrectomy.
Sleeve gastrectomy may improve your glucose metabolism regardless of the amount of weight you lose because of its effect on hormones. It’s estimated that type 2 diabetes may go into remission in more than 60% of those undergoing sleeve gastrectomy.
Sleeve gastrectomy is a minimally-invasive procedure performed through small incisions in the abdomen. A camera is inserted through one incision to provide a magnified view which allows the surgeon to perform the procedure using thin surgical instruments which they insert through the other incisions.
