I have been having a combo of constipation and diarrhea/loose stools (more often than not) for weeks now. I am taking Align and fiber, and nothing really seems to help. I stopped eating dairy, drinking only Lactaid, was tested for celiac, and it came back negative. I have a lot of gas, stomach pains, just generally feeling badly. Day to day, I never know how I am going to feel, whether if I what I eat will make my stomach upset, it is exhausting. I am wondering if I just have basic IBS (by suggestion of my primary doc) or if there is something else going on with me... could it be sensitivity to some foods possibly? I have struggled with this on and off for most of my adult life (I am 32 now) and just want to figure out what is going on. I am so tired of living like this. Any suggestions?
