Can chronic gastritis (not from hpylori) be from my lupus? Egd multiple times shows gastritis but no known reason... I wish I could drink coffee again

Chronic gastritis. Lupus is a possibility if no other cause found. It's an autoimmune disorder and there are causes of autoimmune gastritis causing acid producing cells to due resulting in gastric cell lining thinning and atrophy. A biopsy during egd may be helpful to determine the cause of gastritis.
