Background: Currently Gastroesophageal reflux disease (GERD) is the most common esophageal disorder, accounting for nearly 75% of all patients with esophageal disorders and around 25-30% of the general population in the west. Most studies from India suggest that these might be less in the Indian population. Most but not all patients with GERD are relieved by treatment with proton pump inhibitors and other anti-reflux treatment. Upper Gastrointestinal endoscopy also known as esophagogastroduodenoscopy (EGD) is the best test for the evaluation of the proximal gastrointestinal tract.
