Metformin, a super cheap diabetes drug, is being tested to see if it can actually stop abdominal aortic aneurysms (AAAs) from growing. These are those scary balloon-like bulges in your aorta that can be fatal if they burst. Right now, people with small AAAs just have to wait and hope it doesn’t get worse. If this works, it could mean no more just waiting around—finally, a real treatment could be on the way! #Health #BodyHealth #HealthNews
