For the past month I've been feeling really weak and have had diarrhea. The diarrhea comes and goes and the weakness stays forever. I sleep a good amount of time as I always have my routine is the same as always, The only difference is that I recently graduated and for the moment unemployed (not doing much lately). I know that diarrhea Causes fatigue but like I said, don't always have it but I do have the weakness every time I wake up and for the rest of the day. Does anyone have an idea of what this might be?
