For people with psoriatic arthritis, fatigue is more than just an energy drain after a long day at work. It’s a serious symptom that can affect quality of life. You and your doctor may have to work to find its exact cause and decide how to treat it.
Psoriatic arthritis is a disease where your body makes proteins, called cytokines, that cause inflammation. This makes your joints swell and become painful or stiff.
These proteins may also cause fatigue, although doctors aren’t sure why. One thought is that when your psoriatic arthritis flares up, the cytokines trigger your immune system to go haywire. Instead of making chemicals to fight infection, it attacks your joints. Fatigue may be a result of your body using its energy for this process.
A healthy lifestyle can help you handle fatigue. When you have psoriatic arthritis, it’s important to manage your weight, stay active, avoid smoking, and take your medications. When your inflammation is out of control, you may feel more tired.
