If i don't go to toilet for poo because out or staying at house which toilet close to rooms does cause constipation i'm take fybogel to soften poo ?

It contributes: Ignoring the urge to have a BM may contribute to constipation. It may alter or eliminate that natural urge to defecate. Every person in the world has to "poo", & we all know there is an odor. Please do not ignore the urge to go when you have it, even if you are not in a convenient or ideal place. Add dietary fiber (bran, whole wheat, brown rice), water, exercise; better than Fybogel.
