About Laryngitis: Causes

Acute laryngitis refers to hoarseness or loss of voice that appears suddenly after a night of singing and shouting, or being exposed to a lot of cigarette smoke. This condition usually improves on avoiding whatever has been irritating the throat (like cigarettes) and by resting your voice. The common cold and influenza (the flu) are common causes of acute laryngitis, but it can also be a symptom of bronchitis, pneumonia, and measles. Hoarseness may also be part of an allergic reaction.

Chronic laryngitis lasts longer than a week, and comes back over time. This condition can involve permanent changes in the lining of the throat. These changes could be due to repeated attacks of acute laryngitis like those sometimes experienced by professional singers, or happen because of repeated exposure to smoke, dust, or other irritants. Chronic laryngitis can also be caused by allergies or gastroesophageal reflux disorder (when harsh stomach acids rise up into the esophagus and cause burning). Rarer causes of chronic laryngitis include cancer of the throat, non-cancerous tumours on the vocal cords, and non-cancerous wart-like lesions called papillomas that grow in the throat.
