@johnwes5819 Has anyone checked your liver and gall bladder function? The liver produces bile which emulsifies fats during digestion, and it is what gives color to your stool. The bile is stored in the gall bladder and squirts it into the small intestine through the bile duct. If anything is blocking the duct such as gallstones, it will prevent some of the bile from getting through. Gall stones can become huge like the tip of your finger. I don't have them, but a friend of mine has had them and she was very ill before surgery removed them. If the timing of how fast things move through the intestines is sped up, the stool can be lighter. The stool is actually white in color if there is no bile. that of course is a question to ask a doctor because one cause of a blocked bile duct could be pancreatic cancer that is in the area and a mass could compress the duct. I also sent you a message.
