A study released in 2012 showed that people with psoriasis are twice as likely to develop type 2 diabetes as people without the condition. Researchers analyzed 27 different studies and all but one of them found a link between psoriasis and diabetes type 2.
High blood pressure
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.
One study looked at more than 6,500 people and found that of those with psoriasis, 63 percent had abdominal stomach obesity and 44 percent had high triglyceride levels. According to the study, only 13 percent of people with psoriasis did not show any evidence of metabolic syndrome.
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.
