The symptoms do overlap for all of these disorders. Most have vomiting and diarrhea and the appetite is variable. In advanced cancer or gastritis they are anorexic but early on can still have an appetite. An ultrasound is a good way to distinguish cancer and IBD from gastritis though. However IBD and cancer have thickened intestines and are hard to distinguish unless there is an intestinal biopsy obtained.
