Diabetic foot ulceration is a serious complication of diabetes mellitus, the clinical name of diabetic foot as a diagnostic disease, because once the diabetic foot ulceration is not easy to cure, treatment is also very difficult. The causes of diabetic foot ulcers are the following three: 1. The formation of diabetic foot is mainly due to prolonged diabetes, resulting in atherosclerosis, especially of the arteries of the lower limb vessels, which slows down blood flow and leads to a reduction in blood supply and oxygen supply; 2. Diabetic neuropathy, the perception of pain and heat in the diabetic foot is reduced. Once the foot is injured, such as a needle puncture or being abraded, they do not feel, do not get timely treatment, the occurrence of diabetic foot rupture. After the rupture and then can not get timely treatment, prone to greater ulceration; 3, blood sugar is relatively high, diabetic patients in the case of high blood sugar once there is a small rupture, bacteria are prone to multiply, resulting in the rupture is less likely to be good, leading to further aggravation of foot ulceration. In general, diabetic foot ulcers are mainly due to complications of diabetes, first of all, long time diabetes blood circulation is not good, lower limb blood arteriosclerosis, blood vessels become thin, blood flow becomes slow; secondly, diabetic neuropathy, resulting in weakened nerve perception, the sense of pain, temperature sensation is weakened, can not be timely detection of small rupture; again and poor blood sugar control, rupture mouth can not be timely healing, resulting in rupture The increase of diabetic foot makes it more difficult to cure.
