Several studies have linked psoriasis with high blood pressure (hypertension). The World Health Organization (WHO) recently recommended that health care professionals “routinely scan" patients for hypertension, which increases the risk for a number of serious health problems.
Around 10 percent of patients with psoriasis also develop psoriatic arthritis. In severe cases of psoriasis, this percentage increases even higher. Arthritis is three to four times more common in people with the chronic skin condition than in those without psoriasis. Usually psoriasis develops before psoriatic arthritis.
According to Medical News Today, severe psoriasis has been linked to an increased risk for heart attack. Additionally, risks associated with obesity also can contribute to cardiovascular disease -- putting overweight or obese people with psoriasis at even higher risk for developing heart disease.
In addition to an increased risk for a number of serious physical illnesses, people who have psoriasis also have a higher likelihood of developing depression and anxiety, and an increased risk for suicidal thoughts. Studies have shown that the more severe the psoriasis symptoms are, the higher the risk for developing depression or anxiety is.
