Limb numbness in diabetic patients is usually caused by diabetic peripheral neuropathy, which is the most common and earliest complication of diabetes. In the initial patch clamp examination, it can be found that the nerve conduction speed of sensory and fitness exercises slows down, and numbness is usually symmetrical. It can usually be distributed like gloves or socks, and the legs are usually more serious than the upper arms. First, it will cause numbness and other abnormalities, which may be accompanied by feeling nervous and painful, and it will be missing in the middle and late stages. In addition, in addition to neuropathy, it is necessary to find out whether there are cerebrovascular diseases and spinal diseases, and find the cause and then treat them.

The numbness of limbs caused by diabetes is mainly caused by diabetic peripheral neuropathy. Diabetes is due to the increase of blood sugar, which is likely to cause diabetic capillary lesions. The specific manifestation of diabetic peripheral neuropathy is abnormal symmetry of the distal ends of hands and feet, which can cause numbness, chills and tingling of limbs, or crawling of small ants, even low-paid work and obvious pain. The doctor will make a corresponding appraisal and conduct a detailed examination. If diabetic peripheral neuropathy is diagnosed, the doctor tells you not to smoke or drink. At the same time, we should use various hypoglycemic drugs according to our diet and fitness exercise, and even use insulin glargine to control blood sugar more effectively in some cases.

The complications of diabetes are well known and can be divided into macrocapillary complications and microvascular complications. Macrocapillary complications mainly refer to cardiovascular, cardiovascular and cerebrovascular diseases and complications of lower extremity arteries. Capillary complications include diabetic macular degeneration, diabetic nephritis and diabetic neuropathy, among which diabetic neuropathy can be divided into independent neuropathy and peripheral neuropathy. The prominent manifestations of peripheral neuropathy are paralysis of hands and feet, needle-like pain, glove-sock-like feeling, and in severe cases, sensory nerve skin allergy or sensory nerve loss may occur.

Diabetic patients have numbness of limbs, and most of the reminders are likely to have diabetic peripheral neuropathy. The most common type of diabetic peripheral neuropathy is distal symmetrical sinus neuropathy, and the distal sensory nervous system of hands and feet is more common, usually symmetrical. Typical patients are covered with gloves or socks, and the legs are more serious than the upper arms. Abnormal sensation of limbs may appear first, which may be accompanied by sensory nerve skin allergy and pain. Sensory loss in the middle and late stage may be accompanied by nervous system involvement, leading to sensory ataxia, and most patients may have limb numbness.
