”Diabetic foot” is a serious complication of diabetes mellitus, which is a major cause of amputation. It is mostly seen in patients with poor long-term glycemic control and is caused by diabetic neuropathy and peripheral vascular disease. The typical clinical manifestation is: abnormal sensation at the beginning (such as numbness of the foot) → intermittent claudication → resting pain → diabetic foot. How can we avoid the danger of “foot loss”? 1.Strict control of blood sugar Control fasting and postprandial blood sugar within the standard range, which is the basis of diabetes treatment. 2.Control lipid and blood pressure Most of the diabetic patients have disorders of lipid metabolism, and the increase of blood lipid leads to the formation and proliferation of atherosclerotic plaque in arteries, which is the main cause of atherosclerosis, narrowing of blood vessels and occlusion. Therefore, lipid-regulating drugs such as atorvastatin and resulvastatin must be added. Also treat the presence of hypertension. 3, choose the right shoes and socks, the water temperature should be appropriate when washing feet Loose, soft, thick-soled cloth shoes and cotton socks can reduce the chances of foot injury. The temperature of the water used for foot washing should not exceed 40 degrees. 4, pay special attention to the care of the toes Trimming toenails must be careful to prevent cutting toenails and skin. 5, timely and correct treatment of skin breakage Diabetic patients once the foot skin breakage or infection, should immediately go to a regular hospital to find a specialist to deal with. 6, other measures diabetic patients should maintain appropriate exercise, weight control, quit smoking, etc..
