Causes of Autoimmune Disease: A Summary
No one knows the exact cause or causes of
autoimmune diseases (autoimmune disorders). However, doctors do know that you cannot catch autoimmune diseases from another person.
Research on Autoimmune Disease Cause
Most autoimmune disease research scientists believe that there is a link between autoimmune diseases, a person's genes, and factors in the environment. Researchers believe that if you have a certain gene or combination of genes, you may be at higher risk for autoimmune disease but that you won't get the disease until something triggers your immune system. Triggers may include: the sun, infections, drugs, or pregnancy.
