According to the World Health Organization (WHO), the diabetic foot is an infection, ulcer or deep tissue destruction of the foot associated with local nerve abnormalities and peripheral vascular disease in the distal lower extremities. As one of the most disabling complications of diabetes. According to the International Diabetic Foot Working Group meeting, the incidence of diabetic foot accounts for about 15% of diabetic patients, and about 40% of them require amputation. The early symptoms of diabetic foot are obvious, and patients can avoid deterioration by actively self-examining their condition. For example, if you walk a little far away, you will feel pain in your calves and feet, but the symptoms will disappear on their own after a short rest, and then the pain will appear again when you walk again. Usually, there are also cold feet and slow response to cold, hot and painful stimuli. Once there is damage to the skin of the foot and the wound is difficult to heal, etc., once these symptoms are present, the patient should determine whether he has a diabetic foot. The “Nei Jing” cloud: “the upper work to cure the disease, the middle work to cure the disease, the lower work to cure the disease”, the treatment of diabetic foot disease focuses on prevention, to avoid amputation. The specific measures are as follows: 1, strict control of blood sugar and diligent inspection The pathophysiological basis of diabetic foot is due to the long-term impact of hyperglycemia, lower limb vascular and neuropathy, resulting in insufficient blood supply to the lower limbs, nerve sensation, reduced sensation to pain, prone to foot injury, infection, ischemia and necrosis. 2, foot warming temperature is the key Diabetic patients are more likely to feel numb feet, feet cold than normal people. Therefore, many people choose electric blankets, hot water bags and other methods to warm up. However, because the protective reflexes of the feet of diabetic patients are weakened, the response to heat sensation is dull, some people in the case of “unaware” feet burned. Diabetic patients, winter warmth need to prevent baking, hot. It is best to take a warm water footbath and foot massage before going to bed, and if necessary, you can use ginger or other herbs to invigorate blood stasis and boil water to soak your feet. When diabetic patients soak their feet, the water temperature should not be too high, to 37 ℃ is appropriate. Time should not be too long, to 15-20 minutes is appropriate. Appropriate emollient cream can be used to prevent dry and cracked feet. 3, choose the foot comfortable shoes and socks Diabetic patients should wear shoes and socks to fit the foot comfortably, should not be too loose and too tight. Because of the role of gravity, lower limb venous reflux than the upper limb of the trunk resistance, if the shoes and socks are too loose can lead to an increase in the local venous valve load, affecting the venous return flow and speed; but the shoes and socks are too tight compression of the blood vessels, resulting in increased resistance to blood flow, the arterial and venous blood flow are not conducive to both the blood supply and the excretion of metabolites. Diabetic patients need to prepare shoes with wide toes, appropriate size, good breathability and not crowded feet.
