Catarrh is a build-up of mucus in your nose and sinuses and phlegm in your throat. It usually clears up by itself but see a GP if it lasts longer than a few weeks.

Check if you have catarrh

You may get catarrh if you have an infection like a cold, flu or sinusitis.

Symptoms of catarrh include:

  • a constantly blocked nose
  • feeling like there's a lump or something stuck in your throat
  • a frequent need to swallow or cough to try to clear your throat
  • a feeling that mucus is slowly dripping down the back of your throat (postnasal drip)
  • a crackling feeling in your ears

These symptoms usually only last a few days, but sometimes they can last longer.

Things you can do to help ease catarrh

Although catarrh can be annoying, phlegm and mucus are not harmful and are the body's way of clearing infection.

It usually goes away by itself, but there are some things you can do to help ease the symptoms.

  • drink plenty of water

  • sip ice cold water when you need to clear your throat, rather than coughing or swallowing

  • try using a humidifier to help loosen the mucus in your nose and throat

  • try using an extra pillow in bed so you sleep in a more upright position, rather than lying flat

  • try gargling with salt water

Treatments from a GP

A GP may suggest trying treatments for catarrh that you can get from a pharmacist, like decongestant medicines and salt water nose rinses.

If your catarrh is caused by nasal polyps, a GP may prescribe steroid spray or nose drops. If these do not work, surgery may be needed to remove the polyps.

Causes of catarrh

Catarrh is your body's natural reaction to things like infection.

The lining in your nose, sinuses and throat becomes swollen and creates more mucus than normal.

Causes of catarrh include:

  • infections like cold, flu and sinusitis
  • pollution and cigarette smoke
  • allergic reactions to things like pollen, dust and pet fur
  • conditions that affect the nose, such as nasal polyps
