Alcohol is neurotoxic to the nerves and can cause dizziness and discomfort. Alcohol is metabolized by the liver, which can increase the burden on the liver and impair liver function. Alcohol can also directly stimulate the stomach mucosa, which can cause vomiting symptoms. If you feel dizzy and nauseous after drinking, the most direct way is to go to the bathroom and use chopsticks, spoons and other pressure on the root of the tongue to spit out the excess alcohol to reduce the further absorption of alcohol and reduce the symptoms of intoxication, and then drink water to promote metabolism. If the intoxicated person is already unconscious, let him sleep on his side with his head bent to the side to avoid accidental inhalation of flat vomit and suffocation. If the patient is still unconscious, unresponsive to calls, wrong breathing rate, blue face, purple lips, and cold limbs, there may be serious complications, and it is necessary to call 120 and rush to the hospital for resuscitation.
