Although both hypertensive and hypotensive dizziness show dizziness, the difference between dizziness is mainly manifested in the different causes and accompanying symptoms. 1. Causes: Dizziness in hypertension is caused by elevated blood pressure, resulting in increased cerebral perfusion. Hypotensive dizziness is caused by lower-than-normal blood pressure and insufficient cerebral perfusion; the main difference between the two is the difference in blood pressure, which can be recognized by measuring blood pressure. 2. Accompanying Symptoms: In addition to dizziness, hypertension is accompanied by neck pain, occipital or temporal throbbing sensation, and in serious cases, complications of the heart, brain, kidneys and other organs may also occur. Low blood pressure dizziness is accompanied by symptoms such as coldness, pallor, and weak pulse. If dizziness is severe or there are other symptoms, it is recommended to go to the hospital in time.
