What kind of skin disease is psoriasis? Psoriasis, also commonly known as psoriasis, is a common chronic inflammatory skin disease characterized by papules, erythematous plaques or patches of varying sizes covered with silvery-white scales and clearly defined borders, most often on the scalp, extensor surfaces of the extremities and the back, and most have varying degrees of itching. It tends to recur or worsen in winter and spring, while remitting in summer and autumn. In addition to the common psoriasis, there are three special types of psoriasis: pustular, erythrodermic and arthritic. Although psoriasis is not life-threatening, it has a direct impact on physical health and mental and physical well-being Why do you get psoriasis? The causes of psoriasis are complex and the etiology is not yet clear. Recent studies have concluded that the occurrence of psoriasis is related to genetics, infection, metabolic disorders, immune dysfunction, endocrine disorders and psycho-neurological factors. Can psoriasis be cured? It should be said that after regular treatment, psoriasis can be controlled, relieved or even clinically cured. However, to date, no hospital or doctor at home or abroad is sure to be able to cure psoriasis at this level. Some of the small advertisements in newspapers, magazines or the internet that claim to be able to cure psoriasis are not enough to be trusted. Can psoriasis be transmitted to other people? Scientific research has not so far cultured infectious bacteria, fungi or other factors in the skin lesions of psoriasis. So far there is no evidence-based medical evidence that psoriasis is contagious. Therefore, psoriasis is not an infectious disease and the disease itself is not contagious. People with psoriasis can live and work like normal people, and enjoy the right and freedom to enjoy life. Will psoriasis be inherited to the next generation? Research shows that there is a correlation between psoriasis and genetic factors. Some studies show that if one parent has psoriasis, the probability of inheritance is about 14%; if both parents have psoriasis, the probability of inheritance is about 41%. However, heredity is not a decisive factor in the occurrence of psoriasis, and the onset of psoriasis is often more common when triggered by environmental, mental and infectious factors. Even familial psoriasis does not occur in everyone, and more psoriasis patients have no history of psoriasis in their fathers or grandfathers. Why does psoriasis tend to recur after a cold? Some patients with punctate psoriasis, arthritic and erythrodermic psoriasis often have symptoms such as upper respiratory tract infection or tonsillitis, and in these patients the application of antibacterial drugs such as penicillin can often achieve better results. This shows that local foci of infection are an important cause of psoriasis, which is generally considered to be the result of a metamorphic reaction to bacterial toxins. Therefore, strengthening exercise, improving the immunity of the body, avoiding wind and cold, and being cautious about living have certain significance in preventing relapse. Will a good or bad mood directly affect psoriasis condition? Psoriasis is a physical and mental disease, that is to say, psychological factors play an important role in the occurrence and development of psoriasis. Anxious emotions and mental tension can trigger and aggravate psoriasis. Therefore, this disease needs not only drug treatment, but also psychological health care and overcoming anxiety. It is especially important for psoriasis patients to understand the disease correctly, to achieve a stable state of mind, and to maintain a good state of mind and psychological quality for psoriasis patients. What aspects of the diet of psoriasis patients should be noted? Generally speaking, psoriasis patients should avoid eating spicy and warm products such as shrimp, crab and seafood, mutton, chili pepper, tobacco and alcohol in their diet, while chicken, duck, pork, eggs, river fish, milk, vegetables and fruits should be consumed sufficiently to ensure nutrition. Although the diet should be contraindicated, it is not a generalization, and should vary from person to person. If the skin lesion worsens after the intake of certain foods, it should be controlled, or consult a doctor at the hospital.
