Nasal polyps are soft, jelly-like overgrowths of the lining of the sinuses. They look like grapes on the end of a stalk. They occur in around 1 in 200 people, mostly by the age of 40 years.

Symptoms of nasal polyps

Nasal polyps do not always cause symptoms. As they usually grow through the tunnel that connects the sinuses to the nose, the result is often a blocked nose. Nasal polyps can block the tunnels connecting the nose to the sinus cavities, and this can lead to sinus infections.

Causes of nasal polyps

The cause of nasal polyps is unknown, but inflammation in the sinuses (from allergy or infection) may trigger polyps and make them grow faster. Sometimes other conditions such as sinus infections, asthma and allergy to aspirin can occur more often in people with nasal polyps.
