Is this IBS or something else?

I posted a few days ago ago another forum about not being able to sleep because of needing a bowel movement. It's dawned on me that the not sleeping is just a symptom of the increased bowel movements which is the real issue.

I have been diagnosed with IBS for years BTW

In the last few weeks my bowel movements have increased quite a lot to 3-5 BMs every other day, and mostly at night - they have also been looser on the most part. On those nights I may go as many as 5 times between 7pm and 4am and like tonight, the consistency has gone looser with each bowel movement, though never going as far as watery - they are still solid, just a lot looser. I have also been feeling a bit nauseas in the last few days, though only during the times that I have 'needed' the bowel movements.

There has been blood a couple of times, though this has not really been on the stools themselves but more on the toilet paper and has been when I've had lots of bowel movements which I've felt hurting the anus entrance.

Various trips to the docs have been fruitless and I've started to worry myself sick about other things like colon cancer.

If these sounds familiar to anyone or you can shed any light from knowledge or hearing other people's experiences I'd be very appreciative of any input.

Thanks JoAnn, I've never been tested for celiac disease - I'll look into getting that done. Must admit I've heard people talk about gluten free diets but never looked into them all that mich - food for thought, pardon the pun!
