The prognosis of psoriasis is good. According to the analysis of clinical statistics, although psoriasis has the tendency of chronic prolongation and recurrent attacks, most of them do not have serious consequences. As long as the treatment is handled properly, the general rule is that the number of recurrences gradually decreases with age and prolongation of the course of the disease, the remission period in which the disease is stably controlled gradually lengthens, and the recurrence of the disease is gradually reduced. Even arthritic psoriasis, pustular psoriasis and erythrodermic psoriasis, which have more severe symptoms, will be well controlled with reasonable and effective treatment of the skin and other symptoms. Only a very small number of patients have progressive exacerbations and are insensitive to conventional drug responses, a condition for which some high-tech therapies have also shown good promise. Most of the cases that we encounter in clinical medical treatment that are very difficult to treat or affect the health of the whole body, as well as the rare occurrence of serious complications or even death, are due to irregular treatment or visits to irregular clinics, abuse of corticosteroids, immunosuppressants or anti-tumor drugs, etc. Therefore, as a psoriasis patient, we should understand that psoriasis is a benign disease that does not pose any major health problems and has a good prognosis as long as it is handled correctly. In the course of life and medical treatment, you must avoid those harmful behaviors so that your physical and mental health is always in an atmosphere of virtuous circle.
