The patient’s dizziness and nausea the day after drinking alcohol is mainly related to the stimulation of the mucous membrane of the gastrointestinal tract by alcohol for the cerebral blood vessels. In this case, it is recommended that patients drink more water or drinks such as honey water or watermelon juice to promote the metabolism of alcohol in the body and slow down these uncomfortable symptoms. Patients are advised to eat some light foods such as millet porridge, which can play a protective role for the gastrointestinal mucosa. However, if the patient’s dizziness and nausea are very heavy, he or she should also consider that the acute cerebrovascular disease has been induced after drinking alcohol and must be treated promptly. If the patient has a history of cerebral arteriosclerosis, cerebral vascular stenosis or hypertension, and has severe dizziness, nausea and unstable walking after drinking alcohol, it is considered that cerebral infarction or transient ischemic attack, cerebral hemorrhage and other diseases may have occurred, so it is necessary to improve the relevant examination in a timely manner to clarify and then carry out symptomatic treatment.
