In my brief survey and statistics of hospitalized patients, I found that more than half of the patients with diabetic foot had either mild or severe peripheral neuropathy. Why is neuropathy one of the main causes of diabetic foot? It is because it has the following characteristics: First, having peripheral neuropathy causes the pain sensation to diminish or even disappear. What does that mean? Let’s say you stabbed something on your foot and cut it, you don’t feel pain, you can’t find the wound, and often when you find it, there is already an infection. Second, it can cause temperature sensation to decrease or even disappear. Especially elderly patients, various reasons often cause lower limb pain, numbness, weakness, etc., we would like to relieve relief by bubble feet to relieve. For example, you use particularly hot water to wash your feet soak, soak your feet when you will not feel how high the temperature, or even already quite high, you still can not feel, so easy to burn. There are also hot water bags, hand warmers, etc., can burn the feet caused by diabetic foot. Third, peripheral neuropathy can also cause abnormal sensation of the peripheral circulation of the hands and feet, sometimes some scratching, pain, burning sensation ants, etc., will unconsciously, to scratch with their hands, easy to scratch, will also cause wounds, the formation of sugar feet. Fourth, there are some patients with neuropathy is caused by vascular disease, the formation of wounds, wounds due to the lack of adequate blood, drugs and nutrient supply, will not heal for a long time, and eventually the infection will develop into a diabetic foot. Therefore, diabetic peripheral neuropathy is quite dangerous and implies a great potential risk. However, in one case, diabetic peripheral neuropathy is not easily distinguished from symptoms caused by other problems, making it difficult to diagnose, and most of them are only discovered when a diabetic foot ulcer develops. Therefore, it is necessary for everyone to have regular checkups and screenings. It is generally recommended that patients with advanced age, long disease duration, and large blood sugar fluctuations should be screened every six months, while other patients can be screened once a year. Once peripheral neuropathy is detected, it is important to receive treatment under the guidance of a professional doctor to avoid avoid avoidable damage to patients due to non-treatment or improper treatment methods.
