Frequent heartburn, evidence of esophageal irritation or inflammation, blood or weight loss may be associated with a more severe problem known as gastroesophageal reflux disease, or GERD.
What is GERD?
GERD is a physical condition in which stomach acid flows back up into the esophagus and produces a burning sensation behind the breastbone that moves up toward the neck and throat. It can also create a sour taste and the sensation of food re-entering your mouth. The main symptom of GERD is an uncomfortable feeling of burning, warmth, heat or pain just behind the breastbone, commonly referred to as heartburn.
