What Factors Causes Diabetic Foot?

Diabetic foot is a common complication of Diabetes which has a highest incidence among complications of Diabetes. Then, what factors can cause diabetic foot? Here are some conditions which can lead to diabetic foot as follows:

One, diabetic neuropathy is an important factor which causes diabetic foot. 60 to 70 percent of patients suffer from diabetic neuropathy, which makes hypoaesthesia or sensation's lose. As a result, foot can not properly react and adjust to negative factors such as tight socks, excess small shoes and too hot foot-washing water, etc. Besides, autonomic neuropathy leads to the abnormal function of skin such as sweating or thermoregulation, which causes dry skin, chap and skin split. In addition, it provides entry for infection. Further more, neuropathy of motor nerve can cause transformation of metatarsal bones and toe, which increases the pressure of pelma and causes foot muscle atrophy. When plantar fat pad begins to ectopia, buffering capacity of partial pelma will be reduced and the pressure will increase, which causes interphalangeal arthrogryposis and transformation.
Consequently, it increases pressure inside shoes, which leads to foot ulcer.

Two, diabetic microangiopathy: embolism can cause foot ulcer and gangrene. Patients with Diabetes have a high incidence of peripheral artery atherosclerosis. The conditions of thrombus, medium and small atherosclerosis of legs,microvascular thickened basement membrane, luminal stenosis and micro-circulatory disturbance, can cause dystrophia of skin and nerve and aggravate damage to neural function. Besides, ischemia causes foot with ulcer difficult to recover due to its shortage of oxygen and nutriment.

Three, infection: the dysfunction of white blood cell causes the body's easily being infected, and the infection can aggravate the metabolic disorder. Consequently, it causes blood sugar increases and ketosis will further damages patients' immunity function. As a result once they catch an infection of foot, it will be quite difficult to control or correct it. For example, patients may suffer partial infection of foot or even amputation just because of blister on foot.


For patients with diabetes, the wound is difficult to heal, they should pay more attention to effectively protecting any would in particular of their diabetic foot. So they can take a series of measures to protect their foot from damage and live a good life.
