Low blood pressure, defined as a blood pressure reading below 90/60 mmHg, can easily cause dizziness. It may lead to cerebral vascular spasm and could also contribute to atherosclerosis, thus causing dizziness in patients. In addition to dizziness, low blood pressure can also result in symptoms such as nausea, physical fatigue, pale complexion, and blurred vision.
