Psoriatic Arthritis
Moderate
Psoriatic arthritis is an inflammatory form of arthritis associated with psoriasis, a condition that affects the skin and may also affect the nails. It can cause pain, stiffness, swelling, and reduced movement in affected joints. The disease may involve different joints and can affect the fingers, toes, spine, or other areas. Symptoms may vary over time, with periods of increased inflammation and periods of fewer symptoms.

When to Seek Medical Attention
Psoriatic arthritis requires medical assessment and ongoing treatment because persistent inflammation can damage joints and affect function. Seek prompt care for worsening joint swelling, pain, stiffness, or reduced mobility. Urgent evaluation is appropriate for a suddenly hot and severely swollen joint, significant eye pain or redness, severe systemic symptoms, or sudden neurological or breathing problems.

Causes 2
Psoriatic arthritis is related to abnormal activity of the immune system, which causes inflammation in the joints and surrounding tissues. The exact reason this immune response develops is not fully understood. Genetic susceptibility may contribute, and environmental or other triggers may influence the development of the condition. Psoriatic arthritis can occur in people with psoriasis, although the severity of skin disease does not always correspond to the severity of joint symptoms.
Autoimmune Disorder
Genetics
Risk Factors
Having psoriasis is an important risk factor for psoriatic arthritis. A family history of psoriasis or psoriatic arthritis may increase susceptibility because genetic factors can influence the immune response. Other autoimmune or inflammatory conditions may also be associated with increased risk. People with psoriasis who develop persistent joint pain, swelling, stiffness, or changes in movement should discuss these symptoms with a healthcare professional.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis of psoriatic arthritis is based on the pattern of joint symptoms, physical examination, medical history, and evidence of psoriasis or related skin and nail changes. Imaging studies such as X-rays, ultrasound, or magnetic resonance imaging may help identify inflammation and joint damage. Blood tests can help evaluate inflammation and may be used to help distinguish psoriatic arthritis from other types of arthritis. There is no single test that independently confirms every case.
Prevention
Key Prevention Tips
Psoriatic arthritis cannot always be prevented because its exact cause is not fully understood
Managing psoriasis and maintaining regular medical care may help identify joint symptoms at an early stage
Regular physical activity can help maintain joint movement and general fitness, while maintaining a healthy weight may reduce stress on weight-bearing joints
Protecting the joints from unnecessary injury and seeking medical evaluation for persistent pain, swelling, or stiffness can support early management
Prevention Guidance
