Peripheral vascular disease is the medical name given to a group of problems that causes poor circulation to the feet and legs. The most common cause of this is artherosclerosis ("hardening of the arteries") in which there is a gradual thickening and hardening of the walls of the arteries (the blood vessels that bring blood to the extremities from the heart). Diabetes is the most common cause of peripheral vascular disease.
Symptoms of poor circulation:
The symptoms that are experienced can depend on which artery is affected and how much the blood flow is reduced. Some of the symptoms include:
- Claudication (this is a dull cramping pain in the calf muscle that comes on after walking a certain distance - it is relieved by rest).
- Numbness or tingling in the foot, or toes can occur.
- Changes in the color of the skin (it becomes more pale, bluish, or reddish).
- Changes in skin temperature (the foot becomes cooler. See cold feet).
- Skin breakdowns, infection and sores do not heal as well as they should.
What causes poor circulation to the foot:
Poor circulation is most commonly caused by a progressive blocking of the arteries in the leg (athersclerosis). Those with diabetes are more likely to develop poor circulation to the foot. Other risk factors for developing poor circulation include a lack of physical activity,smoking, high blood pressure and high cholesterol.
