The man who had a seizure without drinking – a case of alcohol withdrawal. When I went to a restaurant at noon, I saw a man lying on the floor, foaming at the mouth, not responding to calls, with twitching limbs and a stiff body, typical of a grand mal seizure. The family was at a loss for words and the other customers were nervous. Based on my experience, I felt that the patient might be alcohol-dependent, and asked the family if this was true. The patient had been drinking alcohol daily for more than 10 years, drinking half a kilogram to one kilogram of white wine every day. In addition to sleeping, he drank constantly and hardly took any meals, and his body lost weight. Because of indulging in drinking, he could not do his work. Under the persuasion of his family, he tried to quit drinking on his own, a total of three times. Every time he stopped drinking, he would have a seizure within a day or two, the same as what I saw. He was afraid to quit drinking on his own and came to our hospital accompanied by his family to quit drinking. He didn’t drink that day and registered for the afternoon, but he didn’t expect to have an attack at noon. This is a more serious, and risky, alcohol withdrawal symptom. After abruptly stopping or significantly reducing the amount of alcohol, the withdrawal symptoms may also have other manifestations, including sweating, rapid heart rate, hand tremors, insomnia, nausea, vomiting, hallucinations, and excitement and agitation. Reminder: After becoming dependent on alcohol, you need to stop drinking under the guidance of a specialist and not on your own, otherwise it may be dangerous.
