Is there a health science of poop? Serious responses only.?

Question

I want to get more information on how you can determine certain medical conditions and overall well being by poop- as in how soft it is, the many different textures it can have, what does light vs dark poop tell you, what does it mean when some poop have a really strong smell, how often should we be pooping, etc.

If anyone knows any good websites or books for this kind of information that would be great.
