It all started in 2020 July all of a sudden was diagnosed with diffuse gastritis (reason being too much black coffee n caffeinated pre-workout)... It took months (5-6) to kind of get back to normalcy... there's only one symptom(it's belching/burping) could feel the acid moving up and causing discomfort (this generally happens after few hours of eating (2-3 hrs) ... again it has started... same thing after few hours of eating (acid reflux (belching burping) ...is it gastritis or something else...how long can one take medication with side-effects (year's)... Kindly guide n provide solution( not able to workout to the best of my ability instead have switched over to simple excercise) like  walking... earlier use to do skipping, strength training n HIIT ...
