    Frequently Asked QuestionsPsoriatic Arthritis

    Is there a PsA diet?

    There is no one specific diet for PsA. However, it is recommended that if you are overweight, a reduced-calorie diet can help you feel better. A gluten-free diet is recommended if you have tested positive for gluten sensitivity. Vitamin D supplementation may be helpful, but more research is needed. There are foods that are have been known to be pro-inflammatory such as fried foods and those with excess sugar, so it may be best to avoid ‘em (good advice for everyone).

    How is PsA different from RA?

    Most people with psoriatic arthritis will also have psoriasis—that’s not typical with rheumatoid arthritis. Psoriatic arthritis usually shows up in only one joint, like one knee, whereas RA typically affects both. It’s symmetrical like that. Dactylitis, the swelling of a finger or toe, is also more common in PsA compared to RA. There is no blood test for PsA, but if you have RA, it can often be detected by blood work.

    What triggers a PsA flare-up?

    Some triggers can be individual, like missing a good night’s sleep or working too hard, but one universal is stress—either the physical kind that occurs with a blow to the knee or a virus, or emotional angst, such as the type accompanying a big life transition.

    Are there any supplements that can help PsA?

    There is some promising research about omega-3 supplements and vitamin D, but more studies are needed, per the National Psoriasis Foundation. Glucosamine and chondroitin are often touted as helping with arthritis, but all the studies have been done in osteoarthritis, not psoriatic arthritis. Always check with your doctor before taking any over-the-counter vitamin or supplement, since it may interact with your Rx medications.
