There are many types of diabetic peripheral neuropathy, most commonly distal symmetric polyneuropathy, which causes various sensory abnormalities such as numbness and pain at the end of the limbs of patients, and when the pain is severe patients cannot sleep at night, which greatly affects the quality of life. In the later stage, if there is loss of pain sensation at the end of the limb, the foot breakage will not be easily detected, which can easily lead to a serious diabetic foot. Focal mononeuropathy in diabetic peripheral neuropathy can cause cranial nerve damage, peripheral facial palsy or actinic nerve palsy, etc. Peripheral neuropathy can also develop radiculopathy, causing multiple radiculopathies in the lumbar spine segment, causing weakness and atrophy of the proximal pelvic muscle groups, and affecting lower limb movement. Therefore, it is important to pay full attention to peripheral neuropathy in diabetes and actively control blood sugar to avoid the appearance or progression of peripheral neuropathy.
