L40.0: Psoriasis vulgaris
Your body’s own immune system plays a role in the development of psoriasis. The condition can be hereditary. Other family members may then be affected, too. Triggers such as skin irritations, stress or certain medications can make the condition worse.
Psoriasis typically results in skin changes. Excessive amounts of new skin cells are formed in the changed areas. The skin also becomes inflamed. The areas affected then become red and are very scaly. The skin typically changes in particular on the elbows, knees and the tailbone. The skin may itch and crack. The nails may also change.
