Psoriasis, commonly known as psoriasis, is a chronic inflammatory skin disease that often manifests itself in the form of erythema, plaques, papules, and large amounts of white scales. Because it is often recurring and difficult to cure, it is known as an immortal cancer of the skin, affecting the physical and mental health of patients. Various questions about psoriasis will be answered for you below. What are the causes of psoriasis? The causes of psoriasis are still being painstakingly explored, and the specific initial triggers of psoriasis are still unknown. The results of current research suggest that it is caused by skin immune dysfunction in the context of a specific genetic background and after the effects of the acquired and external environment. How to correctly recognize and treat psoriasis? For most psoriasis patients, the impact on psychology and life is far greater than the impact on physical health, so it is very important to correctly recognize and look at psoriasis: 1. Correctly recognize and frankly face. Psoriasis is a common skin disease, conservative estimates of China has nearly ten million patients. Among them, more than 90% are common type psoriasis, that is, the lesions mainly involve the skin, and generally have no great influence on the health of the body. 2, regular treatment, adhere to the treatment. Don’t blindly pursue cure, this is wrong and dangerous, many irregular institutions are using this point to cheat the majority of patients, profiteering, do not be in a hurry to seek medical advice, seek prescription, often encountered some patients so that not only shed money, but also lead to aggravation of the condition, health damage.

In addition, psoriasis, like hypertension, diabetes and other chronic diseases, requires long-term scientific and reasonable management in order to achieve the purpose of preventing and reducing recurrence. Is psoriasis related to season? Most psoriasis patients are heavy in winter and light in summer, and there are two reasons for this: one is ultraviolet light and the other is humidity. Ultraviolet light is therapeutic for psoriasis, in which narrow-wave ultraviolet light (NB-UVB) has been widely used in the treatment of psoriasis; compared with dry winter, relatively humid summer is more favorable for the repair of the skin barrier function, which is beneficial for the alleviation of psoriasis and the prevention of relapse. Is psoriasis related to diet, smoking and alcohol? Yes. Some studies have found that smoking and alcohol consumption are risk factors for psoriasis, so it is recommended that psoriasis patients need to quit smoking and alcohol. Diet, high-fat diet is also a risk factor for psoriasis, and psoriasis patients are often combined with hyperlipidemia, so they should reduce the intake of fats and oils, and for patients who are combined with obesity, appropriate exercise, low-calorie diet, weight reduction, is also beneficial to the control of psoriasis. In addition, in addition to the above factors, infection, trauma, surgery, psychological and mental stress often affect the occurrence of psoriasis. The recurrence of psoriasis is certainly annoying, and you need to correctly recognize and look at psoriasis and learn to accept it and manage it. Psoriasis needs scientific treatment, regular treatment and persistent treatment. I hope every psoriasis patient can control it well and establish a positive and optimistic attitude towards life instead of being beaten down by a small skin disease, and that there is still a brilliant sunny day behind the dark clouds.
