If you have excess acid but don't experience heartburn or reflux etc could it be going down and causing painless D?Can you be tested for this?

 

[flux]

You could have a gastrinoma, tumor in the pancreas causing massive secretion of gastrin and excess acid. This could cause painless diarrhea, but it would almost cause some sort of ulcer in the stomach/duodenum too.A blood test for gastrin level would detect it.See http://www.pennhealth.com/ency/article/000325.htm for more info.
