Will being overweight increase my risk for psoriatic arthritis?

ANSWER

A recent study found that people who were overweight had a greater risk for psoriatic disease. Another study found that people who lost weight had less-severe psoriasis. Doctors aren’t sure why this is, but they do know that fat tissue releases proteins that cause swelling.
