I ve been having a lot of diarrhea after eating. I ve also noticed some long stringy mucus stuff in it. The diarrhea almost looks fibery, like flakes. I really haven t noticed weight loss, but several people have told me I m losing weight, but I havent weighed myself in awhile. I m a 50 year old female, pretty healthy, and had my gall bladder out several years ago. Should I be concerned?
