Another Complication of Reflux: Laryngeal Pharyngeal Reflux (LPR)
Many patients with throat discomfort are surprised when they are told that they have laryngeal pharyngeal reflux (LPR). Gastric acid can cause significant inflammation when it falls on the vocal cords. If this happens repeatedly, a person can be left with a number of bothersome throat problems, such as hoarseness, frequent throat clearing, coughing, or the sensation that there is something stuck in their throat. Many patients with LPR do not have any of the typical GERD symptoms. This has lead to some controversies and misunderstandings about LPR.
