Causes of Rheumatoid Arthritis
RA is caused by a combination of genetic and environmental factors that trigger an abnormal immune response. Possible causes:
- Genetic factors-Certain genes that play a role in the immune system are associated with RA development.
- Defects in the immune system can cause ongoing inflammation.
- Environmental factors-Certain infectious agents, such as some viruses or bacteria, may increase susceptibility to RA.
- Other factors-Some evidence suggests that hormonal factors may promote RA development in combination with genetic factors and environmental exposure.
