Gastric Sleeve Weight Loss Timeline, Chart – What You Can Expect!

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!

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. The 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.

Weight Loss Percentage Rate After Gastric Sleeve

Here is an average sleeve Weight Loss Timeline at 3, 6, 9, 12, 18, and 24 months. Several factors can affect your weight loss results after gastric sleeve surgery. These include your starting weight, diet, lifestyle, age, race, health-related issues, and the surgeon’s skills.

Expected Rate of Weight Loss in 3 Months

You will follow the post-op diet and gradually transition from liquid to solid foods. 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.

Expected Rate of Weight Loss in 6 Months

At this stage of your journey, your weight loss continues but at a lower pace. You can expect to lose approximately 45-55% of your excess body weight in 6 months after your bariatric procedure. This is an average weight loss of one to two pounds per week.

Expected Rate of Weight Loss in 1 Year

One year after sleeve surgery, patients typically lose 65-70%* of their excess body weight. You should be getting close to your goal weight but not everyone loses all the excess weight in this stage.

Expected Rate of Weight Loss in 18 Months

Expect your weight loss to level off in 1.5 years after undergoing the sleeve procedure. In general, you can expect to lose 70-80%* or more of your body excess weight in 18 months.

Long-Term Expected Weight Loss

The U.S. National Library of Medicine studied the long-term success of gastric sleeve surgery in helping patients maintain weight loss. Their studies looked at the results of patients five years after their surgery. They evaluated total weight loss, how quickly weight was lost, quality of life, and complications.

Patients followed up at one, two, and three years after bariatric surgery. Those who underwent the vertical sleeve gastrectomy had a significantly improved long-term weight loss chart than other obesity-treating procedures. 60% of the patients studied had experienced major weight loss between 12 and 18 months post-operation. Out of all candidates, only 6.3% of all patients had any complications whatsoever.

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.
