Psoriatic Arthritis is a chronic (long-term) autoimmune disease. Normally, the immune system fights infections, but in autoimmune diseases, it attacks a person’s own body. In psoriatic arthritis, the immune system causes damage to the joints and areas where the muscles and cartilage connect to bones (called tendons and ligaments)
According to the National Psoriasis Foundation (NPF), up to 30 percent of people with psoriasis will develop psoriatic arthritis.
PsA, which is an inflammatory form of arthritis, affects an estimated 2.25 million Americans.*
Some symptoms of psoriatic arthritis are always present, while others appear at specific times (called “flares”).
Symptoms of psoriatic arthritis may include:
Genetics play a role in developing psoriatic arthritis. 2 out of 5 people with psoriatic arthritis have a family member with psoriasis or psoriatic arthritis. However, you may have no family history of psoriatic arthritis and still develop it.
Your environment or lifestyle could also increase your risk. Obesity, stress, infection, and injury can increase your chance of psoriatic arthritis.
