What are nosebleeds during pregnancy?
Nosebleeds, sometimes called 'epistaxis', occur when the tiny blood vessels inside your nose burst.
Nosebleeds during pregnancy are a common problem. You may experience nosebleeds more often if you're pregnant, even if you haven't had them often in the past.
Although nosebleeds can be alarming, in most cases there's no need to worry. You should be able to manage them yourself at home.
What are the symptoms of nosebleeds during pregnancy?
Symptoms of nosebleeds in pregnancy are not usually different from a regular nosebleed. You may have sudden bleeding from one or both nostrils. Blood flow can be light or heavy. Sometimes you may taste or feel blood running down your throat.
Nosebleeds may last from a few seconds to more than 10 minutes.
Nosebleeds sometimes happen while you're sleeping. You may wake up feeling the blood going down the back of your throat. When you sit up, the blood will then come out of your nose.
What causes nosebleeds during pregnancy?
There are several reasons why nosebleeds are more common during pregnancy. These are related to the changes in your hormones during pregnancy.
How can hormonal changes lead to nosebleeds?
Increased oestrogen levels during pregnancy cause the delicate blood vessels in your nose to dilate (widen), become more congested and likely to rupture (burst).
Progesterone also increases the amount of blood circulating in your body (your blood volume). This can increase the pressure in the tiny blood vessels in your nose, causing them to burst, resulting in a nosebleed.
Other hormones that are increased in your body during pregnancy can cause your blood vessels to relax and widen. This causes more blood to flow around your body putting extra pressure on the delicate blood vessels in your nose.
Other causes of nosebleeds
It is good to remember that even in pregnancy, a nosebleed may be caused by an issue unrelated to pregnancy.
Nosebleeds can occur due to damage caused by:
- picking your nose
- blowing your nose too hard
- dry air (such as from heaters or cold weather)
- a foreign object in your nose
Nosebleeds can also be due to accidents and medical conditions such as:
- an injury or broken nose
- hypertension (high blood pressure)
- conditions that affect your blood vessels or how your blood clots
- certain medicines
When should I see my doctor?
If you have a severe nosebleed that doesn't stop, contact your doctor immediately or call triple zero (000) and ask for an ambulance.
If you lose a lot of blood during a nosebleed, see your doctor, as this may be a sign of a bleeding or clotting disorder that needs treatment.
You should go to hospital or call an ambulance if:
- your nosebleed lasts longer than 20 minutes
- there seems to be a large amount of blood
- you have swallowed a lot of blood and vomited (thrown up) more than once
- your nosebleed started after you hit your head
- you're having trouble breathing
- you feel weak or dizzy
You should speak with your doctor or midwife if you are getting nosebleeds frequently. They will check to see if there are any underlying issues causing your nosebleeds.

How is the cause of nosebleeds in pregnancy diagnosed?
Your doctor will ask questions about your symptoms and recent health. Let your doctor know if you are taking any medicines. Your doctor may ask about:
- how often you get a nosebleed
- if it is always from the same nostril
- how long your nosebleeds usually last
- how much blood you lose during a nosebleed
Your doctor will examine your nose and may perform a general physical examination.
In some cases, your doctor may recommend a blood test to check for a medical issue that is causing your nosebleeds.
If you're getting severe nosebleeds, your doctor may refer you to an ear, nose and throat (ENT) specialist.

How are nosebleeds during pregnancy treated?
Nosebleeds usually can be easily managed with first aid. To take care of a nosebleed:
- Sit up and lean forward slightly.
- Firmly pinch your nose below the bridge (the bony part of your nose).
- Breathe through your mouth.
- Keep pinching for 10 minutes.
- If any blood enters your mouth, spit it out.
- You can put an ice pack on your forehead and the back of your neck.
- After the 10 minutes is up, let go and see if the bleeding has stopped.
If bleeding starts again, get medical advice. If bleeding doesn't stop after 20 minutes, seek medical help.
In the past, other ways of dealing with nosebleeds were often used, but these aren't considered effective. Follow the advice above, and don't:
- tilt your head backwards — the blood may flow down your throat and make you sick
- lie down
- put tissues or cotton wool up your nose
Cases of more severe nosebleeds that won't stop can be treated in hospital. Treatment may include:
- packing your nose with special gauze or balloons
- medicines to constrict the blood vessels in your nose
- medicines to encourage blood clotting
What should I do after a nosebleed?
In the 24 hours after a nosebleed, you should try to avoid:
- blowing your nose
- picking your nose
- bending down
- vigorous exercise
- drinking hot drinks or taking a hot shower or bath
- drinking alcohol
- taking NSAIDs (non-steroidal anti-inflammatory drugs)
What are the complications of nosebleeds during pregnancy?
Nosebleeds can be upsetting, but generally there's nothing to worry about.
As long as you don't lose a lot of blood, you can treat your nosebleed at home. In most cases, a nosebleed won't harm you or your baby.
Can nosebleeds in pregnancy be prevented?
Nosebleeds in pregnancy can't always be prevented, but there are things you can do to reduce the chance of them happening.
Avoid rubbing or picking the inside of your nose.
You may find that you get more nosebleeds in winter when the air is drier. Try using a humidifier in your home to help moisten the air. Saline spray and saline nasal gel may also help.
If there is an underlying cause of your nosebleeds, managing it can prevent future nosebleeds.
Will my nosebleeds stop after I give birth?
Your nosebleeds may become less frequent as your hormone levels return to normal after birth.
