Other health conditions may increase your risk of developing PsA. Research suggests that people with psoriasis who have one or more of the other health conditions below are more likely to develop PsA.
Obesity
According to Eric Ruderman, MD, a rheumatologist and a professor of medicine in the division of rheumatology at Northwestern University Feinberg School of Medicine in Chicago, “There is no question there is a link between obesity and psoriasis, and that there is a higher risk in those with obesity of developing psoriatic arthritis on top of psoriasis.”
Dr. Ruderman adds that “diet is not one-size-fits-all” but recommends limiting processed foods and excess sugar and aiming for a balanced diet with lots of vegetables.
“If you believe that specific foods may trigger your psoriatic arthritis symptoms, it may be reasonable to avoid those foods for two to four weeks to see if your symptoms improve, but there are no particular foods that we generally recommend avoiding if you have psoriatic arthritis,” Ruderman says.
Musculoskeletal Conditions
People with psoriasis who have nonspecific musculoskeletal symptoms, such as joint pain, fatigue, and stiffness, often go on to develop PsA. The link is unclear. Rather than being a cause, these could be early symptoms of PsA.
If you have psoriasis, taking measures to avoid traumatic injuries and overuse could help delay or prevent PsA.
Depression and Anxiety
Seeking treatment for depression, anxiety, and other mood disorders may improve your quality of life with psoriasis and lower your PsA risk.
