How do you get laryngitis?

Laryngitis is an inflammation of the larynx (voice box). It is typically caused by a viral infection, such as the common cold or influenza, or by vocal strain. In some cases, laryngitis can be caused by bacterial infections, allergies, or gastroesophageal reflux disease (GERD). Common causes of laryngitis include:

- Viral infection: Laryngitis is commonly caused by viruses like influenza, adenoviruses, and respiratory syncytial virus (RSV). These infections can lead to inflammation and swelling in the larynx.

- Bacterial infection: Although less common, bacteria such as Streptococcus pneumoniae and Haemophilus influenzae can also cause laryngitis. Bacterial infections may require antibiotic treatment.

- Vocal strain: Overusing your voice, such as by talking loudly or singing excessively, can strain your vocal cords and lead to laryngitis.

- Allergies: Allergies to pollen, dust, and other allergens can cause the throat to become irritated and inflamed, leading to laryngitis.

- Smoking and alcohol consumption: Smoking and excessive alcohol consumption can irritate the vocal cords and make them more susceptible to infections and inflammation.

- Acid reflux or gastroesophageal reflux disease (GERD): When stomach acids back up into the throat, it can irritate and inflame the vocal cords, causing laryngitis.
