Diabetic foot is a foot lesion caused by narrowing and occlusion of microvessels and large, medium and small blood vessels and blood flow disorders due to long-term poor control of blood glucose in patients, which leads to ischemia of nerve cells in the foot, followed by damage to sensory, motor and vegetative nerves. The clinical manifestations are coldness, numbness, pain, intermittent claudication or/and with infection in the foot. Daily care of diabetic foot should pay attention to the following points: People often say “flat foot”, that is, the arch of the foot disappears, may be related to diabetes. Mallet fingers (toes like small drumsticks), dry feet, calluses (commonly known as foot pads), etc. are also more prevalent in diabetic patients. In clinical practice, doctors cannot only look at patients with or without ulcers, but also alert patients with dry feet, cleft, flat feet and other manifestations to avoid deeper damage to foot function. 1, the learning of wearing shoes and socks Diabetic patients usually wear shoes, pay attention to see whether the shoes are flat inside, the insole has no wrinkles. When walking, learn to walk smoothly. Diabetics should usually wear appropriate shoes and socks, and the soles of shoes and socks should be kept flat. When buying shoes, go in the afternoon instead of choosing the morning, because our feet are more distended in the afternoon, and the shoes bought at this time may be more suitable for sugar lovers. Try to wear soft cloth-soled shoes, and add insoles to wear leather shoes. Wear socks with good breathability, especially for patients with sweaty feet, change 2~3 pairs of socks every day, always keep them dry and don’t get them wet. Because once the socks are soaked, they are easy to pleat, leading to rubbing the skin, thus forming calluses and so on. 2.Cautiously treat all kinds of symptoms People often say “flat feet”, that is, the arch of the foot disappears, may be related to diabetes. Mallet fingers (toes like small drumsticks), dry feet, calluses (commonly known as foot pads), etc., are also more prevalent in diabetic patients. In clinical practice, doctors should not only look for the presence or absence of ulcers, but also alert patients with manifestations such as dry feet, cleft and flat feet to avoid deeper damage to foot function. Patients should pay full attention to the presence of corns, calluses, edema, and deformities in the foot. This is because gangrene is often triggered by these problems. These symptoms are caused by shoes that are too small, uneven soles, and wrinkled socks, which lead to repeated friction on the foot, which in turn leads to damage. Patients with these symptoms must do proper treatment, do not ignore them, and do not just pick them with a needle or cut them with scissors, as this is very likely to cause infection and increase the size of the breakout. After the occurrence of callus and corns, the pressure on the local tissues can increase by 30%, so it should be trimmed and pacified in time. It is recommended that patients choose a regular hospital, or a foot care facility that specializes in these issues. 3, foot soak water temperature should be appropriate with warm water (or Chinese medicine) foot soak can play a role in improving blood circulation in the foot, the prevention of terminal ischemia, the formation of gangrene is beneficial. However, the water temperature should be appropriate when soaking feet, should not be too high. Because with the development of nerve damage, the peripheral nerves of diabetic patients can not sense the external temperature normally, even if the water temperature is very high, they can not feel it and can easily be scalded, which can lead to very serious consequences. And the water temperature is too low, and can not play the role of blood activation. Therefore, try the water temperature with your hands before soaking your feet.
