How do my other medical conditions affect, or are they affected by, my psoriasis?
Psoriasis has been shown to be a systemic inflammatory condition with similarities to other inflammatory immune disorders. In addition to its effects on the skin, 30 percent of people with psoriasis will also have psoriatic arthritis.
Besides its association with arthritis, psoriasis is associated with depression, obesity, and atherosclerosis (a buildup of plaque in the arteries). Those with psoriasis may also have an increased prevalence of ischemic heart disease, cerebrovascular disease, peripheral artery disease, and an increased risk of death.
Inflammation could be a biologically plausible explanation for the association between psoriasis and high blood pressure or hypertension, as well as that between psoriasis and diabetes. Research and attention has also been focused on the association between psoriasis, cardiovascular health, and heart attacks or myocardial infarction.
