Getting Under The Skin: What Is Psoriasis?

Psoriasis is a chronic skin disorder for which there is no cure.

Other symptoms include joint pain and thick, pitted nails. The disease can be quite debilitating and can cause considerable emotional distress.

What is psoriasis?

Psoriasis is a chronic skin condition which is caused by a disorder of the immune system. It speeds up the growth cycle of skin cells and causes them to build up rapidly on the skin’s surface. There they form red patches which are flaky, and itchy, and sometimes painful. The exact cause of psoriasis is unknown.

Psoriasis in an immune system disorder. Psoriasis causes the body’s T cells, white blood cells, to over-react. This response leads to the over-production of skin cells and inflammation. Although there is no cure, treatment outcomes for managing symptoms are quite positive, though patients do tend to have flare-ups which may be caused by diet, stress or ill health. Flare-ups are also sometimes seasonal.

Scratching the itch: triggers and treatments for psoriasis

psoriasis flare-up typically starts or gets worse because of a trigger which you may not be aware of, or you may not be able to avoid. Triggers can include a skin infection or injury to the skin, strep throat, a bug bite, sunburn, smoking, stress, heavy alcohol consumption. It may also be triggered by medications such as beta blockers, lithium, or antimalarial drugs.
