GERD is not likely to be life-threatening. It can make performing daily tasks unpleasant at times, but you can likely find reprieve with proper care. If untreated, GERD could lead to additional GI issues. These include esophagitis (irritation of the esophageal lining) and Barrett’s esophagus, a disease that can damage the esophagus (the structure that links your mouth to your stomach). Getting the care required for this disease can help protect your overall health and wellness.
