1. Gastroesophageal Reflux (GERD): The Silent Culprit
One of the most common causes of chronic throat phlegm is gastroesophageal reflux (GERD). This condition occurs when stomach acid flows back into the esophagus—the tube connecting your stomach to your mouth.
While many associate GERD with heartburn, it often presents more subtly. Symptoms can include persistent phlegm, a chronic dry cough, or a constant tickling sensation in the throat.
Why does this happen?
When stomach acid irritates the lining of the esophagus and throat, the body produces extra mucus as a protective response. Over time, this can lead to chronic inflammation and excess phlegm.
Signs to watch for:
Symptoms worsen after meals or when lying down
