A doctor has provided 1 answer

Lightheadedness: Presyncope is a state of lightheadedness, muscular weakness, blurred vision, and feeling faint (as opposed to a syncope, which is actually fainting). Presyncope is most often cardiovascular in cause. In many people, lightheadedness is a symptom of orthostatic hypotension. See your physician for a complete evaluation of your symptoms.
