Reactive gastropathy is a condition that affects the stomach and can cause discomfort and pain. There are several synonyms for this condition, including non-erosive reflux disease (NERD), functional dyspepsia, and gastritis. NERD is a form of acid reflux that doesn't cause erosion of the esophagus, while functional dyspepsia refers to a similar condition that causes indigestion and discomfort. Gastritis refers to inflammation of the stomach lining, which can be caused by various factors including infection, alcohol consumption, and certain medications. While these conditions may have different underlying causes, they share similar symptoms and can be treated with similar methods including lifestyle changes and medication.
