What causes rheumatoid arthritis?

- Genetics: Certain inherited genes may make you more likely to develop rheumatoid arthritis
- Environment: RA may be triggered by an infectious agent such as a bacteria or virus in an individual genetically predisposed
- Other factors: It is also thought that female hormones and the body’s response to stressful events may play a role
