The Other David asks:
As I have been diagnosed with IBS, I have frequent sometimes debilitating bouts of diarrhoea. To my understanding, IBS causes chronic constipation in some people, with others diarrhoea (even still in some both, con. and dia.) I am one that has the 'bias' towards diarrhoea. Now, many times, when I have the runs, upon gettingover it, my stools have the appearance of being soft, chalky, and of a pale yellow colour. This lasts for a day or two, then evolves to become a beige colour, in turn leading to the so-called 'normal' appearance of a light to dark brown. What causes this discolouration? thanks.
Hello, and thanks for the question!
Sorry about the IBS. That's the pits.
Yellow, runny-ish stools are merely poop that didn't spend enough time hanging around in the large intestines. Your IBS caused a speed up in transit time, and the poo shot on thru without having enough time to firm up in the large intestine. As your colon chilled out, the poop had time to do what poop does naturally.
There are other causes of yellow stools, which I won't bore you with unless you are dying, because if you had these conditions, you wouldn't be sitting at the computer writing to Poonurse.
Hope this answered your question!
Please be advised that I am only a Poonurse. I am NOT a medical doctor. Any advice I give should be taken moderate skepticism. Please consult a REAL medical doctor if you feel you have a serious medical condition.

Poonurse is an RN with 25 years experience in labor and delivery. Her qualifications include seeing a lot of poop, and owning a computer. Also, she works in Michigan, which she calls the asshole of the universe, so that's another bit of credibility.
Got a question for her?
