Gastritis is a medical term for inflammation of the lining of the stomach. It means that white blood cells move into the wall of the stomach as a response to some type of injury. Gastritis has many underlying causes, from infection with the bacterium H. pylori, bile reflux, or excessive consumption of alcohol or certain foods or drugs like aspirin.
Apparently Dexilant raises potassium levels. Maybe something similar is happening with you?
There is even a FODMAP IOS app that is handy for checking the contents of such things like sugar alcohols in foods.
These sugar alcohols are a common cause of IBS & other digestive problems.
