Diabetes is more than just high blood sugar. About 60% to 70% of diabetic patients will develop peripheral neuropathy. Peripheral nerves are the nerve tissues in the body other than the brain and spinal cord, and are responsible for various sensory and motor activities in the body, as well as innervating the internal organs of the body. When peripheral nerves are damaged, many functions in the body will be affected and a variety of symptoms will occur. Doctors explain that numbness in the feet is a typical symptom of diabetic peripheral neuropathy in its early stages. There are several characteristics: 1. Nerve compression in some areas can lead to numbness and tingling in these areas, and can even make the patient prone to falls and fractures. Due to the numbness, patients are not sensitive to temperature and pain, and sometimes they may suffer from burns, cuts, or choking without realizing it, and may develop diabetic foot. Early diagnosis and treatment is the key 1, if there is no cause but the patient has numbness in the feet, pay attention to check the blood sugar level, fasting blood sugar greater than or equal to 7.0mmol/L, or two hours after the meal blood sugar greater than or equal to 11.1mmol/L can be diagnosed as diabetes. 2, once diagnosed with diabetes, patients must strictly control blood sugar. The patient should eat more vegetables and less meat, do more daily exercises, maintain an optimistic mood, and actively control sugar. In addition, patients with diabetes must undergo regular screening and evaluation of their condition. Check peripheral neuropathy at least once a year after the diagnosis of diabetes to strengthen the importance of their health status. 3. If patients have neuropathy, they should seek medical attention in a timely manner, follow medical advice and use medication, and check their feet daily for damage, strengthen foot care, and deal with dry, cracked feet, corns, and mold infections as soon as possible.
