what causes peripheral artery disease

Peripheral artery disease (PAD) is mainly caused by atherosclerosis, a process where fatty deposits called plaques build up in the arteries, narrowing and hardening them. As your dad’s doctor mentioned, the narrowed arteries reduce blood flow, primarily affecting the legs, leading to the pain and cramps he’s experiencing, known as claudication. There are several risk factors for PAD, and some that you mentioned already apply to your dad. High blood pressure and high cholesterol contribute significantly to atherosclerosis, and a history of smoking can linger as a risk factor, even if he has since quit. Age is another factor; PAD is more common after 60, aligning with when he began experiencing symptoms. While diabetes isn’t a concern for your family, it’s worth noting that it can greatly increase the risk of PAD due to its impacts on blood vessels. Lifestyle changes can indeed help manage PAD and slow its progression. Encouraging your dad to follow a heart-healthy diet low in saturated fats, trans fats, and cholesterol could be beneficial in controlling blood pressure and cholesterol levels. A diet rich in fruits, vegetables, whole grains, and lean proteins is often recommended. Regular, moderate exercise, like walking, is essential, even if it initially causes discomfort. He may need to start with shorter distances and work up as tolerated; walking programs under supervision can be particularly helpful. Apart from lifestyle changes, it is important for your dad to work closely with his healthcare provider on managing risk factors with medications if needed, like those for blood pressure and cholesterol. Sometimes, depending on severity, more active treatments like angioplasty or surgery to open up narrowed arteries might be considered, but this would depend on individual clinical assessment. While it can be concerning, with proper management and adjustments, many people with PAD live full, active lives. It is always good practice to keep close communication with healthcare professionals to monitor and guide his management strategy.
