Crohn's disease symptoms usually include abdominal pain and chronic diarrhea. Several other symptoms are possible, depending on the severity of the disease. Some people only have Crohn's disease symptoms now and then, while others have symptoms on a regular basis. Symptoms may also go away for months or even years if the disease goes into remission -- but they usually return at some point. If this happens, the person may even need to be hospitalized during severe flare-ups. Some Crohn's disease warning signs that you should report to your healthcare provider immediately include a fever, severe abdominal pain, and feeling groggy and disoriented.
