One less well known ailment is a condition known as peripheral vascular disease (or poor circulation). This occurs when there is a problem with the circulation in the arms and legs. More often than not, the legs are much more commonly affected. The most common cause of peripheral vascular disease is atherosclerosis or a hardening of the arteries. There are many risk factors for this such as a lack of exercise, too much cholesterol in the diet, have other conditions such as diabetes and a poor family history of the condition. If the condition exists the legs are often cold due to the lack of blood flow, there will be no pulses felt and the skin often becomes fragile. The biggest problem with poor circulation in the lower limb is that any time a cut or sore develops, there may not enough nutrients available for the healing to take place and fight any infection from developing. This can have potentially very serious consequences for those with this condition.
