Many friends ask me this. The sky spins when they get dizzy, they even get nauseous and vomit, and their hearts are filled with a sense of dread. I tell them that everyone will experience dizziness at least once in their life. In fact, I have had many episodes of dizziness myself. Dizziness is one of the most common clinical manifestations in neurology, and the most common causes are inadequate blood supply to the posterior circulation, cerebral arteriosclerosis, cervical spondylosis, cerebral infarction, otoliths, and bitemporal auditory neuritis. If middle-aged or elderly people, who have hypertension, diabetes and other underlying diseases, suddenly experience persistent dizziness that cannot be relieved, they must be alert! It is likely to have a stroke! You should seek medical attention as soon as possible! There are also some benign dizziness, many are caused by fatigue, poor rest, and adolescent dizziness, etc. The treatment is different, and I will share it with you later when I have time.
