LPR is a condition where acidic stomach contents travel from your stomach, back up the food pipe (oesophagus) to the level of the voice box (larynx).You may be wondering how it's different from Gastroesophageal Reflux Disorder (also known as GERD, the more widely known type of acid reflux).Both LPR and GERD are similar, but not the same. In GERD, stomach contents travel up the food pipe (oesophagus), but do not reach the throat.Hence, the predominant symptoms of GERD are in the stomach and chest regions (bloatedness, burping, indigestion), rather than in the throat as with LPR.
