The causes of twitching and shaking after drinking should be identified and treated symptomatically. There are several reasons for twitching and shaking after drinking: 1, due to the action of alcohol, because alcohol has an excitatory effect on the nerves, after drinking some patients will have a general twitching and shaking, which is a manifestation of alcohol poisoning. It is possible to send the patient to the hospital for infusion treatment, which can be supplemented with a large amount of glucose as well as vitamin C and vitamin B1, etc., so that the alcohol can be metabolized as soon as possible, which can effectively treat the shivering phenomenon. 2. It may also be a manifestation of seizures, because drinking alcohol can induce epileptic diseases, and if there is a history of epilepsy, it can often induce grand mal seizures. You can inject Valium injections on the spot or send the patient to the hospital for treatment. The main thing to do when having a seizure is to stuff a towel inside the mouth to protect it from biting the tongue. 3. It is also possible that after drinking alcohol, due to improper human defense function, there is a cold and flu and fever leading to convulsions and shivering.
