Acid Reflux disease can cause your throat to become very sore. This pain occurs because stomach acid leaves the stomach and rises to the lungs and the esophagus. The acid can become mixed with saliva and can affect your throat, causing you to lose your voice.

This refluxing of stomach acid can also cause changes to your voice by causing shortness of breath. This reduction in air available for speaking causes your vocal chords to strain because of the extra work it takes to speak. Over time, your vocal chords can become damaged and that will often permanently affect your voice. Your voice may become deeper, or it may become thin, with little volume.

Acid reflux can hurt not only your throat and vocal chords; it can also injure your lungs and other organs–including the heart.
