Lots of things!: Your symptoms are non-specific but fatigue is concerning. Gi-related problems can originate from the small intestine (crohn's, infection, partial obstruction), the colon (colitis, appendicitis, tb, altered motility), the kidney &collecting system (ascending infection, stones), ovaries, tubes, uterus, hernias that may contain bowel, bleeding, abscess...You get the point. Please seek evaluation.
