I have explosive diarrhea for a number of months 6 to a year. Many times there ends up a white kidney shaped substance with a yellow tint to it that is very soft, I would like to ask what this is and if I need to have it checked out I've had CT scans of my stomach I've had blood work on my liver and my kidneys etc I have not mentioned this to my physicians but I will at my next appointment but I'm running it by you first to see if you have any ideas it seems that there are a lot of people with the same complaints I am 55 years old
