Summary

The association between psoriasis and alcohol consumption is complex. Epidemiological evidence suggests that patients with moderate to severe psoriasis have an increased incidence of alcohol-related diseases and mortality. This appears to be unique to psoriasis compared with other autoimmune diseases. Excessive alcohol consumption may contribute to systemic inflammation and the comorbidities associated with psoriasis, including cardiovascular disease and depression. Screening for hazardous alcohol consumption and appropriate interventions may be useful in patients with moderate to severe psoriasis.
