what causes foaming at the mouth when dying
Hello James, how are you?
Hello there, I'm doing well, thank you. How can I help you today?
I'm curious about something a bit morbid, if you wouldn't mind discussing it. I've seen in movies sometimes when people are dying, they foam at the mouth. What causes that?
Sure, it's a quite serious and sensitive topic, but I'll try my best to provide some understanding. Foaming at the mouth when dying can often happen as a result of what's called pulmonary edema. Pulmonary edema is a condition where fluid floods the air sacs in the lungs.
I see, so how does that lead to foaming at the mouth then?
When a person can't expel the lungs' fluid effectively, the fluid can be pushed out and into the airways when breaths are taken. The result is an excess of fluid and air mixing together, which creates a frothy foam. This foam, due to natural reflexes, can then be expelled through the mouth.
