1. Gastroesophageal Reflux (GERD): The Silent Culprit
One of the most frequent causes of chronic throat phlegm is something you might not even associate with your throat: gastroesophageal reflux, or GERD. This is a condition where the acid from your stomach travels back up into your esophagus, the tube connecting your stomach and your mouth. While many people think of GERD as causing that classic fiery heartburn in the chest, it often presents in a much more subtle, or “atypical,” way. This includes that persistent phlegm, a chronic dry cough, or a constant tickling sensation that makes you want to clear your throat.
