For years I have sought the answer to this question without success:Exactly what causes a part of my stool--the first to come out during a bowel movement--to turn to clay?I've read everything, seen my gastro, taken everything and still. . . still the first third of every bowel movement is torture. The remaining two-thirds is easy and soft.But, that first part is hard, hard, hard. Just like clay. And no one can tel me why.Without knowing the answer, there's little more I can do to alleviate the problem Only suffer.Thanks for any help.
