Sleeve Gastrectomy Surgery Results

Read below about outcomes after Sleeve Gastrectomy surgery: weight loss, impact on obesity related medical conditions (e.g. diabetes and high blood pressure), and complications.

Weight Loss After Sleeve Gastrectomy Surgery
Weight loss after Sleeve Gastrectomy surgery occurs over 1-3 years and averages approximately 50-70% of excess weight. This weight loss is somewhat less than the average Gastric Bypass weight loss and somewhat more than the average Gastric Banding weight loss. In the table below, the results of four studies were compiled to show average weight loss at different time intervals after surgery. Because Sleeve Gastrectomy is a relatively new operation, long-term weight loss outcomes (>3 years) have not yet been published.

Number of Gastric Sleeve Studies	4 (1083 patients)
Average Body Mass Index (BMI) in Study	39-49
% Excess Weight Loss at 12 months	58-59%
% Excess Weight Loss at 24 months	62-68%
% Excess Weight Loss at 36 months	66-69%

It is important to remember that these weight loss results are averages. Patients can lose more or less weight than the average. Good eating and exercise habits are necessary to maximize and maintain weight loss after Sleeve Gastrectomy Surgery, like with all weight loss surgeries. Patients who commit themselves to establishing and maintaining healthy eating habits and regular exercise after surgery generally lose more weight than those who don't.

Impact of Gastric Sleeve Surgery on Medical Problems
Many medical problems are associated with weight. Examples include diabetes, high blood pressure, sleep apnea, joint pain and arthritis, heartburn, asthma, depression, infertility, urinary stress incontinence, lower extremity swelling and headaches. The few published studies looking at the response of medical problems to Gastric Sleeve surgery show that obesity related problems tend to improve after surgery. In the table below results were compiled from three published studies.

Medical Condition	Resolved	Improved
Diabetes	47-81%	11-22%
Sleep Apnea	56-80%	7-31%
Hypertension	15-78%	7-25%
Hyperlipidemia	73%	5%
Joint Pains	85%	6%
GERD	70%	8%
Depression	67%	9%

Complications After Gastric Sleeve Surgery
As with any surgery, there is the potential for complications to occur. The published complication rates for the Gastric Sleeve operation are intermediate between complication rates for Gastric Bypass and Gastric Banding. See the table below for a compilation of complication results from five studies.

Complication	Percent of Patients
Death	0.39%
Pulmonary Embolism	<1%
Leak	0.8-1.8%
Nausea/Reflux	3-15%
Bleeding	1.4-2.5%
Readmission	2-4%
