Peripheral artery disease (PAD) is a condition that affects the circulatory system, reducing blood flow to the lower extremities. While there is no singular cause of PAD, atherosclerosis is an incredibly common and significant factor in patients with this ailment. For those unfamiliar with atherosclerosis, this condition is caused by the widespread accumulation of fatty deposits in the arteries. Making necessary lifestyle changes such as quitting tobacco, exercising daily, and eating a well-balanced diet can help treat PAD.
