question: my current symptoms are: low grade fever, nausea, vomiting, diarrhea, bloating, abdominal pain, rapid weight gain, acid reflux type symptoms, and hair loss. I would consider these symptoms chronic because I have had them for about a year off and on. Are these symptoms indicative of an ulcer? Are they indicative of ibs? What route would you take in order to diagnose my condition? I have had a colonoscopy, stool sample, and blood work--all with normal results. One doctor thought that I might need an endoscopy. What should I do?
