I have had IBS for at least 5 years but have always been able to manage without the symptoms interfering too much with my daily functionning. Since having a baby four months ago, I've been significantly worse. Where I have a bad bout of diarrea every two weeks or so, sometimes with vomiting at the same time. Has anyone heard of pregnancy causing this type of worsening of symptoms. Does anyone have any advice. I'm trying to exclude all types of things from my diet. Has anyone heard of a relationship between breastfeeding and a worsening of symptoms. Any Advice?
