Crohn Disease FAQs (cont.)

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.

Who gets Crohn's disease?

Anyone can get Crohn's disease. Crohn's disease affects all ages and all social and ethnic groups. Crohn's disease most often strikes young adults aged 15 to 30 years, but it can also appear in young children, middle-aged, and elderly people.
