Laryngitis: Causes, Symptoms, and When to See a Doctor

Laryngitis is an inflammation of the larynx, or voice box. It can be caused by a variety of factors, including:

* Viral infections: The most common cause of laryngitis is a viral infection, such as the common cold or flu.

* Bacterial infections: Bacterial infections, such as strep throat, can also cause laryngitis.

* Allergies: Allergies to pollen, dust, or other allergens can cause laryngitis.

* Irritants: Irritants such as smoke, dust, or chemicals can cause laryngitis.

* Overuse of the voice: Straining the voice, such as by yelling or singing for long periods of time, can cause laryngitis.

* Gastroesophageal reflux: Acid reflux from the stomach can irritate the larynx and cause laryngitis.

Symptoms of laryngitis can include:

* Hoarseness

* Sore throat

* Difficulty swallowing

* Cough

* Loss of voice

* Fever

* Fatigue

* Headache

Treatment for laryngitis typically involves:

* Resting the voice

* Drinking plenty of fluids

* Avoiding irritants

* Using a humidifier

* Taking over-the-counter pain relievers, such as ibuprofen or acetaminophen

In some cases, antibiotics may be necessary to treat a bacterial infection.

Laryngitis is usually a self-limited condition that resolves within a few weeks. However, if symptoms persist or worsen, it is important to see a doctor.
