I have had IBS for almost 3.5 years now. Don't really have diharea much and never constipated, my ibs has always been needing to go too much in relation to stress, etc. i have been taking metamucil in combination with digestive advantage for 2.5 years now and it has worked wonders, i live a semi normal life. However, this past month my IBS seems to be getting worse, but for no apparent reason. It cant be stress, since im done with college for summer and only work an easy 20 hours per week. I eat all of the same foods ive been eating for years with no problems, and i have been avoiding bad ibs foods too. But tonite marks the 3rd time in a month that ive had horrible diarrea for no reason whatsoever. Someone please help me! Does IBS always get worse over time?
