Dizziness and vomiting after drinking alcohol are caused by the stimulating effect of alcohol on the stomach and cerebral cortex. As each person’s constitution is different, there are also differences in tolerance. Alcohol entering the stomach causes the stomach muscles to contract violently, and food is ejected from the small intestine and causes vomiting. The oxidation of alcohol in the body produces the chemical acetaldehyde, which can cause deep irritation in the body, leading to dizziness and vomiting. Wine in the brewing process will contain traces of miscellaneous alcohol oils, such substances can also lead to vomiting after drinking. After drinking, you can drink plain water to dilute the alcohol and ease the burden on the liver, or you can drink alcoholic soup, such as fish soup with shredded ginger. Fruits and desserts contain a large amount of fructose, which can accelerate the oxidation of ethanol to ease the feeling of vomiting. But should not drink strong tea, tea contains theophylline, which can cause blood pressure to rise due to vasoconstriction.
