Aortic aneurysms are most common in men older than 60, but they can happen in women as well. The biggest risk factors are a family history of aortic aneurysms and a history of smoking. Other risk factors include:
Atherosclerosis, such as heart disease or peripheral arterial disease.
Chronic obstructive pulmonary disease (COPD) or emphysema.
High blood pressure.
High cholesterol.
To lower your risk, your doctor might suggest lifestyle changes that include quitting smoking, eating a heart-healthy diet, and getting regular exercise. Your doctor may also put you on medicine to lower your blood pressure and cholesterol.
