Reflux disease is a chronic condition in which stomach acid flows back into the esophagus, leading to heartburn, irritation, and ongoing discomfort. This backward movement occurs when the lower esophageal sphincter becomes weak and allows acid to escape upward. Symptoms often worsen after meals, while lying down, or when bending forward. Because it can cause long-term inflammation if not managed properly, timely evaluation and appropriate Reflux disease treatment in Chennai play an important role in protecting esophageal health and improving overall comfort.
