Nonalcoholic Fatty liver disease and psoriasis: what a dermatologist needs to know

Psoriasis is a systemic inflammatory disease associated with a variety of comorbidities.

Patients with nonalcoholic fatty liver disease and psoriasis have more severe skin disease and are at higher risk of severe liver fibrosis than patients without psoriasis. The authors will review the diagnosis of nonalcoholic fatty liver disease and also discuss lifestyle changes and treatments for psoriasis that may benefit or worsen nonalcoholic fatty liver disease.
