Why green?

[bigemet]

Hi guyz


What's the biology behind looking greenish or pale when someone's nauseous? I've seen some ppl looking fine with color in their face right b4 throwing up. But some people look so green and yellowish or just realy white...

i have mostly seen tha nice pasty pale look. I am not sure though.


one time...my husband had alot of blood taken from him for some tests....and man...i thought "green around the gills" was just an expression...he was green!!!

I think it happens to some people who have yellow based skin, and when the blood leaves the surface, the skin appears greenish. I am just guessing.

It's a shift in blood levels of carbon dioxide and red blood cells starving for oxygen because of that. It's caused by not breathing adequetly while you are nauseous.

My friend with a masters degree in biology told me that!
