A member asked:
I sometimes cough so hard i get very lightheaded and feeling like i'm going to faint. is this at all possible?
A doctor has provided 1 answer
Syncope: Yes it is possible. The more vigorous or prolonged continuous cough are the more likely to cause the fainting or lightheadedness. This is due to an exaggerated physiological response to the increase intrathoracic pressure and the effect of the valsalva upon the pulmonary arteries and veins.
