I have really bad GERD myself
and had an upper GI that showed mild gastritis
and esophagitis. It is a difficult problem. I also take ibuprofen at times for osteoarthritis inflammation in my jaws, etc., and that can be hard on my stomach. There are dietary measures one is supposed to take when you have GERD, like avoiding fried and fatty foods, avoiding spicy, black pepper, and citrus and other aggravating fruit, avoiding dairy and anything else that aggravates it.
