Gastroesophageal reflux disease (GERD), several people face this case of indigestion from time to time. But when it occurs repeatedly, it could be indicative of a more serious condition called gastroesophageal reflux disease, or GERD.
Gastroesophageal reflux disease (GERD) happens when a muscle at the end of your esophagus does not close properly. This allows stomach acids to flow back, or reflux, into the esophagus and aggravate it.
