Many people first notice gastroesophageal reflux disease (GERD) when a burning feeling rises behind the breastbone after meals or when lying down, sometimes with a sour taste in the mouth from stomach contents coming back up. Others pick up on quieter clues: a dry cough at night, hoarseness in the morning, a “lump in the throat” sensation, or chest discomfort that mimics heart pain but tends to worsen after eating and improve with antacids. If these symptoms occur more than twice a week, wake you from sleep, or persist despite over‑the‑counter remedies, those are common first signs of GERD and a reason to check in with a clinician.
