I had colitis and gastritis for which I was treated (about 45 days ago). I had floating stool at at that point of time. That subsided later on. But the past week I noticed that my stool.texture is very strange. There are tiny white things floating around. Last night I had some stomach pain in left mid section of my abdomen and today the stool looked more strange. It sort of looks like the food isn't properly digested. I have thyroid and hashimotos. I am consulting a doctor who had put me on vitamin b12, and vitamin d supplements, omega3 and carcumin. Should I be worried? Should I get my stool tested?
