Glucose levels were measured at 30, 60, 90, and 120 minutes after study participants consumed sugary drinks.

According to a study presented at ENDO 2017, a simple oral glucose tolerance test may be an effective way of identifying patients at higher risk for prediabetes who could benefit from early intervention.

Using this common test, researchers from the National Institute of Diabetes and Digestive and Kidney Diseases, Bethesda, MD, collected blood samples prior to, then 30 minutes, 60 minutes, 90 minutes and 120 minutes after individuals consumed a sugary drink, and measured glucose levels at each time point.

Patients were divided into two groups based on how much time passed to reach a maximal sugar level during the test: at 30 minutes or after 30 minutes. Patients who reached a maximal sugar level after 30 minutes were more likely to have prediabetes and reduced pancreatic function. 

Lead author Stephanie T. Chung, MBBS, added, “Our research may help clinicians and public health officials guide patients to better and more cost-effective decisions about risk for prediabetes.”
