For patients with normal blood pressure but dizziness, the following points should be considered: First, cerebrovascular disease should be considered first. In cases of transient ischemic attack, acute cerebrovascular insufficiency of blood supply, or cerebral embolism or cerebral infarction, the blood pressure will be normal but with dizziness or even headache. Second, other factors that cause neurovascular headache, such as acute neurological tinnitus, or otoliths, Meniere’s syndrome, can also lead to normal blood pressure but dizziness. Third, for endocrine diseases, often in thyroid dysfunction and adrenal dysfunction, there are symptoms of dizziness. For patients with previous diabetes, if there is a significant hypoglycemic coma, diabetic ketoacidosis, or hyperosmolar coma, the blood pressure will be normal but the patient will experience dizziness. Fourth, in patients with chronic cardiac insufficiency or malignant arrhythmias, this clinical manifestation will also be present.
