Dizziness is only a clinical manifestation, but there are many causes of dizziness. The common causes of dizziness are: 1. If dizziness is accompanied by weakness, pallor and blackness in front of the eyes, the possibility of anemia should be considered. Common causes of anemia include: peptic ulcer, excessive menstrual flow, hemorrhoids, etc. 2. If you feel dizzy and have insomnia, tinnitus, agitation, memory loss, numbness in the limbs, and cerebral arteriosclerosis that causes cerebral blood vessels to narrow, resulting in decreased blood flow to the brain and insufficient blood and oxygen supply to the brain, this can also cause dizziness. 3. Sometimes high blood pressure can also cause dizziness, but this time it is mostly accompanied by uncomfortable symptoms such as head swelling, panic and irritability. 4. Sometimes cervical spondylosis can also cause dizziness.
