It’s no secret that weight-loss surgery can help obese individuals reverse serious, life-threatening conditions such as type 2 diabetes, high blood pressure, high cholesterol, and other comorbidities. For over 20 years, medical evidence has shown that weight-loss surgery is more effective than non-surgical treatments at helping people lose weight and send type 2 diabetes into remission.
Now, a new review released in JAMA Surgery outlines the newest evidence and findings that support the efficacy of weight-loss surgery in terms of weight loss and type 2 diabetes remission. For the study, researchers compiled and reexamined evidence that was initially presented by the National Institutes of Health on weight-loss surgery and diabetes in 1991. Given the advances in technology that have taken place over the last two decades, medical researchers wanted to compare today’s evidence to that which was compiled 23 years ago.
While research proves that people who undergo bariatric surgery are able to lose between 20 and 30 percent of their body weight following surgery, the study authors point out that further research is needed to determine how long people are able to keep type 2 diabetes at bay. It’s also necessary to measure long-term health outcomes and look into how people are eating and managing their nutrition following surgery.
In 1991, Roux-en-Y gastric bypass surgery was the most popular, recommended form of bariatric surgery that was deemed safest and most effective for people with a BMI of 40 or more, and for those with a BMI of 35 who also suffered from one or more comorbidities. However, medical organizations now suggest that bariatric surgery is ideal for those with a BMI of 30 who suffer from type 2 diabetes and other comorbidities.
Today’s most popular form of bariatric surgery is sleeve gastrectomy, or gastric sleeve surgery, in which a portion of the stomach is removed and the remainder is stapled into a shape that resembles a small sleeve. In recent years, gastric sleeve surgery has been associated with fewer long-term complications.
