Gastric sleeve surgery is an effective tool for obese individuals to lose weight and keep it off long-term. Studies have been performed to depict both short-term and long-term success rates after gastric sleeve surgery.

Most gastric sleeve patients lose an average of 65-70% of their excess weight (EW) in a year – an average of 2-3 pounds per week. Patients lost up to 75% of their EW 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.

Expected Rate of Weight Loss in 3 Months

You will follow the post-op diet and gradually transition from liquid to solid food. As a result, you can expect a quick surge in your weight loss in the first 3 months following surgery. You could lose an average of 25-35%* excess weight – between 30 and 40 pounds.

Long-Term Expected Weight Loss

The U.S. National Library of Medicine 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.

Patients followed up at one, two, and three years after weight loss surgery. Those who underwent sleeve gastrectomy had a significantly improved long-term weight loss chart than other obesity-treating procedures. Also within the gastric sleeve weight loss chart, 60% of the patients studied had experienced major weight loss between one and two years (18 months) post-operation. Out of all candidates, only 6.3% of all patients had any complications whatsoever.

Mexico Gastric Sleeve Weight Loss

At Mexico Bariatric Center®, we see patients more often lose 80% to 100% of their excess weight within the first two years after vertical sleeve gastrectomy. Our data show a strong correlation between the amount of excess weight loss with following the post-op diet, exercise routine, and healthy lifestyle habits.

We also see significant improvements and/or remission in obesity-related comorbidities such as type II diabetes, high blood pressure, high cholesterol, and obstructive sleep apnea.
