Hi Lin,

I'm in a 3 month bout of anxiety at the present time. I haven't had it like this for about 8 years and that was the first real bout with panic attacks. Through both periods, one day my bowel movements can be relatively normal, then the next I can have the trotts. If I haven't eaten anything and go later in the day mine can be yellow too. I think it's most likely the acid created in your stomach from the anxiety. This past week it's been like this for me. It does go though!

Hope this helps,

Mark.
