I think my IBS started in my mid-20s I am now 41 and I can honestly say over the past year it’s gotten worse. I have had a colonoscopy and everything came out fine. Sometimes I know my triggers sometimes I don’t just depends on how my body wants to react. And on top of that I also have Gerd. But I don’t let it get me down just got to watch what I eat and take my meds. And usually a one-hour trip to the bathroom helps.
