I noticed yesterday after a bowl movement that there was a small chunk of white alongside my stools in the toilet. It was not toilet paper as I had not thrown any in yet. It was about the size of quarter and had a little grayish tone to it. Am I crazy or is this normal? I touched it with the toilet brush and it sunk and disolved a bit. I was diagnosed with IBS with diahrrea a few years ago and have since changed my diet and am eating healthy and taking a multi vitamin and have had normal stools since, except for some bouts of constipation. The past few weeks I have had some diahrrea, but I relate that to my coffee intake.( I never drank coffee before and I have started .) I am 22 years old and I really don't want to go to the doctor to ask him about this.
