What is a common risk factor for developing peripheral aneurysms?

Smoking is a well-established risk factor for the development of peripheral aneurysms. The harmful chemicals in tobacco can damage blood vessels, leading to a reduction in the structural integrity of the vessel walls. This damage can promote the formation of aneurysms, which are abnormal bulges that occur when arterial walls weaken. Smoking not only increases the risk of aneurysms but can also exacerbate other vascular diseases and impair overall blood flow, contributing to further complications.

The other options do not contribute to the development of peripheral aneurysms in the same way. For instance, low cholesterol levels are generally associated with a lower risk of cardiovascular diseases. High exercise levels are typically linked to better vascular health, and a healthy diet is important for maintaining healthy blood vessels. These factors are generally protective rather than risk factors for developing aneurysms.
