Can epistaxis or nosebleeds be a of cause death?
Yes, it can, but it is extremely rare.
The main issue is that epistaxis can be a sign of potentially fatal diseases:
Here are some causes which can lead to fatal complications if left untreated :
Death by massive hemorrhage can occur when epistaxis is the result of a ruptured aneurysm [4, 5, 6]:
Any injury, that results in external bleeding can lead to death, since it is a breach in the body's defenses and an entry point for pathogens.
When you have nose bleeding the blood must be coming from somewhere. Usually from inside your body.
That means there is a hole in your body which is big enough for blood to stream out.
That in return also means that through the same hole things can get back inside your body.
For example any kind of virus or bacteria.
That does not mean every bleeding is potentially lethal. But depending on the environment the body is in the chance of infection is certainly greater with a lesion (hole in the circulatory system) than without it.
Yes. Usually only in the case of someone with hemophilia (no blood clotting) but it could theoretically occur with any serious uncontrolled nosebleed. Since blood in the stomach tends to cause vomiting, you could also lead to a scenario where someone who was uncomfortable with blood would pass out due to being scared of the blood and then aspirate (puke and then breath in) and end up dying in that way.
Hasn't happened to me though.
Yes it can but it is very rare.
Most often when you get a nosebleed it is either a vein or capillary that ruptures. However in some cases it is arterial bleeding which is always an emergency.
I have honestly noticed when I have nosebleeds often each one is worse than the previous with some having a lot of bleeding but still no gushing from an artery.
Arterial rupture in the nose and hemophilia are the 2 most common blood related causes of death from a nosebleed.
Another possibility is that it took too long for the broken nose to be treated and the cartilage ruptured an artery during the fracture. However this is much rarer than arterial rupture that is not related to fractures.
