This is a chronic disease that occurs when stomach acid or bile flows into the food pipe and irritates the lining. Acid reflux and heartburn more than twice a week may indicate GERD. Symptoms include burning pain in the chest that usually occurs after eating and worsens when lying down. Relief from lifestyle changes and over-the-counter medication is usually temporary. Stronger medication may be required.
