Stage 4 peripheral artery disease (PAD) is a serious condition in which arteries in the legs become narrowed or blocked due to a buildup of plaque. This buildup of plaque causes reduced blood flow to the legs and can lead to pain, numbness, and muscle weakness. It can also increase the risk of amputation, heart attack, and stroke.
Symptoms Of Stage 4 PAD
The most common symptom of stage 4 peripheral artery disease is pain in the legs, usually in the calf muscles. This pain is often worse when walking or exercising and can be relieved with rest. Other symptoms include numbness, weak or heavy feeling in the legs, and slow-healing sores or ulcers.
Risk Factors and Causes of PAD
The most common cause of PAD is atherosclerosis, which is the buildup of fatty deposits in the arteries. Other risk factors include smoking, diabetes, high cholesterol, high blood pressure, obesity, and a sedentary lifestyle.
Diagnosis and Treatment of Stage 4 PAD
A doctor will typically diagnose stage 4 peripheral artery disease using a physical exam, blood tests, and imaging tests such as an ultrasound. Treatment for PAD usually includes lifestyle changes, such as quitting smoking, exercising more, eating a healthy diet, and controlling blood sugar and cholesterol levels. Medications such as antiplatelet drugs, anticoagulants, and statins may be prescribed to reduce the risk of blood clots and improve blood flow. In some cases, surgery may be necessary to remove plaque or widen the arteries.
