Addiction to alcohol in the elderly can cause complications such as alcoholic encephalopathy and alcoholic liver disease, and withdrawal should be gradual. First, the daily amount of alcohol consumption should be gradually reduced and more tea or plain water should be drunk. Secondly, eat more fresh fruits and vegetables and take appropriate protein supplements to ensure daily energy and nutrition. Because excessive consumption can occur during the withdrawal process in older adults, nutrition and energy supplementation are extremely important. Patients may experience withdrawal syndrome during the withdrawal process, including anorexia, nausea, vomiting, tremor, insomnia, anxiety, night sweats, delirium, epileptic seizures, tachycardia and other symptoms, which may cause death in severe cases. Therefore, benzodiazepine sedative and sleeping drugs can be given for symptomatic treatment, including diazepam and lorazepam. Finally, if alcoholic encephalopathy or alcoholic liver disease occurs, symptomatic treatment such as nerve nutrition and liver protection can be given.
