Dizziness can occur even with normal blood pressure, as it can occur not only with hypertension, but also with other diseases. Other diseases that commonly cause dizziness include infections, febrile diseases, and dizziness can also occur in patients with cerebral atherosclerosis, craniocerebral trauma syndrome, and cardiac neurosis. Other diseases outside the circulatory system, including anemia, drug intoxication, and uremia, can also cause dizziness. Dizziness is a self-induced sensation of spinning and swaying when the patient’s sense of balance or spatial orientation is impaired, and may be a precursor to serious illness or a functional disease. Systematic treatment is recommended to identify the cause of dizziness and to provide systematic treatment.
