I have had chronic constipation for some time now. I have been able to improve the symptoms by taking fiber supplements, including Benefiber and Metamucil fiber wafers. I am now having regular bowel movements, however I still have the feeling that the bowel movement is incomplete. The stool is sizeable and of the desirable softness, however I have the feeling that there is more, hardened stool behind it that is not coming out. I do not feel fully emptied and cleaned out after a bowel movement. Does anyone have an idea of what kind of constipation I have and what can be done to treat it?
