Laryngitis is an inflammation of the larynx, commonly known as the voice box. It often results in a hoarse voice or loss of voice, and can be caused by infections, overuse of the voice, or irritants like smoke. Symptoms may also include a sore throat and a dry cough. Most cases of laryngitis are temporary and improve with rest and hydration. Treatment typically focuses on relieving symptoms, such as using humidifiers or throat lozenges. In chronic cases, addressing underlying issues, like allergies or acid reflux, may be necessary for recovery.
