Sleeve Gastrectomy Surgery Outcomes

Sleeve Gastrectomy Weight Loss Results

Our Laparoscopic Gastric Sleeve patients average 65% excess weight loss (EWL) 1 year after surgery, and 77% EWL 2 years after surgery (see table below). Our results compare favorably to the best published studies on weight loss after Sleeve Gastrectomy Surgery, which generally show between 60-80% EWL after surgery.

The weight loss results discussed on this page are averages - individual patients can lose more or less weight than the average (see Achieving Weight Loss Success section below).

Calculating Excess Weight Loss after Sleeve Gastrectomy

Excess weight is the amount of weight over ideal weight. Ideal weights are published in the Metropolitan Life Insurance height-weight tables. These tables display weight ranges for small, medium, and large frame sizes. Ideal weight is considered to be the middle weight in the medium frame size range. To calculate the percentage of excess weight loss (%EWL) divide weight lost by maximum excess weight and multiply by 100. The tables include one inch of height for shoes, so one inch needs to be added to actual height to see the correct weight range.


Achieving Long-Term Weight Loss Success

Successful long-term weight loss after Sleeve Gastrectomy Surgery requires both a well-performed quality operation and appropriate ongoing eating/exercise habits. For this reason choice of surgeon and program influences patient outcomes.

Our Orange County Sleeve Gastrectomy Program focuses on two things: (1) providing excellent surgery to give our patients a safe and highly effective tool for weight loss, and (2) providing quality education, follow-up, and support to help our patients establish the eating/exercise habits that will enable long-term weight loss success. The result of this focus has been excellent weight loss results as described above.
