1. Risk factors you cannot change include:
- Age. People over 60 have a higher risk.
- Sex and race. Aortic aneurysms are more common in men and among Caucasian (white) people.
- Family history. Your risk for an aortic aneurysm is higher if someone else in your family has had one.
- Using tobacco. Smoking or chewing tobacco is closely connected with aortic aneurysms.
- High blood pressure. The higher your blood pressure, the more stress it places on your arteries. This pressure can lead to an aneurysm.
- High cholesterol. Cholesterol is a soft, waxy substance in your blood that carries fat. If it's too high, it can damage the lining of your arteries.
