Nine factors inducing psoriasis recurrence 1, mental and nervous factors Skin is a very emotional organ, which is one of the important expression organs of internal psychological activities of human body. Long-term clinical observation has found that the occurrence and development of psoriasis are closely related to the patient’s personality, emotion, tension, worry, anxiety and other mental psychological factors. Psychological factors are important factors in the occurrence, aggravation and recurrence of psoriasis. Psychological factors mainly include (1) bad emotions, such as tension, anxiety, panic, anger, depression, worry, grief, etc.; (2) stressful life events, such as family disputes, death of loved ones, change of job, exams, etc.; (3) excessive fatigue, sleep disorders and so on. 2.Physical factors Cold temperature is unfavorable to psoriasis. Most of the psoriasis patients have their condition relieved in summer, but their condition is easy to recur and aggravate in fall, winter and spring, which may be related to the cold and dry outside temperature and the shortened sunshine time in winter. Darkness and dampness can aggravate the condition. Scholars at home and abroad generally believe that dampness can induce or aggravate psoriasis. 3.Lifestyle (1) Smoking is a risk factor for psoriasis (2) Excessive alcohol consumption can easily trigger psoriasis (3) Lack of physical exercise can aggravate psoriasis (4) Staying up too late can lead to recurrence. 4.Dietary Factors (1) Try to eat as little as possible of the meals that may trigger or aggravate psoriasis. Such as seafood; a variety of “red meat”; animal fat; a variety of spices, certain vegetables: coriander, parsnips, peppers, garlic shoots and so on, it is best to eat less. (2) Diets that are favorable to the alleviation of the disease. Such as fresh fruits: apples, bananas, oranges, etc., which can be eaten frequently; vegetables: loofah, asparagus, celery, etc.; coarse grains: corn, brown rice, oats, etc.; a variety of soybean products: such as bean curd, soymilk, etc. 5, trauma Trauma mainly refers to skin injuries, physical trauma and mosquito bites, etc., which is a common triggering cause of psoriasis. 6.Infection factors Infection factors are one of the risk factors for triggering and aggravating, including infections of bacteria, germs and fungi. Although infection can induce and aggravate psoriasis, infection does not directly lead to psoriasis lesions, that is to say, psoriasis lesions are not caused by microbial infections, and psoriasis is not an infectious disease. 7, drug factors Some drugs are also one of the triggering factors of psoriasis, and it is common to see psoriasis patients taking drugs for a long time due to the combination of other diseases, which triggers psoriasis or makes the condition prolonged and intractable. 8, allergic factors In the clinic, it is found that a considerable part of psoriasis patients are allergic, and may suffer from urticaria, eczema, dermatitis and other allergic skin diseases at the same time. 9, endocrine metabolic factors (1) sex hormones, domestic and foreign epidemiological surveys on the prevalence of psoriasis show that: the age of onset and peak of female is earlier than that of males, and it is presumed to be related to the fact that the sexual maturity of females is earlier than that of males. (2) Glucose metabolism, many scholars at home and abroad have found that psoriasis patients have strong insulin resistance, and some studies have shown that the value of PASI score of psoriasis patients is positively correlated with the level of insulin resistance factor in serum. (3) Obesity, exercise, improve dietary habits, etc. to reduce weight, may be more effective in alleviating the condition of obese patients. Facing the recurrence of psoriasis is a principle: slow treatment of slow disease Previously, we have analyzed a variety of factors that induce the recurrence of psoriasis, but no matter what factors cause the recurrence of psoriasis, the patient must realize that psoriasis is a chronic skin disease, “slow treatment of slow disease” is the face of its scientific attitude. “Slow treatment” can be understood from two aspects: 1, to be slow, that is, adjusting the mentality, not anxious and not impatient. For psoriasis and other chronic skin diseases, no matter what treatment is used, patients can not hope to see a complete cure, or a clinic can be once and for all. Clinically used drug therapy and ultraviolet light therapy, in a more ideal state also need about two months to achieve good therapeutic effect, for the more serious or known to be more prone to recurrence of the patient, the course of treatment may be longer; relapse, often need to use a similar course of treatment. Patients have a “slow” psychological preparation, but easy to calm the mind, optimistic response, which is the most favorable prerequisite for any therapeutic approach. 2, to cure, that is, believe in science, adhere to the treatment. Although the results can not be immediate, but if in each method has not yet seen the effect of the time to give up or another method, the treatment is sure to fail. In short: persistence is victory. Of course, patients can not adhere to the treatment in addition to the eagerness to achieve the psychological, but also because of the actual difficulties faced by the patients, such as long-term treatment repeated running more tired, busy work and study can not find time for regular treatment. In terms of medication, after hospitalization and discharge from the hospital, some medications are still needed to maintain the treatment. In terms of ultraviolet light therapy, for some patients with milder conditions, shorter duration of illness or fewer affected areas, the frequency of going to the hospital for light treatment can be gradually reduced, and small light therapy equipment can also be used at home for self-treatment under the guidance of a doctor. The advantages of self-medication and self-medication at home are flexible and free time, free from traveling, comfortable treatment environment, easy to protect the privacy of patients, patients with less financial burden, etc. Therefore, it is easier for patients to adhere to the treatment and achieve good results, but also conducive to the maintenance and consolidation of therapeutic effects; in the event of a relapse of the disease, the patient can also be used in the same way to control the disease as soon as possible. Of course, for patients with more serious conditions or generalized disease, it is still recommended to go to the hospital to receive standardized treatment.
