Common Crohn's disease symptoms can include abdominal pain (or stomach pain), recurring diarrhea (four to six times a day), and weight loss. However, other symptoms are possible, depending on the severity of the disease. What's more, some people experience Crohn's disease symptoms only once in a while; others, however, have symptoms on a more regular basis. Symptoms of Crohn's disease may go away for months or even years if the disease goes into remission -- but they usually return at some point.
