What is rheumatoid arthritis?

Rheumatoid arthritis is a condition that can cause pain, swelling and stiffness in joints.

It is what is known as an auto-immune condition. This means that the immune system, which is the body’s natural self-defence system, gets confused and starts to attack your body’s healthy tissues. In rheumatoid arthritis, the main way it does this is with inflammation in your joints. If you have RA, you're not alone. It affects around 400,000 adults aged 16 and over in the UK.
