The diabetic foot is one of the serious complications of diabetic peripheral vascular neuropathy and an important cause of disability, death and incapacity in diabetic patients. Amputation due to diabetic foot greatly affects patients’ own quality of life and life expectancy, and also causes heavy burden to families and society. In recent years, the incidence of diabetes has been increasing year by year, and the incidence of diabetic foot has also been increasing. In order to reduce the occurrence of diabetic foot, prevention should be the main focus, timely detection, early diagnosis and early treatment. The following are some suggestions to prevent diabetic foot: (1) adhere to the daily foot soak with warm water, the temperature of 35 to 40 degrees Celsius, and appropriate massage with both feet rubbing each other to promote blood circulation on the soles of the feet. (2) Wash and dry your feet and then carefully trim your toenails with scissors and smooth the edges. (3) feet with corns, calluses or Youzi, do not deal with their own, must go to the hospital to find a doctor to deal with. (4) Do not play barefoot to prevent stabbing by foreign objects on the ground. (5) Choose cotton socks as much as possible, and do not tighten the edges of the socks too much to avoid strangulation marks on the socks. (6) In cold weather, do not use hot water bags or hot water bottles to warm your feet to prevent burns. Use thick socks and blankets to keep warm. (7) Avoid wearing small shoes, hard-soled shoes and high-heeled shoes to prevent foot movement from being restricted, and for sports, wear sports shoes. (8) Maintain hygiene in shoes, wash soles and socks regularly. (9) Keep the inside of shoes dry and actively prevent foot odor. (10) For dry skin, lubricants or skin care ointments should be used, but not between the toes. (11) Absolutely no chemicals or creams should be used to remove keratinized tissue or calluses Diabetics need to pay special attention to soaking their feet in hot water. Specific measures are as follows: 1. Poor blood supply to the feet, diabetic patients often feel cold feet, wrapped in quilts are useless, like to warm the feet with hot water bags, hot water to scald the feet. Before going to bed at night, a pot of hot water scalding feet does have the effect of relieving fatigue, and also has a certain health effect, but diabetic patients should be particularly cautious. 2, diabetic patients because of peripheral neuropathy resulting in reduced skin sensory function of the foot, can not accurately determine the level of water temperature, the foot does not know tend to avoid harm, even if soaked in very hot water often do not feel. Severe patients do not know when they are scalded, making the scald further aggravated. 3, because when normal people’s skin encounter hotter hot water, the local blood vessels will expand, blood flow will accelerate, so that the blood will take away the excess heat, so that the local does not suffer, and diabetic patients this function will be greatly reduced. Diabetic foot microcirculation disorders and vascular lesions make the skin blood vessels cannot expand normally, and the reduction of blood supply also makes the skin not have enough blood to take away the heat, so that the heat will gather in the local area and scald easily. And once the scald occurs, it often evolves into necrosis because the foot tissue becomes less nutritious and has a lower recovery capacity.
