Reactive arthritis is an autoimmune disorder that can cause joint pain, swelling, and stiffness. It is a form of arthritis that is triggered by an infection in another part of the body. While the exact cause of reactive arthritis is not known, it is believed to be an immune system response to an infection.
The most common type of infection that can lead to reactive arthritis is a bacterial infection, such as a urinary tract infection (UTI), sexually transmitted infection (STI), or gastrointestinal infection. In some cases, a virus or fungus may also be the cause.
Can Reactive Arthritis Spread?
Reactive arthritis is not contagious, so it cannot be spread from person to person. However, the infection that triggers the condition can be spread from person to person. For example, if you have a UTI, you can pass it to your partner through unprotected sexual contact.
Immune System
Reactive arthritis is thought to be caused by an overactive immune system response to an infection. When the body's immune system overreacts to an infection, it can cause inflammation and pain in the joints. This inflammation can lead to joint damage and disability over time.
Treatment
Treatment for reactive arthritis typically involves antibiotics to treat the underlying infection. Additionally, medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and disease-modifying antirheumatic drugs (DMARDs) may be prescribed to reduce inflammation and pain. Physical therapy and rest can also help improve joint function and mobility.
