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.
