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.
