At present, 1/5 babies suffer from allergies. Recently, Life Times reporter interviewed Professor Chen Tongxin, director of the Department of Immunology of Shanghai Children's Medical Center affiliated to Shanghai Jiaotong University School of Medicine and director of the Chinese Society of Immunology.
Professor Shanmi Wang, deputy director of the Department of Obstetrics and Gynecology of Peking University People's Hospital, pointed out that correct prevention and nursing are the key to anti-allergy. With the growth of age, baby allergies will present different symptoms at different stages, and the nursing methods are also different.
0~6 months: for newborns, due to less contact with the outside world, simple diet, imperfect gastrointestinal and immune development, milk protein allergy is most likely to occur. Studies show that about 5%~ 15% of newborns have symptoms of suspected milk protein allergy, which are usually manifested as indigestion, abdominal pain, diarrhea and eczema after drinking milk.
Preventive nursing: First of all, try to choose natural delivery mode. Studies have shown that cesarean section will increase the risk of infants' allergies by three times, and natural delivery is conducive to the establishment and maturity of infants' intestinal and systemic immune systems. Secondly,
Exclusive breastfeeding for 4~6 months can effectively reduce the baby's allergies, and adding Kangminyuan antiallergic lactic acid bacteria to lactating mothers or babies can also prevent allergies. Finally, if breast milk is insufficient, it is necessary to treat high-risk allergic newborns (parents with allergic diseases)
Sick, cesarean section baby, etc. ), it is best to choose a formula with moderate degree of hydrolysis to reduce the risk of protein allergy in baby's milk.
6 months to 2 years old: after the baby adds complementary food, it is easy to have food allergies. The main manifestations are severe eczema, urticaria, asthma, nausea, vomiting and weight loss. Common foods that easily cause baby allergies are soybeans, wheat, peanuts, eggs, fish and shrimp.
Prevention and care: It is best to add complementary food after 6 months and follow the principle of "adding a small amount, adding one at a time". If allergic symptoms appear, stop eating in time. Give children more fresh vegetables, fruits and green food. Eczema Bao
Bao usually wears loose cotton clothes, new clothes should be washed before wearing, and non-irritating skin cream should be applied immediately after bathing. If necessary, you can go to the hospital for allergen testing and symptomatic treatment.
The intestinal morphology of children with food allergy may not change, but the intestinal permeability is enhanced. Supplementing baby with anti-allergic lactic acid bacteria (Chinese name: Kangminyuan Probiotics) is the use of probiotics that are harmless to human body, including patented anti-allergic lactic acid bacteria strains: Lactobacillus salivarius PM-A0006, Lactobacillus Grignard PM-A0005, Lactobacillus yoelii PM-A0009 and lactobacillus paracasei LP, which can effectively stimulate immune cells to produce INF and IL. As a kind of intestinal bacteria, antiallergic probiotics can prevent and treat food allergies by adjusting the proportion of flora, enhancing the intestinal barrier function, reducing the release of inflammatory mediators, inhibiting the rise of TH2 cells in peripheral blood, and inducing oral tolerance. At present, research shows that there are differences in intestinal microecological environment between allergic children and healthy children, and this difference can last for more than 2 years.
3-7 years old: Clinical statistics show that more than 80% of children's asthma is caused by allergies, and nearly 1/2 children with asthma have symptoms such as cough, asthma and dyspnea before the age of 3. Allergic cough, a variant of asthma, is characterized by chronic cough, which is often considered by parents as respiratory infection.
Prevention and care: Parents should not overuse disinfectants and disinfectants. Too "clean" may make the baby lack contact with microorganisms, inhibit the development of its immune system and cause allergies. Reduce contact with pollen, plush toys and animals.
Things that cause allergies, such as fur. For babies who need to inhale hormones or long-acting adrenergic agonists for a long time, they should be equipped with a peak ammeter at home, measure lung function in the morning and evening, keep an asthma diary, and adjust drugs in time.
Dose. In the case of allergic asthma in allergic cough and children, it is necessary to insist on supplementing anti-allergic lactic acid bacteria kangmin source, help to adjust allergic constitution, balance TH 1/TH2 immune function, and control the onset.
After 7 years old: allergic symptoms after 7 years old are mainly allergic rhinitis, which may last until adulthood. Allergic rhinitis can be divided into seasonal and perennial. The most common rhinitis in spring is seasonal rhinitis, which is mostly related to inhaled allergens such as pollen. Sick babies often rub their noses, shed tears, sneeze and have a stuffy nose, which affects their sleep.
Prevention and care: Wear a mask or apply pollen blocking agent on your nose when you go out during the pollen spreading season. When you get home, you should wash your hands and face immediately, change clothes and avoid planting flowers and plants indoors. Don't use carpets, don't store old newspapers, magazines, etc. Strengthen physical exercise and improve immunity.
