What is Crohn's Disease?

Crohn's disease is a disease of the digestive tract. It causes inflammation of the lining of your digestive tract, a very painful occurrence. It also causes severe diarrhea which can lead to malnutrition. It is believed to be connected with the body's immune system.

Unfortunately when you have this disease your immune system can't tell the difference between normal body tissue and foreign tissue. This causes and overactive response from your immune system that leads to chronic inflammation which is known as an autoimmune disorder.

What Causes Crohn's Disease?

There are many theories about what causes crohn's disease. After much study scientist seem to universally believe that it is caused by three basic factors: immune system problems, genetics and environmental factors or infections.

Immune System Problems

Normally the immune system is quite capable of telling the harmful microbes from the helpful microbes. People with Crohn's Disease have an immune system that can't tell one microbe from another. Soooo...their immune system attacks every microbes, even the one's that are there to help. Because the immune system is so busy attacking everything the digestive system becomes inflamed and is unable to stop being inflamed because the immune system can't stop attacking. It becomes a vicious cycle. This chronic inflammation eventually causes ulcers and other injuries to the intestines.


It is believed that genetics plays a role in Crohn's Disease. Between 10 to 20% of the people with this disease have other family members with the disease.

Infections (Environmental Factors)

At one time it was believed that measles increased the risk of developing Cronh's Disease. Since the development and use of the measles, mumps, and rubella vaccine it has been refuted by many studies.
