Psoriatic arthritis is an inflammatory condition that affects the joints, tendons, and ligaments. It often occurs in people who have psoriasis, a chronic skin condition that causes red, scaly patches on the skin. People with psoriatic arthritis may experience joint pain, stiffness, swelling, and fatigue. Over time, the condition can cause serious damage to the joints and surrounding tissues.
What Causes Psoriatic Arthritis?
Psoriatic arthritis is thought to be caused by a combination of genetic and environmental factors. Scientists believe that people with certain genetic mutations are more likely to develop psoriatic arthritis. Additionally, certain environmental triggers, such as infection or injury, may cause the condition to develop or worsen.
What Are the Symptoms of Psoriatic Arthritis?
The symptoms of psoriatic arthritis vary from person to person. Common symptoms include joint pain, stiffness, swelling, and fatigue. Some people may also experience a fever, rash, and loss of appetite. In severe cases, psoriatic arthritis can cause deformities in the affected joints.
How Is Psoriatic Arthritis Diagnosed?
To diagnose psoriatic arthritis, a doctor will typically perform a physical exam and order blood tests to look for signs of inflammation. Other tests, such as X-rays and MRIs, can also be used to confirm a diagnosis.
How Is Psoriatic Arthritis Treated?
There is no cure for psoriatic arthritis, but there are treatments that can help control the symptoms. Nonsteroidal anti-inflammatory drugs (NSAIDs) and disease-modifying antirheumatic drugs (DMARDs) can help reduce inflammation and prevent joint damage. Physical therapy and lifestyle changes, such as maintaining a healthy weight and exercising regularly, can also help manage the symptoms of psoriatic arthritis.
