What is the cause(s) of excess acidity in the stomach?
You would think this is supposed to reach a homeostatic and 'normal' acidity in a healthy individual that does not lead to any symptoms.
From what I understand you are saying the nausea can be caused by the ulcer/gastritis that is formed by the excess acid.
Do people have changes in acid levels over time , or temporarily during their life?
Another interesting question is does excess acidity in the stomach correlate with acid reflux? In other words, does it just swish around inside the stomach pack or does excess acidity also somehow precipitate the reflux reaction by some mechanism?
