What causes Crohn's disease?
We do not know what causes the abnormal inflammation in the digestive tract. Experts believe that it is caused by an unknown triggering event in susceptible people. We do not know what makes a person susceptible, except that about 20% to 30% of people with Crohn's disease have relatives with the disease - in other words, Crohn's disease runs in the family. In the other 70% to 80% of cases, there is no family connection. There is no evidence that stress or diet causes Crohn's disease - although these factors can make the symptoms worse.
