What is it?

What is reactive arthritis? 

Reactive arthritis is pain or swelling in a joint that is caused by an infection in your body. You may also have red, swollen eyes and a swollen urinary tract. These symptoms may occur alone, together, or not at all.

Most people with reactive arthritis recover fully from the first flare of symptoms and can return to regular activities two to six months later. Some people will have long-term, mild arthritis. A few patients will have long-term, severe arthritis that is difficult to control with treatment and may cause joint damage.

What causes it?

What causes reactive arthritis?

Reactive arthritis may be set off by an infection in the bladder or the urethra, which carries urine out of the body. In women, an infection in the vagina can spark the reaction. For both men and women, it can start with bacteria passed on during sex. Another form of reactive arthritis starts with eating food or handling something that has bacteria on it.

You can’t pass your reactive arthritis on to someone else. However, you can pass along the bacteria that can trigger the disease.

Doctors do not know why some people develop reactive arthritis and others do not.
