From osteoarthritis to heart disease to diabetes, obesity is implicated in a host of diseases. A study now adds one more condition to the list: psoriatic arthritis, or PsA.
Psoriatic arthritis, an autoimmune condition, is a form of inflammatory arthritis that affects an estimated 6 to 10 percent of people with of the skin condition psoriasis and up to 40 percent of those with extensive psoriasis. It can also affect people who do not have the skin disease.
It’s been known that being overweight or obese increases a person’s chances of developing psoriasis. But a study in the Annals of the Rheumatic Diseases, researchers report a link between body mass index, or BMI, and psoriatic arthritis, too.
