Treatment depends on the specific cause. Some of the causes will disappear over time.
You may need to stop taking aspirin, ibuprofen, naproxen, or other medicines that may be causing gastritis, but only

as:
Antacids
H2 antagonists: famotidine (Pepsid), cimetidine (Tagamet), ranitidine (Zantac), and nizatidine (Axid)
