I have had IBS (irritable bowel syndrome) for 35 years, but mostly very mild
and not very problematic since I was in my 20s. Now, in the past couple of years, I have g.i. symptoms I hardly ever had before-- heartburn, acid reflux, pain in my small and large intestines, occasional nausea. Diagnostic tests have not revealed a reason for this. But recently I have been wondering--could the g.i. symptoms be a side effect of anastrozole (arimidex)?
