What Causes Nosebleeds?


Hey there! Welcome to Life Noggin! If you’ve never had a nosebleed before,
the first one can be terrifying. Especially if you’re young when it happens and have
no idea what’s going on. All you know is that blood is leaking out of your face…for
no reason. But of course, now that you are older you
know that there is a reason your nose started to bleed…you were experiencing a condition
known as epistaxis. When this occurs, it can be one of two types: anterior or posterior.
More than likely, you’ll get an anterior nosebleed which is caused by irritation to
blood vessels in the nasal septum. That’s the part of your nose that separates
your two nostrils. And it’s also the part of your nose that can get deviated, which
can lead to difficulty breathing. And fun fact: it’s estimated that 80% of people
have some type of misalignment to their nasal septum. If I had a nose, I could attest to
that, but sadly my face is pretty featureless. As you can see. But a block can dream! Anyway, in the nasal septum is an area called
the Kiesselbach plexus, where four different arteries come together to form a network of
blood vessels. So, when this area is irritated by either a vigorous blow or a roaming finger,
some of the blood vessels may break. And then you get blood running down your face and possibly
down the back of your throat. But what about dry air? In the northern hemisphere,
winter is coming up and with it comes a lot of nosebleeds. The decreased humidity and
temperature prevent your nose from getting the moisture it needs. This then makes the
mucous membrane more susceptible to bleeding and…Voila! You’ve got blood leaking down
your nostril. The only thing more unappealing than that is saying the words “mucous membrane.” So how do you stop the blood? It’s recommended
that you pinch the soft part of your nose for ten minutes, making sure to keep the nostrils
closed. This pressure helps the blood to clot and stops the bleeding. Oh, and lean forward
during this because otherwise, as I previously mentioned, blood can leak down the back of
your throat. (Which you don’t want.) However, if you are lucky enough to be near a doctor when you get a nosebleed,
if they can easily see the broken blood vessel, they may be able to cauterize, or seal, it
using silver nitrate. So do yourself a favor and keep all fingers
and foreign objects away from your nostrils. Your nose and future self will thank you. Have you ever had a nosebleed? Do you get them often?
