Yes, I'm serious! (And don't you sometimes wonder anyway?)
You already know that your poop can reflect your physical, and sometimes even emotional, health. You may get constipation or have diarrhea when you eat something that "doesn't agree with you," or when you're super-nervous about something.
Separate hard lumps (very constipated).
Lumpy and sausage-like (slightly constipated).
Sausage shaped with cracks in the surface (normal)
Smooth, soft sausage (normal).
Soft blobs with clear-cut edges (lacking fiber).
Mushy consistency with ragged edges (inflammation).
Liquid consistency with no solid pieces (inflammation).
But if you see an abnormal color, like red or even black, that you can't explain based on what you ate or drank in the last day or two, you probably want to get that checked out.
