A member asked:

In my sleep the blood from my bloody nose runs down my throat and into my mouth. should i be worried about breathing in blood into my lungs?

A doctor has provided 1 answer

Aspirating blood: Your gag reflex works well even during sleep, so aspirating blood is unlikely. If small amounts do get into the lungs, powerful "clean-up" cells called macrophages break down the blood.
