Causes: –Genetics - genes that you inherit from your parents may increase your risk of developing Crohn’s disease (genetic susceptibility). –The immune system - it appears that the immune system is responsible for the inflammation that occurs in Crohn’s disease. –Previous infection - a previous bacterial, or viral, infection may trigger an abnormal response from the immune system. –Environmental factors - the fact that Crohn’s disease is most common in ‘westernised’ countries, such as the UK, and least common in poorer parts of the world, such as Africa, may be due to environmental factors.
