Laryngitis
Laryngitis is a common disorder that involves acute or chronic inflammation of the vocal cords. Acute laryngitis may occur as an isolated infection or as part of a generalized bacterial or viral upper respiratory tract infection. Repeated attacks of acute laryngitis cause inflammatory changes associated with chronic laryngitis.

To prevent gastric reflux, which can lead to laryngitis, give the patient the following instructions:
Elevate the head of the bed (by elevating the mattress). Sleeping on additional pillows won’t be sufficient.
Avoid alcohol and coffee. Explain other dietary recommendations as needed.
Avoid eating for 3 to 4 hours before going to bed.
Take an antacid and a histamine-2 receptor antagonist as prescribed.
