Dizziness and nausea after drinking coffee may be related to the sympathetic excitation caused by taking coffee, and the main treatment methods are to pay attention to rest, maintain mood relaxation, appropriate drinking water and timely consultation. Attention to rest and relaxation can avoid further sympathetic excitation due to emotional excitement and avoid aggravation of symptoms. Drinking water and urinating more often can promote the excretion of caffeine, which can help relieve dizziness and nausea. For those who can not be relieved, it is necessary to go to the hospital in time to avoid accidents, and can follow the doctor’s instructions to take drugs to regulate the function of the sympathetic nerves, such as metoprolol, propranolol and so on. Due to the individual differences in clinical manifestations, the specific situation requires a doctor’s consultation.
