Anyone who has psoriasis knows just how uncomfortable it can be. The skin condition, which is actually an autoimmune disease, occurs when skin cells grow and appear on the outer surface of the skin at an accelerated rate. The result? Raised patches of dry red, white, or silvery skin that can feel itchy or even painful.

What most people dont realize is that there are five different forms of the chronic disease, the most common of which is called plaque psoriasis. But what actually causes the uncomfortable condition? While its not entirely clear, its possible that a family history of the disease, as well as lifestyle factors like smoking and obesity, can raise ones risk of psoriasis.

While you may not be able to do anything about your familys genetics, you can certainly take smart steps to stay healthy and lower your risk of psoriasis. For one, ditch your cigarette habit stat. Next, eat the right kinds of foods to keep your body at a healthy weight.
