What could cause "Mild Reactive Gastropathy"?

[quackers57]

A little background. I was diagnosed w/gerd way back in 1994. I had an endoscopy done last week.  I will see my doctor for a follow up shortly. The results from pathology were "Gastric mucosa with decrease in surface mucin, foveolar hyperplasia, minimal edema and mild patchy congestion".  No H pylori - everything else looked ok. My doctor said right after the scope you have gastritis. Reading about this on the internet is that mild reactive gastropathy is caused by NSAIDs, bile reflux or abusing alcohol.  I don't drink alcohol or have bile reflux. Sometimes but not often I do use advil or bayer aspirin but it is minimal.  Is there anything else that would cause "mild reactive gastropathy"  Thank you
