There are several risk factors for psoriatic arthritis. Having skin psoriasis is an important factor. It is still unclear why only few people with psoriasis get arthritis. Being overweight and widespread skin psoriasis are some of the risk factor for arthritis. Stress, trauma to the skin or a joint, and infections are considered as some of the other triggers. If you have a first degree relative, a parent, or a sibling with psoriatic arthritis, you are at higher risk of having this disease. Maintaining a healthy weight could help minimize joint pain symptoms. Following a healthy diet and an anti-inflammatory diet could also help reduce some of the symptoms.
