The study showed that only 1.8 percent of patients developed diabetes in the five years after weight loss surgery such as Roux-en-Y gastric bypass or sleeve gastrectomy.
According to researchers at Geisinger Medical Center in Pennsylvania, US, this number increased to 3.3 percent after 10 years and 6.7 percent after 15 years.
The team found that the protective effect against diabetes is greater in gastric bypass patients. On the other hand, about one-third (31.1 percent) of patients without prior metabolic surgery had prediabetes that developed into diabetes within five years, increasing to 51.5 percent and 68.7 percent at 10 and 15 years, respectively.
"This is the first study to analyze the long-term impact of metabolism and bariatric surgery on the potential progression of prediabetes and the impact is significant and durable," said Geisinger's co-author and bariatric surgeon David Parker.
"This shows that metabolic surgery is a prevention as well as a treatment for diabetes."
Prediabetes is a serious condition that occurs when blood sugar levels are higher than normal, but not high enough to be considered type 2 diabetes. Retrospectively, 1,326 patients with prediabetes before undergoing Roux-en-Y gastric bypass or sleeve gastrectomy between 2001 and 2022 were matched with non-surgical controls from a primary care group.
The study was presented at the ongoing American Society for Metabolic and Bariatric Surgery (ASMBS) 2024 Annual Scientific Meeting in San Diego.
