Is it normal for people with IBS to have a pattern that migth result in Diahrea during some cycles and then also suffer from Constipation during another cycle with IBS.When my doctor first diagnosed me with IBS I would have the urgency with Diarehha after meals. Then I took soem meds and thing s seem to get better.Then for the most part no D flare ups or anything unless I messed with cdrtain foods, but then a year or two later I was dealing with Constipation(Going only ever 2-3 days instead of daily) which my doctor also thought might be caused by taking Tricor.So again are IBS sufferers only supposed to have issues with D or C with flare ups or can it alternate?
