(HealthDay News) -- An aneurysm occurs when part of an artery bulges, may rupture, and could cause dangerous internal bleeding.
The National Heart Lung and Blood Institute says risk factors include:
- Being male, since men are more likely than women to have an aneurysm.
- Being age 65 or older.
- Smoking, which can lead to weakening of the artery walls.
- Having a family history or personal history of aneurysm.
- Having high blood pressure, heart disease or another disease that can weaken artery walls.
