Nosebleeds aren’t usually a sign of anything serious. They’re common, particularly in children, and most can be easily treated at home.
See a GP if:
- you have regular nosebleeds
- it feels like your heart isn’t beating normally or you’re breathless
- you’re taking a blood-thinning medicine, such as warfarin
- you have a condition that means your blood can’t clot properly, such as haemophilia
Your GP might want to test you for haemophilia or for other conditions such as anaemia.
See a GP now or go to A&E if:
- your nosebleed lasts longer than 20 minutes
- the bleeding seems excessive
- you’re swallowing a large amount of blood that makes you vomit
- the bleeding started after a blow to your head
- you’re feeling weak or dizzy
- you’re having difficulty breathing
Causes of a nosebleed
The inside of the nose is delicate and nosebleeds happen when it’s damaged. This can be caused by:
- picking your nose
- blowing your nose too hard
- the inside of your nose being too dry (because of a change in air temperature)
Nosebleeds that need medical attention can come from deeper inside the nose and usually affect adults. They can be caused by:
- an injury or broken nose
- high blood pressure
- conditions that affect how the blood clots or the blood vessels
- certain medicines, like warfarin
Sometimes the cause of a nosebleed is unknown.
Certain people are more prone to getting nosebleeds, including:
- children (they usually grow out of them by 11)
- elderly people
- pregnant women
How to stop a nosebleed yourself
- sit or stand upright (don’t lie down)
- pinch your nose just above your nostrils for 10 to 15 minutes
- lean forward and breathe through your mouth
- place an icepack (or a bag of frozen vegetables wrapped in a teatowel) at the top of your nose
If doctors can see where the blood is coming from they may seal it by applying a stick with a special chemical on it to stop the bleeding.
If this isn’t possible, doctors might pack your nose with special sponges to stop the bleeding. You may need to stay in hospital for a day or two for this.
When your nosebleed stops
After a nosebleed has stopped, try not to do the following for 24 hours:
- blow your nose
- pick your nose
- drink hot drinks or alcohol
- do any heavy lifting or strenuous exercise
Also, don’t pick any scabs that form (they help it to heal and prevent infection).
