Psoriasis does not affect life expectancy, but because it is stubborn, it can seriously affect the patient’s psychology and physiology, and have an impact on the quality of life. Psoriasis is a common skin disease, the cause of which may be related to genetic factors, immune factors and so on. Psoriasis does not affect life expectancy, but due to the obvious itching symptoms and skin lesions, it leads to a lower quality of life and affects the physical and psychological health of patients. Psoriasis manifests itself in the form of red plaques on the extensor sides of the limbs, scalp and other parts of the body, which will be accompanied by silvery-white scales on the surface of the plaques, with symptoms such as itching, pain, dry skin and even bleeding. It should be treated with medicines such as topical carbotriol ointment and tazarotene gel as prescribed by the doctor, and if necessary, use medicines such as Avicenna and azathioprine to treat the disease. In order to consider the health of psoriasis patients, it is recommended that patients consult a doctor in time, strictly follow the doctor’s instructions for treatment, and try to improve the quality of life.
