Blocked arteries in feet refer to the narrowing or obstruction of blood vessels that supply oxygen and nutrients to the foot, also known as peripheral artery disease (PAD). Causes include smoking, high blood pressure, diabetes, and aging. Symptoms include painful cramping, calf pain, and weakness in the feet. If left untreated, PAD can lead to serious complications such as amputation, stroke, or heart attack. Early diagnosis and treatment with medications, lifestyle changes, and endovascular procedures can prevent these complications. Regular health check-ups and a healthy lifestyle can also help prevent PAD.
