Psoriasis is a chronic inflammatory immune disease that can occur in a wide variety: there can be some barely noticeable patches on skin, but it can also occur all over the body. Most often, it can occur on the scalp, knees and elbows. The classic psoriasis lesion is sharply outlined, reddened, slightly raised from the surrounding skin, and scaly. Skin lesions are often accompanied with nail damage. Inflammation of joints occurs in a third of the patients (psoriatic arthritis).
Psoriasis is mostly diagnosed clinically and no extra tests are required. In some cases, if the symptoms are more atypical it is necessary to take a skin biopsy.
Psoriasis treatment is done in steps, meaning that it is started by using the more common topical medications (creams, skin solutions, etc.). With widespread skin lesions or joint problems, systemic treatment is needed (tablets, UVB light treatment, biological injections). In addition to specific treatment, it is recommended to treat any chronic inflammations, like broken teeth, antritis or quinsy, lose any excess weight, give up smoking and stop alcohol abuse. Studies show that these lifestyle changes can ease the disease and facilitate the treatment notably.
