How Much Do I Lose After Gastric Sleeve?

In order to determine the amount of weight you will lose after gastric sleeve surgery, we created a weight loss timeline specific to your weight. Here is the guideline to calculate your weight loss. Simply follow steps 1 through 3 to get an estimate of how much you will lose weight:

  1. Find out your Ideal Weight from this table here.
  2. Excess Weight = Current Weight – Ideal Weight
  3. Expected Weight Loss = Excess Weight X 0.65 (65%-70% is an average)

Your new weight is going to be:

New Weight After Surgery = Current Weight – Expected Weight Loss

Gastric Sleeve Weight Loss Example

A female who is 5′ 4” and weighs 250 lbs with medium frame size.

  • Her ideal weight from the table is 120 lbs.
  • Excess Weight = 250 lbs – 120 lbs = 130 lbs
  • Expected Weight Loss (Average) = 130 lbs X  0.65 = 85 lbs

She can expect to lose on average 85 lbs within the first year after gastric sleeve.

Studies on Weight Loss After Gastric Sleeve

Studies have been performed to depict both short-term and long-term success rates after gastric sleeve surgery. These studies look at how much weight was lost and how long that weight was kept off. Most gastric sleeve patients lose up to 60% of their excess weight in a year and up to 70% of it in two years. Resolution of comorbidities occurs in just one to two years following weight loss surgery.

One Swiss study learned that patients kept off at least 57% of their excess weight five years following their surgery. Long-term success shows significant improvements in the risk of stroke or heart disease and a decrease in countless obesity-related medical conditions.

Studies for the Long-Term Weight Loss

The U.S. National Library of Medicine Study looked at different weight loss procedures to see how all of them compare regarding weight loss. The study found that when patients were followed up within 1, 2 and three years after surgery, those who had gastric sleeve surgery had more of a considered long-term weight loss chart than other surgery types.

In the gastric sleeve weight loss chart, just 6.3% of the patients had any complications at all. 60% of the patients studied had experienced major weight loss in just one to two years (18 months) following their surgery.

Another study, the Surgery for Obesity and Related Diseases Study, looked at how successful gastric sleeve surgery was at helping patients keep weight off for an extended period. It looked at the results of patients who had the surgery five years ago. Things such as total weight loss, how quickly weight was lost, quality of life and complications were all evaluated.

The average amount of excess weight loss for those studied in this professional study was 61.5% after just one year and 61.1% after just two years. The average for all five years for 57.4 percent (pretty close to the expected weight loss surgeons usually tell patients at their consultation).
