There are two main causes of numbness in the hands after drinking alcohol: the first cause is the accumulation of alcohol on the muscle nerves, resulting in muscle nerve damage. The second reason is that the patient has other underlying systemic diseases that cause changes in the body’s internal environment, which, combined with the stimulation of alcohol, results in peripheral neuropathy. First of all, alcohol has a certain excitatory stimulating effect on muscles and nerves, causing muscles or optic nerves to overreact, resulting in the accumulation of creatinine and lactic acid metabolites, which continuously stimulate muscles and nerves, resulting in the symptoms of limb pain and numbness in hands and feet. In addition, there are other underlying diseases, such as peripheral neuritis from diabetes, where the nerves themselves are already damaged to a certain extent, and the stimulation of alcohol consumption makes the symptoms more obvious. Then in daily life, try to avoid smoking and alcohol, timely physical examination, and timely treatment of physical diseases.
