There are a number of conditions that can mimic Crohn's disease. In certain parts of the world tuberculosis is very prevalent and it can mimic symptoms of Crohn's disease. There are other conditions that are inflammatory diseases of the bowel, such as microscopic colitis that can cause symptoms that may be similar to Crohn's disease, such as abdominal pain or diarrhea. Celiac disease is another condition that can present with similar symptoms, namely weight loss, diarrhea, abdominal pain.
