Causes of laryngitis
Acute laryngitis is frequently of viral origin. However, it can be bacterial or mycotic (caused by a fungus).
The causes of chronic laryngitis are:
- Prolonged exposure to irritating substances (chemicals, allergens or smoke);
- Excessive and straining use of the voice (as in singers or teachers);
- Chronic sinusitis;
- Gastroesophageal reflux disease (GERD);
- Excessive alcohol consumption;
- Use of inhaled corticosteroids;
- Radiotherapy to the neck area;
- Cancerous lesions of the larynx.
Causes of laryngitis in children:
- A seasonal virus;
- A bacteria, haemophilus influenzae (becoming more rare due to vaccination against it);
- A laryngeal spasm linked to a coughing fit;
- Diphtheria (very rare, as children are usually vaccinated);
- A virus that causes another disease such as measles, mumps or rubella. Chickenpox, flu or herpes virus infections can also cause laryngitis.
- An inhaled foreign body.
