Color Matters Too
As you might have observed at one point or another, stool color can differ — a lot — depending on what sorts of food you’ve ingested and other elements. Patients get full work-ups for bright red stool that turned out to be nothing more than the passing of beets. Leafy vegetables could cause green stool, whereas certain medicines could make your waste look white or clay-colored. Look out for jet-black stool. Though it could possibly be from something as harmless as black licorice or iron supplements, the color might be an indication of bleeding in the upper gastrointestinal tract.
