I realize my diet isn't the best, even though I'm watching my calories, but I really wish I could have normal BMs again. Recently I had stool that was this strange sort of light brown/greenish color, floated, and was really loose. I've been having floating stools on and off for years and I'm terrified that I have stage 4 pancreatic cancer ravaging my body and I'm not long for this world. Please help me....
