1. To correctly recognize psoriasis. Psoriasis is not a contagious disease, the disease patients will not transmit the disease to others. However, a part of the patients with the disease (about 1/3) have genetic factors. Through effective treatment, psoriasis can be relieved or will not recur for a longer period of time, but it cannot be completely cured yet. 2. Psoriasis patients should keep a good state of mind and should actively cooperate with doctors for treatment. Research shows that a good state of mind has a good regulating effect on the secretion of neuromediators as well as the function of endocrine system and immune system. Mental trauma, high tension, heavy thought burden, psychological imbalance and other factors may induce or aggravate psoriasis.3. Choose medicine reasonably. Psoriasis patients must choose drugs for treatment according to their disease type, diseased parts and whether they are combined with other diseases, etc. Meanwhile, they should follow the doctor's instructions, have regular checkups and insist on treatment. If abnormal reaction occurs in the course of treatment, it should never be treated by oneself and should go to the hospital as soon as possible for treatment. There are many methods and medicines for treating psoriasis, and there are cases that are cured and not cured in different places, so patients should seek medical treatment reasonably according to the local medical conditions and combine with their own specific conditions, and do not seek medical treatment blindly.4. Don't take a hot water bath. Psoriasis patients should avoid bathing in hot water and being irradiated by ultraviolet rays in the progressing period of the disease, and should not use irritating topical medicines, so as not to induce erythrodermic psoriasis. In the stable and regressive stages of the disease, patients can use warm water with soap to soak and wash the lesions to remove the scales. The concentration of topical medication used should also be gradually transitioned from low to high, and applied to a small area first, and then expanded if there is no strong reaction. In order to improve the efficacy of treatment, patients with this disease can also be treated with localized sealing method. If the patient's lesions are more extensive, the use of topical drugs should also avoid toxic reactions caused by over-absorption of topical drugs.5. Symptomatic treatment should be carried out according to different triggering factors. For example, psoriasis induced by streptococcal pharyngitis can be controlled by antimicrobials; psoriasis induced by immune dysfunction can be treated with drugs to regulate immune function; psoriasis induced by psychiatric factors can be treated with sedative and antidepressant drugs, or through psychological counseling; psoriasis with extensive lesions and serious condition should be treated with topical medicines based on systemic therapy; psoriasis with limited lesions should be treated with systemic therapy; psoriasis with limited lesions should be treated with topical medicines based on systemic therapy. Psoriasis with limited skin lesions can be treated with topical drugs alone. 6. To prevent or reduce the recurrence of the disease. Psoriasis patients should not stop the treatment immediately after the skin lesions subside or reach the standard of clinical cure, but continue the treatment for 1~2 months, and should have preventive treatment for 1~2 months when the season of psoriasis is easy to flare up. 7. Pay attention to dietary contraindications. The skin lesions of psoriasis patients will have a lot of scales falling off, which will inevitably consume a lot of protein, vitamins, trace elements and other nutrients in their bodies. If these consumed nutrients can not be supplemented in time, it will cause various nutrient deficiencies in the long run, which can damage the health. Therefore, psoriasis patients should eat more eggs, fresh fruits and vegetables, soy products, dairy products and other foods rich in the above nutrients, but to avoid high-fat and high-sugar diet, eat less pork, beef and mutton. In addition, patients with the disease should also stay away from strong alcohol, tobacco, tea, coffee and spicy food.
