Nasal polyps

Nasal polyps are painless soft growths inside your nose. They're not usually serious, but they can keep growing and block your nose if not treated.

Check if you have nasal polyps

Symptoms of nasal polyps include:

Nasal polyps can sometimes feel like a cold. But colds tend to clear up within a few days, whereas nasal polyps will not get better unless they're treated.

If your polyps block your sinuses (the air pockets around your nose) you may also have symptoms of sinusitis.

Non-urgent advice: See a GP if:

  • you think you may have nasal polyps
  • you have difficulty breathing
  • your symptoms are getting worse
  • you notice changes to your sense of smell

Treatment for nasal polyps

A GP should be able to tell if you have nasal polyps by looking inside your nose.

If you have nasal polyps, you'll usually be given steroid nose drops or a spray to shrink the polyps.

Sometimes, you may be given steroid tablets, usually for up to 2 weeks, to help relieve symptoms.

Make sure you follow the advice of the GP about how to use your medicine and how long to take it for.

Surgery to remove polyps

If there's no sign of improvement after about 12 weeks, the GP may suggest surgery to remove your polyps.

Most people who have surgery see an improvement, but it's common for polyps to grow back, usually within a few years.


You may need to keep using a steroid nasal spray after surgery to stop the polyps returning quickly.

How to make your own salt water wash to help unblock your nose
  1. In a bowl, mix 1 level teaspoon of salt and 1 level teaspoon of bicarbonate of soda in about 1 pint of cooled boiled water.
  2. Wash your hands.
  3. Stand over a sink, cup the palm of 1 hand and pour a small amount of the cooled mixture into it.
  4. Sniff the cooled mixture up 1 nostril and let it run out.
  5. Repeat sniffing at least 3 times up each nostril or until your nose clears up.
  6. You can gargle any remaining mixture to help clear the back of the throat.

Check the mixture is not too hot before sniffing. Do not swallow the salty mixture. It may make you feel sick.

These salt water washes are not suitable for children.
