Yellow diarrhea


Can be caused by a number of things, including infection, excess bile and poor digestion. Go see the doc and have a still culture done to check for microbes. If possible get a referral to the hospital to check for bile acid malabsorption (treated with Questran powder) and a stool test done to test pancreatic enzymes levels (treated with Creon tablets).
JohnaB hi thanks for your reply. From what I read from answers, it certainly sounds like "bile". I had my gall-bladder taken out years ago and apparently this yellow diarrhea is one of the results. I had this problem for 5 years and thought it was the result of a sea sickness injection I had - but maybe it prompted something else to happen. Or maybe it was a coincident. I am off to the quack monday. Wish me luck. Thanks again.
