Nasal Congestion
Nasal congestion is a blocked or stuffy nose caused by swelling inside the nose. Colds and allergies are common causes, but persistent one-sided blockage should be assessed.

Quick Reference Facts
In simple words
Nasal congestion is the feeling that airflow through one or both nostrils is reduced because the lining inside the nose is swollen or mucus is present.
It is usually short-lived with a cold or allergy. The pattern—seasonal, sudden, one-sided, or persistent—helps distinguish likely causes and when assessment is useful.
Common Causes
- A viral cold or another upper respiratory infection
- Allergy to pollen, dust mites, animals, mould, or an irritant
- Non-allergic rhinitis triggered by temperature changes, smoke, or strong smells
- Sinus inflammation, a medicine effect, or a structural nasal problem
Clinical Red Flags
Seek urgent medical attention at an emergency department or primary care clinic if you present with any of the following symptoms:
- Seek urgent help for severe breathing difficulty, swelling of the face or throat, severe headache with neck stiffness, or eye swelling or vision changes.
- Arrange a review for one-sided blockage that persists, repeated nosebleeds, reduced sense of smell that does not recover, facial pain or swelling, or symptoms lasting several weeks.
- Get advice before using a decongestant if you are pregnant, have heart disease, high blood pressure, glaucoma, or take regular medicines.
Lifestyle & Diet Support
Rest, drink fluids, avoid smoke and known triggers, and consider saline spray or rinse. A pharmacist can advise on allergy treatments or a short course of nasal decongestant; do not use decongestant sprays for longer than the product guidance because they can make blockage worse.

Differential Diagnosis Matrix
A clinician may consider allergy, infection, sinus disease, medication overuse, nasal polyps, or a structural cause. A blocked nose caused by decongestant overuse needs a different approach.
