Dear Dr. Jahn,
I have heard acid reflux can lead to throat tension. Is this true? How so?
This is my clinical observation: reflux is often associated with an elevated larynx, which is due to increased muscle tone.
My explanation for the connection is this: when the mucosa of the pharynx is inflamed by reflux, it irritates the underlying muscles.
If the tone of the muscles attached to the pharynx and larynx is increased, the net effect is that the larynx moves up (there are many more elevators of the larynx than depressors).
I think it is a reflex irritation, not a direct effect of the gastric juice on the muscles themselves.
The problem of course is, once you learn to phonate with higher muscle tension (whatever the cause), this may become your norm, and even if the reflux is completely controlled, you need to actively unlearn this method of phonation.
