Psoriasis, an autoimmune disorder, is a chronic skin condition characterized by inflamed, red, raised areas that often develop into silvery scales on the scalp, elbows, knees, and lower back. Psoriasis can also be asssociated with arthritis. It is estimated to affect 7.5 million people in the U.S.
The cause of psoriasis is unknown; however, it is thought to be caused by abnormally fast-growing and shedding skin cells. The skin cells multiply quickly, causing the skin to shed every three to four days. This may be caused by a trigger, such as injury, sunburn, certain classes of medications, infection, stress, alcohol, or tobacco. Though not contagious, the condition is hereditary. Psoriasis is often recurrent and occurs in varying severities.
The following are the most common symptoms of psoriasis. However, each individual may experience symptoms differently, as psoriasis comes in several forms and severities. Symptoms may include:
