A constantly blocked nose is more than just annoying — it can affect your sleep, concentration, and overall wellbeing. Many people live with this condition for months or even years without understanding the real cause.

So what’s actually behind a chronic blocked nose?

The most common causes

1. Allergies (Allergic rhinitis)

One of the most common causes, especially in cities like London where pollen, pollution, and dust mites are widespread.

Typical symptoms:

  • Alternating nasal blockage
  • Frequent sneezing
  • Itchy nose and eyes
  • Watery eyes

Symptoms often worsen during certain seasons or in specific environments.


2. Sinusitis (acute or chronic)

Sinusitis is inflammation of the sinuses, which can become chronic if not properly treated.

Typical symptoms:

  • Facial pressure (forehead, cheeks)
  • Thick mucus (yellow/green)
  • Headaches
  • Reduced sense of smell

When symptoms last longer than 12 weeks, it is considered chronic sinusitis.


3. Deviated septum

A very common structural condition where the nasal septum is off-center, making airflow difficult.

Typical symptoms:

  • Constant blockage (often one side)
  • Difficulty breathing, especially at night
  • Snoring or poor sleep quality

Medication alone may not solve the issue — specialist evaluation is often needed.


How to identify the cause

Symptoms often overlap, making self-diagnosis difficult.

That’s why you may need:

  • A full clinical assessment
  • Allergy testing
  • An ENT specialist consultation

When should you be concerned?

Don’t ignore the issue if:

  • Your nose has been blocked for more than 2–3 weeks
  • You struggle to sleep or breathe properly
  • Over-the-counter treatments don’t work
