Nasal polyps are swellings in the lining of the nose usually associated with an allergy, infection although the it is not always known why some people get them and others don’t.

Nasal polyps typically cause a blocked nose, usually on both sides. They also cause a reduced sense of smell, sneezing, a runny nose  and fluid dripping to the back of the nose (post nasal drip). Most nasal polyps are allergic nasal polyps and can be shrunk with nasal sprays, nasal drops and sometimes steroids taken as tablets. Surgery is usually advised if the polyps cause nose bleeds, if they are just on one side or if they cannot be shrunk (with nasal sprays and or drops) well enough to help you breathe adequately. Endoscopic sinus surgery to remove polyps is the best operation for polyps as it is precise and helps open up the sinuses to keep them well ventilated.
