Understand

Nasal polyps are soft, painless growths from the lining of the nose or sinuses.

Blocked or runny nose, postnasal drip, reduced smell and taste, snoring or sinusitis may occur.

Long-term inflammation contributes; asthma and aspirin sensitivity are associated, but the exact cause is often unknown.

A clinician examines inside the nose; one-sided disease needs particular attention.

Nasal endoscopy, CT and sometimes allergy tests or sampling define extent and alternative diagnoses.

Polyps can enlarge, block the nose and recur after medicines or surgery.

Saline rinses and nasal steroids are usual; a short oral-steroid course or surgery may be offered.

Seek assessment if blockage persists, worsens or smell changes.

One-sided blockage with bleeding, facial swelling, visual change or major breathing difficulty needs prompt assessment.

A procedure linked to a condition does not establish an indication for your individual situation.
