Diabetic hand numbness may be caused by peripheral neuropathy, which can be relieved by controlling blood glucose and nutrient nerves. 1. Blood sugar control: you can use glucose-lowering drugs such as acarbose, metformin or insulin to control blood sugar under doctor’s guidance. Early and strict control of blood sugar and keeping blood sugar stable is an important way to prevent diabetic neuropathy. 2. Nutritional nerve: commonly used drugs such as α-lipoic acid, methylcobalamin. α-lipoic acid is a strong antioxidant, with inhibition of lipid peroxidation, increase the activity of nerve Na⁺-K⁺-ATPase, anti-inflammatory and other effects; methylcobalamin can promote the function of nerve axon transport and axon regeneration, but also has a good effect of nutritional nerve. There are many reasons for hand numbness in diabetic patients, and it is recommended to go to the hospital in time for regular treatment with the help of doctors.
