Psoriasis is a chronic inflammatory skin condition which causes thick red scaly rashes, often on the scalp, elbows, knees, body and face. Sometimes, psoriasis can also cause unsightly thickened nails, and painful joint inflammation.
Because of the persistence of these thick rashes, psoriasis can cause significant distress and embarrassment, and also affects quality of life. Both genetic and environmental factors are understood to play a role in the development of psoriasis. Common triggers can include stress, alcohol, smoking, infections and certain medication.
Psoriasis is now known to be not just a skin condition, but with significant association with underlying diabetes, hypertension and high lipid level. It is therefore important to recommend annual health screening for people with psoriasis.
