Passing out when LAUGHING ??

[TICTOC57]

Husband has episodes where if he gets really tickled and laughs, he'll pass out.  Says the Dr. says it a "Vagal Nerve Syndrome".  I've also read where if a Dr. can not find the root cause for something, they tie it back to the VN.  I never saw one of his "episodes" till recently and that's exactly what happened. Get got tickled and passed out.  Fell right out of his chair in a restaurant....but almost as soon as he hit the floor..he seemed to become conscious but looked a bit groggy or lost for a moment...at least while on the floor....Other than that he was OK.

Is this a VN thing or could it be something else?

My friend has a daughter that passes out from laughing and they tell her the same thing.  It is a vagal nerve response.  This has been going on for over 16 years and she is otherwise perfectly healthy.  I wouldn't worry too much

I don't know anyone with it, but of the reading I've done on the vagus nerve and what it can do, passing out due to laughter or stress or anger - those are all on the menu.  I'm no doctor, but the ones that are seem to agree that the only harm comes from any injury that may occur because of a fall.
