Laryngitis

Laryngitis is when your voice box (larynx) becomes irritated or swollen. It usually goes away by itself within 1 to 2 weeks. It is often caused by an infection such as a cold or flu, or by overusing your voice. Long-lasting laryngitis can be linked to acid reflux, smoking or allergies.

What it is

Resting your voice, drinking plenty of fluids, and breathing in steam can help.

A hoarse voice lasting more than 3 weeks should be checked by a doctor.

Common signs

  • A hoarse voice
  • Sometimes losing your voice
  • An irritating cough
  • Always needing to clear your throat
  • A sore throat

How it is usually diagnosed

  • Usually based on symptoms
  • Examination of the larynx with a camera, if it lasts more than 3 weeks

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • ENT letters, if seen
  • Endoscopy reports

Questions to ask your doctor

  • How long should I rest my voice?
  • Could reflux or smoking be causing it?
  • When should I come back?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Difficulty breathing, noisy breathing, or difficulty swallowing saliva: call 112
