Q. The past weekend I had terrible diarrhea. At first I assumed it was a virus and after three days I started feeling a bit better. But the last two days my stool is almost white, like dried up dog poop.
I have never seen this before and would like to know what could cause eggshell-colored stool. I recently started a new blood pressure medication that seems to be causing constant gas. The drug is something like hydralazine + HCTZ.
A. Pale poop is a warning signal and should always be brought promptly to a doctor’s attention. The normal brown color comes from bile, a secretion from the liver that aids in digestion.
A white or light-colored stool suggests there could be a problem with the liver, pancreas, gallbladder (which stores bile) or bile duct that carries it to the small intestine. Your new blood pressure medicine can cause diarrhea and liver inflammation. Contact your doctor right away.
