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.
Your weight at each stage of your journey depends on several factors, such as surgeon’s skills, starting weight, your diet or health-related issues. However, here is an average sleeve Weight Loss Timeline at 3, 6, 9, 12 and 18 months milestones:
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.
Expected Rate of Weight Loss in 6 Months
At this stage of your journey, your weight loss continues but at a lower pace. In 6 months after the surgery, you will lose an average of 45-55%* of your body excess weight – an average of one to two pounds per week.
Expected Rate of Weight Loss in 1 Year
You should be getting close to your goal weight in one year after sleeve surgery, of course not everyone loses all the excess weight in this stage. You will lose an average of 65-70%* of your body excess weight.
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 Study looked at different weight loss operations to see how each of them compared regarding the amount of weight loss. The study found that when patients were followed up at one, two, and three years after weight loss surgery, those who specifically 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.
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.
At Mexico Bariatric Center®, we see patients more often lose 80% to 100% of their excess weight within the first two years after surgery. 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.
