Does anybody else get dark, purplish circles under their eyes when they are low? It may be just a genetic thing, or some other medical problem I have... but I wanted to ask. It's especially noticable after I exercise.
I'm a science nerd and I'm assuming that it has something to do with the hydrostatic pressure that glucose exerts on the blood vessels. Decreased blood glucose concentration equals decreased hydrostatic pressure equals some blood not getting to the capillaries underneath my eyes. Maybe this doesn't make sense, even scientifically, but thought I'd throw it out there.
Anyone else ever noticed this before?
