I have had IBS D since I was in my teens and it was always just cramps followed by Diarrhea. About 10 days ago suddenly I had some constipation which has never really been an issue for me as I have always been pretty regular and since then I have had watery loose stools which is usually preceded by a bit of cramping. I am going to the toilet less than normal and sometimes I go and nothing happens and sorry about the TMI but my bowel movements are reduced in volume and not formed. I am worried it’s Bowel Cancer as my grandfather died of that or maybe my IBS is changing.
