How people get chronic or erosive gastritis from advil. for me,just 2 pills cause stomach pain as warning sign to stop. others dont get warning pain?

Take NSAID with wate: Common pain relievers — such as aspirin, ibuprofen (Advil, Motrin IB, others) and naproxen (Aleve, Anaprox) — can cause both acute gastritis and chronic gastritis. Using these pain relievers regularly or taking too much of these drugs may reduce a key substance that helps preserve the protective lining of your stomach.Left untreated, gastritis may lead to stomach ulcers and stomach bleeding.
