Psoraisis Learning Zone


Read time: 10 mins

A number of conditions are associated with psoriasis, so effective management must take these into consideration. Psoriasis disease-related comorbidities include hypertension and cardiovascular diseases, obesity, type 2 diabetes, non-alcoholic fatty liver disease, anxiety, depression, and inflammatory bowel disease.


Are comorbidities actually part of the systemic disease? Find out more from Professor Ulrich Mrowietz.

This section of the Psoriasis Learning Zone will provide an overview of some of the comorbidities associated with psoriasis, their impact on mortality and address the link between psoriatic arthritis and comorbidities.
