Abdominal aortic aneurysm: Is exercise safe?

Exercise is safe for most people with abdominal aortic aneurysms — with a few caveats. You should avoid exercise that involves lifting more than 50 pounds and prolonged squatting. This combination is particularly dangerous because it can cause a temporary yet significant increase in blood pressure that could rupture the aneurysm.

People with small- to medium-sized abdominal aortic aneurysms — up to 5.5 centimeters — who aren't candidates for surgery may participate in moderate exercise, such as walking or riding a bike. However, check with your doctor for specific recommendations based on your overall health and specific circumstances.

People with large abdominal aortic aneurysms — more than 5.5 centimeters — should avoid even mild exercise, unless otherwise directed by their doctors.
