10 Causes of Hiccups
Cause #9: Laryngitis
Laryngitis refers to inflammation of the voice box or larynx. Patients with laryngitis may experience fever, cough, hoarse voice, difficulty swallowing, and sore throat. In most cases, the symptoms usually resolve in less than 2 weeks. Acute laryngitis refers to laryngitis that lasts less than 3 weeks while chronic laryngitis refers to laryngitis lasting more than 3 weeks.
Acute laryngitis is most often due to a viral infection causing an upper respiratory tract infection. Chronic laryngitis causes include allergies, acid reflux, tuberculosis, smoking, sarcoidosis, and rheumatoid arthritis. Laryngitis can also cause hiccups if the phrenic or vagus nerves that supply the diaphragm are affected.
