Pruritus troubles many people
According to a reporter's survey, more than seven adults have had unexplained skin itch in their lives, of which 90% of the elderly have skin itch; six adults said that 'if the itch is not severe, they will not go to the tube', three adults will 'find a way to stop the itch by themselves' (such as using drugs), and only one adult will find out the reason after' skin itch '; The skin problems of young white-collar workers are obviously on the rise because of their living habits and working pressure; children can't express them correctly because most of them can't find the reasons after itching.
According to a survey of the World Health Organization, less than 10% of yellow people have healthy skin, more than 20% of them are sick, and 70% of them are sub healthy. Pruritus is the first feeling described by 80% of dermatosis patients when they state their own feelings. 'after all, a small number of people come to the hospital to seek help from doctors. Many people choose to endure it or not take itching seriously at all. 'said Yang Shuxia.
Glenn Middleton giesler, Professor of Neuroscience at the University of Minnesota, said: 'after decades of research on "itch", we found that there are at least 50 reasons for people to feel itch. The main reasons can be summarized as follows'.
Simple skin problems. 'there are two ways to feel itchy because of skin problems. 'said Glenn Middleton giesler. One is that there is no primary skin damage, mostly due to the lack of water in the skin. Like now in the dry winter, many people will feel the skin dry itching, peeling. Another is the skin itself on the 'disease', dermatitis, eczema, psoriasis and other skin diseases are mostly accompanied by pruritus.
The skin of middle-aged and old people degenerated. The skin of the middle-aged and old people becomes dry because of atrophy and thinning of skin, decrease of water content, decrease of secretion of sebaceous glands and sweat glands, and loss of lubrication and protection. In the cold season, the dry climate makes the skin rough, even the epidermis falls off, making the nerve endings in the skin more easily stimulated and itchy. The reason is that the old people are itchy.
Allergy. Professor Liu Guanghui, chief physician of the allergy Department of Wuhan Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of science and technology, said: 'clinically, one third of the patients in the allergy department have itchy skin. They are allergic to food, pollen, dust mite and other chemicals, which may cause allergy and itch the skin. This kind of itch will improve after stopping contact with allergens.
gynecological inflammation. If women find pruritus in vulva, they should check for trichomonad, Candida albicans infection and other gynecological inflammation. According to the survey, 73% of women will feel local skin itching during menstruation, which may be related to poor quality of sanitary napkins or too tight clothing.
Emotional tension. Depression, tension, irritability and other bad emotions may cause local or systemic skin itching. B vitamin deficiency also causes skin itching.
Hepatobiliary diseases. Hu liming, deputy chief physician of gastroenterology department of Oriental Hospital Affiliated to Beijing University of traditional Chinese medicine, said: 'many systemic diseases can also cause skin itching. Some studies have shown that about 40% - 60% of patients with hepatobiliary diseases will have skin itching when the liver is uncomfortable, liver function is abnormal and jaundice occurs.
diabetes. The incidence of skin pruritus in diabetic patients is as high as 15% - 35%. About 10% of early patients will have systemic or local skin pruritus, which is stubborn, and the symptoms of vulva or anus are the most serious.
Abnormal thyroid function. Whether it is hyperthyroidism or hypothyroidism, skin itching may occur, but the itching caused by hyperthyroidism develops slowly and the skin is dry, which will be aggravated in winter.
Malignant tumor. Some tumors occur with skin itching, such as lymphatic system, stomach, intestine, liver, ovary and prostate cancer. This kind of itch caused by tumor is mostly stubborn. If your body has itch for a long time without cause, you need to pay attention to it.
Professor Liu Guanghui said that the first thing to do is to identify whether it is allergic phenomenon caused by contact with some allergens. Secondly, we should go to the dermatology department to eliminate the problem of skin itself and see if the skin itself is' sick '. Finally, if pruritus occurs due to other diseases, it should be treated in time.
