Rheumatoid arthritis is a painful condition because the very system that’s designed to protect your body is attacking it instead. Your body’s immune system is your first, and most important, a line of defense against potentially harmful diseases, foreign substances, bacteria, and more. Upon detection of something it deems hostile, your system kicks into gear and works to fight off and destroy the invader.
With rheumatoid arthritis, your body’s immune system, for reasons unknown, attacks the synovial fluid in your joints, causing chronic inflammation. Over time, this inflammation begins to affect the surrounding bone and tissue, compromising your joint’s ability to function correctly.
Medical researchers have been unable to pinpoint the cause of rheumatoid arthritis. The disorder typically strikes men and women between the ages of 30 and 60, but most people don’t start to see symptoms until they’re in their 60s.
While there’s no known cause of the disease, medical researchers believe the following may play a role:
- Genetics
- Environment
- Hormones
- Lifestyle risk factors, such as obesity and smoking
