Yes I started losing weight back in Jan and wasn t trying to .then about mar I started loosing my appetite.eat little fill full.and I kept on loosing we right know I m getting nausia and hurting below my breast bone and hurting about my belly button.so I finally went to the Dr.and he is sending me to a gastrologist.but since then I have been pooping yellow.and I was wondering g if it could be the milk of magnesia causing the yellow poop I have always used this and it has never done this.
