Environment
Crohn’s disease is more common in urban areas and industrialized countries. Also, those people who are living in northern climates tend to be at a higher risk of the condition. This indicates that many environmental factors might play a key role. These include stressors of the modern life, polluted air and water, virus and bacteria, and many other elements that can lead to an abnormal response of your immune system. Some studies also show that when specific genes in the body interact with some factors in the environment, the likeliness for developing this condition also goes up. [4]
