Peripheral artery disease, or PAD, affects the blood vessels that carry blood to the legs and feet. It develops when arteries in the legs become narrowed, reducing the amount of blood that reaches nearby tissues. A common cause is atherosclerosis, which occurs when fatty material called plaque builds up along artery walls. Reduced circulation means the muscles may not receive enough blood and oxygen during activity. As PAD becomes more severe, circulation can remain limited even while a person is resting. Diabetes, high blood pressure, and high cholesterol can increase the risk of developing PAD.
Poor circulation from PAD can cause noticeable symptoms in the lower legs and feet. Pain, aching, or burning may occur during walking or exercise and improve after several minutes of rest. Some people develop numbness in the legs or feet while resting. The affected foot may also feel cool or appear pale. As the condition progresses, pain may begin with less activity and eventually occur at rest. Severe PAD can cause slow-healing sores on the feet or toes. Skin discoloration and changes in the toenails may also develop. These symptoms are important because reduced circulation can make it harder for damaged tissues to heal properly.
A podiatrist can examine the feet for signs that may be associated with poor circulation and determine when further medical evaluation is necessary. An examination may reveal a weak pulse, skin changes, or slow-healing sores. PAD can be evaluated with tests that compare blood pressure in the arms and legs or examine blood flow through the arteries. Because severe PAD can lead to serious complications, changes such as new foot sores should not be ignored. A foot that suddenly becomes cool, pale, or numb also requires medical attention. If poor circulation is causing persistent foot pain or noticeable changes in your feet, it is suggested that you consult a podiatrist for an evaluation and appropriate care options.
Poor circulation is a serious condition and needs immediate medical attention. If you have any concerns with poor circulation in your feet contact John Jachimiak, DPM of Boulder County Foot & Ankle. our doctor will treat your foot and ankle needs.
Poor Circulation in the Feet
Poor blood circulation in the feet and legs is can be caused by peripheral artery disease (PAD), which is the result of a buildup of plaque in the arteries.
Plaque buildup or atherosclerosis results from excess calcium and cholesterol in the bloodstream. This can restrict the amount of blood which can flow through the arteries. Poor blood circulation in the feet and legs are sometimes caused by inflammation in the blood vessels, known as vasculitis.
Causes
Lack of oxygen and oxygen from poor blood circulation restricts muscle growth and development. It can also cause:
- Muscle pain, stiffness, or weakness
- Numbness or cramping in the legs
- Skin discoloration
- Slower nail & hair growth
- Erectile dysfunction
Those who have diabetes or smoke are at greatest risk for poor circulation, as are those who are over 50. If you have poor circulation in the feet and legs it may be caused by PAD and is important to make changes to your lifestyle in order to reduce risk of getting a heart attack or stroke. Exercise and maintaining a healthy lifestyle will dramatically improve conditions.
As always, see a podiatrist as he or she will assist in finding a regimen that suits you. A podiatrist can also prescribe you any needed medication.
