The unfortunate truth is that we do not know nearly enough about what causes psoriasis and psoriatic arthritis. What we do know is that the likelihood of developing psoriasis is probably inherited but that an external factor—a trigger—may cause the disease to crop up. Doctors also believe that triggers can lead to flare-ups—those uncomfortable and downright painful periods of skin plaques, sore joints, fatigue, and/or other psoriasis symptoms.

So, what if you could potentially reduce your psoriasis flares by identifying your own personal triggers? Here’s everything we know about triggers, including strategies for discovering yours.

It would be great if there were known triggers that impacted everyone with psoriasis and psoriatic arthritis equally. If that were the reality, everyone with these conditions could simply avoid the same triggers to prevent psoriasis flares. But of course, it’s not so simple.
