Initially, many doctors may confuse the symptoms of Crohn’s disease with other conditions such as lactose intolerance, upset stomach, or irritable bowel syndrome. Over time, if these symptoms do not subside or grow worse, they may be a sign of a bigger problem.

Also, Crohn’s disease is a condition of constant ebbs and flows. Some months or weeks, the disease is in remission or has few symptoms. Then a relapse can occur, and symptoms return.

While considered a disease of the gastrointestinal tract, symptoms of Crohn’s disease are not limited to that. The disease can also affect the immune system responses and cause symptoms such as joint pain, skin rash, or eye lesions.
