Causes of psoriasis
First, genetic factors. At present, psoriasis has genetic tendency. About 20% of psoriasis has family history. When the parents have psoriasis, the incidence rate of psoriasis is 16%, while the incidence rate of psoriasis among parents is 50%.
Second, infection factors. Some people think that it is caused by virus infection. Although eosinophilic inclusions have been found in the nucleus of epidermal spinous cells, the virus culture has not been successful so far. Streptococcal infection may be an important predisposing factor of the disease, because acute tonsillitis or upper respiratory tract infection often occurs before the eruption of acute guttate psoriasis.
Third: metabolic disorders. There are reports of patients with increased serum lipids, cholesterol, globulin, sugar, uric acid, potassium, and decreased folic acid content, but no definite conclusion can be made. The increase of polyamines and arachidonic acid in the lesions has also been reported.

Psoriasis patients should not be exposed to intense ultraviolet radiation. The prevalence of psoriasis in areas with serious environmental pollution is significantly higher than that in other areas. Many patients are caused by long-term working or living in high temperature, humidity, cold and other environments.
