Dizziness for several days after drinking alcohol is mainly considered to be related to alcohol stimulation and secondary factors. 1. Alcohol stimulation: dizziness for several days after drinking is mainly related to the fact that alcohol stimulation has not completely subsided. Alcohol contains ethanol, which is metabolized into acetaldehyde after entering the human body, causing irritation to the nerves and blood vessels. 2. Secondary factors: such as the combination of hypertension, cerebrovascular disease and so on. If you suffer from high blood pressure and the blood pressure is not well controlled, it will lead to cerebral vasospasm or dilatation, showing dizziness for several days after drinking. If there is acute cerebrovascular disease, such as acute cerebral infarction, due to ischemia and hypoxia of brain tissue, it will also show the symptoms of dizziness after drinking for several days. If dizziness after drinking for several days is not relieved, it is recommended that the patient go to the hospital in time, under the guidance of the physician to clarify the cause of the disease, and give targeted treatment.
