Psoriasis is a long-lasting skin disease. Patches of skin become scaly and inflamed.
Psoriasis usually affects the scalp, elbows, and knees. But it can also appear on other parts of the body.
Anyone can develop psoriasis. It arises when the body’s disease defense system becomes overactive. This triggers skin cells to multiply too fast.
Symptoms can vary based on the type of psoriasis. Some people develop thick patches of red skin with silvery-white scales. Others have dry, cracked skin or thick, uneven nails. Symptoms can flare up for a few weeks or months before easing.
The underlying cause of psoriasis is not fully understood. But genes and the environment likely play a role. Many affected people have a family history of the disease. Infections, smoking, certain medicines, and obesity can increase the chances of psoriasis.
Treatment depends on the type of psoriasis. For mild psoriasis, ointments and creams often help. For moderate to severe psoriasis, doctors may prescribe pills or injections. Some doctors recommend phototherapy for large affected areas. This involves shining ultraviolet light on distressed skin.
Psoriasis can greatly affect your daily life. But you can take steps to control symptoms. Managing triggers like stress and avoiding skin injuries can help.
