A member asked:

Sometimes i get lightheaded when i laugh real hard?

A doctor has provided 1 answer

Laugh syncope: I've heard of this before. Laugh- induced syncope or gelastic syncope is usually self limited and results from temporary decreased blood flow to the brain. Breathing reflexes result in strong stimulus to rebreathe. If you have heart problems or other concerns regarding this laugh-induced occurence, please discuss with your md.
