Gastroesophageal reflux disease is not considered life-threatening. It might sometimes make day-to-day tasks more uncomfortable, but you can often find relief with treatment. If left untreated, gastroesophageal reflux disease may lead to additional health issues. Some of these concerns involve Barrett’s esophagus, a disease that damages the esophagus (the structure that joins the mouth to the stomach), and esophagitis (inflammation of the lining of the esophagus). Receiving the care needed for this disease can help safeguard your health and wellness.
