I went off my acid reflux meds for a year when I stopped having heartburn & couldn’t afford the meds. After awhile had shortness of breath, which I didn’t recognize as a symptom, and my voice has changed. Can’t sing now (not a great loss for the world but I miss it) and people often call me “sir” on the phone. They haven’t ordered any GI studies or anything but I would urge anyone w acid reflux to become educated about all of the symptoms & keep up on their status. Just sayin...
