A. How much do you know about psoriasis prevention and treatment? Psoriasis (commonly known as psoriasis) is a chronic recurrent inflammatory skin disease with an incidence rate of 0.1%-3%. With environmental pollution and changes in dietary structure, there has been a significant growth trend in recent years (experts estimate that there are no less than 5 million psoriasis patients in China), and the age of first onset has decreased significantly. Because patients are influenced by negative propaganda, “talk about ringworm” and “avoid ringworm psychology” are common, which largely drive patients to blindly treat the disease, leading to gradual aggravation and the gradual increase of serious types of psoriasis, which seriously affects the quality of life of patients. Therefore, it is especially important to correctly perceive, eliminate misconceptions and guide psoriasis patients to take individualized treatment plans. 1, psoriasis is not an incurable disease: psoriasis due to recurrent attacks, so that patients believe that it can not be cured, but in fact it is not. The psoriasis that is feared in the crowd is only a part of the patients who have recurrent attacks, and there are some patients whose condition is stationary or completely receding. In fact, like the flu and gastritis, it is easy to recur, but with our current medical technology is fully capable of controlling the clinical symptoms of psoriasis. 2, psoriasis is not just a disease of the skin: In recent years, the number of cases of psoriasis patients with metabolic diseases (central obesity, hypertension, hyperlipidemia, diabetes) due to poor lifestyle has been increasing. The interaction of these metabolic syndromes with psoriasis increases the difficulty of treating psoriasis, so other comorbidities must be taken into account when treating psoriasis, and more importantly, the treatment of psoriasis should avoid leading to other diseases. Patients are advised to always go to the dermatology department for comprehensive consultation and treatment. 3, psoriasis is not unpreventable: the occurrence of psoriasis is influenced by multiple factors such as genes and internal and external environment, so for healthy people or patients with family history, if the factors of internal and external environment are eliminated (improving immunity, less infection, adjusting dietary structure, etc.), recurrence can also be controlled or reduced. 4, psoriasis is not contagious: psoriasis repeated flaking, intuitive and embarrassing lesions, so that people “daunted”, many patients and even family and friends worry that it will be contagious, so that patients isolated, even anxiety, depression, reducing social activities. This is very wrong, psoriasis lesions are caused by the excessive proliferation of epidermis, not bacterial, will not be contagious, the understanding and support of patients’ families and friends will increase the patient’s confidence in healing, which is beneficial to the recovery of the disease. 5, psoriasis can not be blindly overzealous treatment: many patients believe that the treatment of psoriasis needs to “fight poison with poison”, and seek medical help in a hurry, mistakenly believing that the symptoms can be eliminated with toxic, and even some psoriasis patients superstitiously believe in charlatan doctors. These are not scientific, many drugs can cause other diseases or aggravate the original disease, and certain Chinese medicines can cause accumulation or poisoning in the body, which may cause long-term harm. Therefore, psoriasis patients must use drugs under the guidance of dermatologists. Do not blindly seek new drugs and elixirs, many new drugs may finally exit the historical stage by eliminating them after years of clinical experience.
