Why do I have yellow stool?

There are instances in which an individual ends up with yellow stool. The stool is comprised of 75% water while the remaining components include fat, bilirubin, mineral salts, protein, bacteria, undigested food and mucus from the digestive tract.

What provides color to stool?

Bile and bilirubin provide stool with its normal brownish color. It is important to note that bilirubin is a byproduct of the red blood cells. It is generated in the liver and moves to the gallbladder where it combines with bile. From there, most of the bilirubin moves into the intestines where it is degraded by bacteria and eliminated via the urine or feces.

It is considered normal for the stool to change color. This is true since most have varied diet and changes in the diet can affect the stool. Yellow stool is oftentimes called as pale stool which can indicate various health issues.
