Scientists say popular Type 2 Diabetes drug has big side effect on the brain in new study

Recent research reveals that metformin, a long-used diabetes drug, may function through the brain more than previously believed. Scientists found out that the medication reaches the ventromedial hypothalamus, where it turns off a protein named Rap1 that impacts glucose regulation. Although it has been widely used for more than 60 years, its complete actions remain unclear. Researchers believe these findings may result in fresh treatments for diabetes and additional metabolic or neurological conditions.
