can IBS C become IBS D?
I've been diagnosed with IBS-C and took Zelnorm for 2 months. My BM have become more regular but i'm still experiencing major bloating and discomfort. I also feel like i have to make a BM almost all the time. Recently i've been experiencing very very loose bowels which is becoming more frequent. I'm not on Zelnorm any more, so that isn't causing it. is it common/ possible for IBS types to change?
