Non-erosive reflux disease (NERD) endoscopy is defined by reflux symptoms with what endoscopic finding?

Explanation:
The key idea is that non-erosive reflux disease presents with reflux symptoms but no visible injury to the esophageal lining on endoscopy. That means the endoscopic appearance is normal, even though the patient experiences heartburn or regurgitation. If the endoscopy showed erosive esophagitis, it would reflect mucosal injury; Barrett's esophagus would show a metaplastic change in the distal esophagus; and an esophageal stricture would present as a narrowed segment from scarring. So the best endoscopic finding for NERD is a normal endoscopy.
