An ideal bowel movement is medium brown, the color of plain cardboard. Stool that is pale or grey may be caused by insufficient bile output due to conditions such as gallstones, hepatitis, chronic pancreatitis, or cirrhosis. Bile salts from the liver give stool its brownish color.
As digested matter and waste move through the colon it will turn from green to yellow and eventually to brown â which is the normal color for a stool. So, green poop can mean your stool has moved through your system too quickly for the bile to change it from green to brown. In medical circles this is often referred to as ârapid transit timeâ. Thatâs why diarrhea can look green because it goes through your digestive far more quickly than a normal stool.
