Diabetic foot lesions are the result of a complex interaction between many factors, including peripheral neuropathy (including autonomic neuropathy), microangiopathy, macroangiopathy, and poor hygiene. Once it develops, it can face consequences such as amputation due to its complex and difficult treatment. According to incomplete statistics, the proportion of diabetic patients with foot disease in Europe and the United States is about 3% to 10.2%, and about 40% of foot and lower limb amputations in adults are due to diabetic foot disease; in China, the incidence of diabetic foot disease accounts for about 2.6% to 5.2% of diabetic patients, and the amputation (toe) rate is about 14%, and the cost of its treatment is also much higher than that of diabetic patients hospitalized for other reasons during the same period. Diabetic foot lesions are therefore one of the most dreaded and serious complications of diabetes. In order to reduce diabetic foot lesions, diabetic patients must master some of the following basic knowledge of diabetic foot care. 1, choose the right shoes and socks: soft leather shoes, sports shoes is the most ideal shoes. Shoe type is appropriate to choose a square toe, to ensure that the shoe is slightly wider than the foot, breathable and has a certain role in resisting external forces. Do not wear high-heeled, pointed, hard leather and plastic shoes, but also frequently check and remove foreign objects that may exist in the shoes. Socks should be made of cotton and wool, which are both sweat-absorbent and breathable. Don’t wear socks that are too big and don’t wear socks with elastic bands. Change them daily and don’t wear socks with patches or tears to prevent uneven pressure on the feet and affect blood circulation. 2, proper foot washing and foot care: To maintain foot hygiene, it is recommended that diabetic patients wash their feet daily. But before washing feet, be sure to test the water temperature with your hand or thermometer, because most diabetic patients have varying degrees of foot neuropathy, so the ability to feel the temperature is reduced. General requirements with about 40 degrees Celsius warm water, you can soak your feet while adding warm water, and the time to soak your feet should not be too long. After washing the feet to dry the feet with a soft dry towel, and be sure to dry the water between the toe seam, if necessary, a small wind blowing dry with a hair dryer. Autumn and winter feet are prone to dry and cracked, available emollient cream evenly applied to the surface of the foot, sweaty feet can be sprinkled with some talcum powder. Remember not to use hot water bags, electric heaters or direct fire heating after washing your feet in winter to avoid foot burns. 3, adhere to the foot examination and timely treatment to the hospital: you can use their own foot mirror or in the help of others to regularly check the foot, if the skin is dry and cracked, wet and cold, edema, darkening of skin color, lack of sensation, toenail deformation or local redness, pain and heat, etc., may indicate that there has been a foot lesion. It is necessary to go to the hospital as soon as possible. In particular, we must emphasize that you should not use sharp instruments to trim your own feet or use corrosive ointments to avoid foot damage, resulting in irreversible consequences.
