What is Waterbrash?

Waterbrash is a bitter acid taste in the black of the throat. It is invariably caused by hydrochloric acid coming up (refluxing) from the stomach into the throat, and may be associated with heartburn and burping. The reflux of acid may be caused by vomiting, overeating, rapid eating, excess alcohol, a hiatus hernia or a peptic ulcer. It is usually worse when lying down or bending over.
