What should you know about prolonged nasal congestion?

A stuffy or blocked nose happens when the lining inside the nose becomes swollen or produces extra mucus. A common cold may settle, while allergic rhinitis can continue when triggers such as pollen, mould, or house dust mites remain present. Sinusitis can add facial pressure, reduced smell, or thick discharge. Persistent mouth breathing may disturb sleep; loud snoring and pauses in breathing deserve discussion because obstructive sleep apnoea can involve blocked nasal airflow.

Notice whether symptoms change with seasons, rooms, pets, dust, or lying down. Saline nasal rinses may loosen mucus; use sterile, distilled, or previously boiled and cooled water and clean the device as directed. Keep hydrated and avoid smoke and other irritants. A pharmacist or clinician can explain whether allergy medication or another nasal treatment fits your symptoms. Do not use decongestant sprays for longer than the product instructions, because overuse can worsen blockage.

Arrange a medical assessment when congestion persists, keeps returning, affects sleep, or comes with facial pain, fever, reduced smell, or one-sided obstruction. Seek urgent help for trouble breathing, swelling around an eye, severe headache, confusion, or marked illness. A clinician may examine the nose and throat, review medicines and allergies, and decide whether further testing is useful.

Ask what cause best fits the pattern, whether your medicines could contribute, which nasal treatment is suitable, and how long to try it before review. Mention snoring, sleep disruption, facial pressure, bleeding, or a change in smell.
