When acid refluxes from the stomach into the esophagus, it is known as gastroesophageal reflux disease (GERD). If stomach acid travels up the esophagus into the throat, it is known as laryngopharyngeal reflux (LPR).
Hoarseness (also called dysphonia) is an abnormal change in the quality of your voice, making it sound raspy, strained, breathy, weak, higher or lower in pitch, inconsistent, or fatigued, often making it harder to talk.
