Laryngitis is a voice disorder relating to larynx inflammation or voice box. Many factors can cause it, often accompanied by a persistent urge to clear the throat.
Acute (short-term) laryngitis is usually caused by a virus, such as the common cold or flu virus, and usually resolves on its own. It may also be caused by excessive throat-clearing, shouting, or inhalation of irritants.
Chronic (long-term) laryngitis usually results from physical strain on the vocal cords, such as repeatedly shouting or singing, and is characterized by recurring voice problems.
Symptoms of laryngitis can range from mild hoarseness to complete loss of your voice, as well as difficulty speaking, swallowing, and a sore throat.
Treatment for laryngitis depends on the severity and the cause, but in some cases can include vocal rest and the avoidance of irritants such as cigarette smoke and alcohol.
In more severe cases, laryngitis can lead to vocal cord lesions, vocal cord paralysis, and larynx nodules or polyps. It may require more aggressive treatments such as surgery or vocal therapy.
While it is possible to become infected with laryngitis from another person, it is more likely to be contracted by long-term larynx irritation.
Laryngitis can indicate other underlying medical conditions, such as allergies, chronic infections, and acid reflux.
Bacterial laryngitis is uncommon and usually caused by a severe infection.
Smoking and excessive alcohol consumption are major risk factors for laryngitis.
To reduce irritants, it is important to keep the air inside your home clean and avoid areas containing contaminants such as secondhand smoke.
