I'm a 19 year old and I recently started taking Metamucil about 4 days ago to aid my symptoms of ibs. Its been working great as I no longer have the stool consistency ranging from pebbles to logs. However, I have noticed that my stools have contained red tissue looking material (best way to describe it--not tissue paper but bodily tissue) the stools are soft and when broken apart it is stringy and floats away by itself as it doesn't seem to be part of the stool. What is this red stringy tissue like stuff in my stool, any cause for concern and has anyone else had anything similar to this? I've noticed this too about a year ago also when I was either getting over or suffering from an IBS flareup but it went away to best of my knowledge.

Also might mention that part of my stool was green. Green stools started at the end of the previous bowel movement and only a small portion of this one was green. I was told this was due to the bowel not being caught up to the quickened digestive process due to the Metamucil and it goes away shortly. Any truth to that?
