floating stools, and also off and on diarrhea. I went to the doctor a month ago or so for a unrelated problem, and had blood work done. It all came back normal except for a few miniscule things. I'm 20 years old, in great health (other than this!) i exercise every day and have a very good diet, usually! Any ideas to what it could be? I'm thinking of making an appointment for it, but just wanted to hear ideas before.
