Diabetic numbness of hands and feet is mainly related to peripheral neuropathy caused by diabetes, often appearing in the course of diabetes about 5 to 10 years. In addition to numbness of the hands and feet, there may also be pain, burning sensation and some abnormal sensations in both feet, both lower limbs or both hands, and some patients may also experience electric shock-like pain. Diabetic patients due to long-term poor glycemic control, high blood sugar will directly damage the body’s nervous system; or due to long-term high blood sugar leads to fat metabolism disorders, atherosclerosis, etc., causing nerve ischemia and hypoxia, and thus damage. This is one of the most common chronic complications of diabetes. It is recommended that people with diabetes actively control blood glucose, and if there are abnormal manifestations such as numbness of the hands and feet, consult a doctor in time for appropriate diagnosis and treatment.
