 This stimulates the bowel muscles to move the stool. Don't take it if your stool is not soft. It could hurt. Your stool softeners are your colase, your docusate sodium. That brings the water into the stool to make it easier to pass. Your bulk laxatives are your water-absorbing fiber, which we just spoke about. That helps stimulate the bowel to pass and softens the stool, so it's a twofer. And then you've got your lubricant laxatives. That kind of lubricates it, so like mineral oil.
