Dizziness when lying down after drinking alcohol is considered to be the stimulation of the brain or vestibular nerve by alcohol, mostly seen in patients who have drunk too much alcohol, and patients who appear to be dizzy when lying down after drinking alcohol should drink more water appropriately, and can take oral sugar water or oral hypertonic glucose to achieve the effect of osmotic diuresis, so that alcohol is rapidly excreted from the urine. Patients with frequent nausea and vomiting should tilt their heads to the side to avoid misaspiration or suffocation. For patients with obvious dizziness, glucose with naloxone can be given intravenous infusion. If elderly patients become dizzy after drinking alcohol, they should be highly suspected of having acute cerebrovascular disease, such as cerebral infarction and cerebral hemorrhage, and should carefully observe whether the patient has symptoms such as weakness of limbs, distorted eyes and mouth, slurred speech, etc. If the above symptoms are combined, they should call 120 in time to seek medical help.
