Alcohol can directly stimulate brain tissues and cause symptoms such as dizziness, body rotation, feeling unstable walking, nausea, vomiting, headache, etc. Patients with the above symptoms after drinking alcohol are advised to drink more water and also drink sugary drinks such as fruit juice to promote alcohol excretion. For patients with obvious dizziness, intramuscular or intravenous naloxone can be injected, which can relieve the symptoms of alcohol poisoning as soon as possible. If the patient is in a drowsy state or accompanied by nausea or vomiting, drinking water is not recommended to avoid vomiting, choking, and accidental aspiration. Drinking alcohol can also induce acute cerebrovascular disease, especially in elderly patients with symptoms such as dizziness, weakness of limbs, sensory impairment, distorted mouth and eyes, and difficulty in swallowing after drinking alcohol should be highly suspected to be combined with acute cerebrovascular disease, and patients are advised to go to the hospital as soon as possible, and if necessary, head CT or head MRI can be examined.
