The study showed that only 1.8 per cent of patients progressed to diabetes in five years after weight loss surgeries like Roux-en-Y gastric bypass or sleeve gastrectomy.
The numbers rose to 3.3 per cent in 10 years and 6.7 per cent after 15 years, according to researchers from the Geisinger Medical Center in Pennsylvania, US.
The team found that the protective effect against diabetes is higher among gastric bypass patients. On the other hand, nearly a third (31.1 per cent) of patients with no prior metabolic surgery saw their prediabetes develop into diabetes within five years, which increased to 51.5 per cent and 68.7 per cent at 10 and 15 years, respectively.
