Psoriasis is an autoimmune illness that manifests in a flaky, thick, red, and itchy skin. Patches on the skin brought about by the disease crust over with a covering of silver scales. The immune system uses cells known as T cells to fight off infections. In doing so, they produce inflammation-causing chemicals. When this process goes wrong, it leads to an abnormal growth of skin cells and inflammation with this illness. The severity of psoriasis symptoms differs from individual to individual and the form of the disease. It may infect any part of the body, although it is most common on the scalp, knees, elbows, and lower back. An attack of this disease can be categorized as mild, moderate, or severe. So, what causes psoriasis? Well, several factors can predispose one to get the disease while others can trigger a flare-up. They are highlighted in detail below.
