Psoriatic Arthritis and Psoriasis: What's the Connection?
Psoriasis and Psoriatic Arthritis Triggers
So far, scientists have not been able to identify psoriatic arthritis
triggers. Currently, it's not possible to predict which people with psoriasis
will go on to develop psoriatic arthritis.
Researchers have been able to determine a number of triggers for psoriasis,
- Stress: For some people, stress can cause psoriasis flare-ups.
- Some medications: Certain medications, including lithium and medications
used to treat malaria, can make existing skin lesions worse or prompt a
- Strep infection: For some people with psoriasis, strep throat infection is
believed to lead to guttate psoriasis, a form of the disease that causes red
spots to form on the skin.
- Lack of ultraviolet light: Winter's long, dreary days can also make
psoriasis symptoms worse, since the sun's ultraviolet light helps clear skin
plaques and lesions for many people.
- Skin injury: Trauma to the skin, such as insect bites, sunburn or
scratches, can be a trigger for psoriasis to appear (known as a Koebner
Some research studies suggest that people with more severe psoriasis may be
more likely to develop psoriatic arthritis, but so far there's no certain
proof. However, a possible link means it is important to treat psoriasis skin
lesions as soon as they occur.
Even though psoriatic arthritis triggers are largely a mystery, there are
steps you can take to maximize your health and minimize the impact of psoriatic
Making sure you get enough rest and exercise and eating a healthy, varied
diet can help strengthen your immune system, muscles, and joints -- all of
which are key players in the battle against psoriatic arthritis. Experts also
recommend using stress-reduction techniques to help cope with stress, which can
worsen psoriasis and potentially psoriatic arthritis.
