Since the first week in April, I have experienced watery stools. The pattern is as follows: approximately one cup of water, followed by appox. a half cup of runny, yellowish stool, followed by expelled gas. The frequency seems to be between 2 to 4 hour intervals but not consistent during my waking hours. I sleep fine. I have not changed my daily diet or routine. I have been taking a multi-vitimin(centrum), 1000 iu vitimin D, and a baby asprin for several years. There is no pain. I had a routine colonoscopy on 21 April with normal result. The color of my stools most recently have been a normal, brownish with varying degrees of liquidity.
