To put it in the nicest way possible just wanted to know if anyone else suffers from stomach problems with their anxiety. Recently I have an urgency to get To the toilet I have been a mixture of Constipated but sometimes quite loose but not runny my stomach makes the most horrible noises and had flatulence and burping alot. Also my stools change colour on a regular basis from brown to yellow. Anyone else experience any of this with their anxiety. I am on omeprasol for acid reflux.
