Catarrh is a build-up of mucus in areas such as your nose, throat or sinuses (spaces behind your nose, cheeks and forehead).
Symptoms of catarrh include a blocked or runny nose, needing to clear your throat regularly and a reduced sense of smell.
Catarrh often gets better on its own. Avoiding things that trigger symptoms, drinking plenty of water and rinsing your nose with salty water can help.
Common triggers for catarrh include a cold, hay fever and growths in your nose (nasal polyps).
