My mom’s nausea seems to correlate with her anxiety and depression. When they are treated, she does fine, but when she’s in a cycle, she complains of almost constant nausea.

Some forums on Reddit seem to suggest that only 0.01% of gastritis is due to excess acidity. I can understand needing to reduce acid to heal an inflammation temporarily, but has it been shown that gastritis actually forms due to excess acidity, or is it rather exacerbated by even normal levels of acidity? I did find interesting the seasonal and hormonal variation, but I wonder if that is not accounted for by the body. In other words, would people have moderate symptoms that come on suddenly due to this natural variation, assuming it wasn't an acute injury like overdose of alcohol. I suppose aging and other factors could make us more sensitive to a process that was going on before.

I suffered with slight nausea from the pain medication that I was taking for my back muscle spasm. I quit the pain meds because they were not helping and my doctor prescribed Famotidine. It took a few weeks but it cleared up and has never returned.
