Affected by various internal and external factors, the incidence of children's allergies has increased significantly. In addition to common symptoms such as sneezing, runny nose, rash and diarrhea, cough is also a typical manifestation of allergies. Compared with the cough caused by respiratory infection, allergic cough has a typical performance of "three coughs a day", that is, coughing for a while before going to bed, waking up at night and getting up in the morning. Cough at night seriously affects children's sleep, and if it is not treated in time, it will even hinder children's normal growth and development.
Because of the great difference between different children, it is often difficult for parents without medical expertise to tell whether cough is caused by respiratory infection or allergy. If you give your child drugs without a clear diagnosis (even over-the-counter drugs that can be bought directly in pharmacies), sometimes it can have a certain effect, but it is easy to cause other negative effects. A professional pediatrician should make a scientific and comprehensive evaluation of children's cough symptoms. In this process, allergen detection and lung function detection are essential.
If it is confirmed that the child is allergic cough, you must take good care of it. These three ways of raising a baby are unacceptable:
1, allergic cough is a cold.
It is not feasible to treat children in allergic cough with compound cold medicine and antibiotics. Allergic cough is a polygenic autosomal dominant genetic disease, and its pathogenesis is based on atopy, that is, allergic children. It is found that Th2 is the main response to allergens in fetus and plays an important role in avoiding immune rejection between mother and baby. The type of immune response to allergens after birth determines whether allergic diseases occur: healthy children tolerate allergens to avoid Th2 reactions, while children who cause allergic symptoms such as allergic cough's disease, asthma, rhinitis, eczema, atopic dermatitis, urticaria, food allergy and drug allergy can be sensitized to allergens and induce an overactive Th2 reaction. Secondly, under the immune response dominated by Th2 immune response, such as contact with allergens, high levels of allergen antibody IgE are more likely to be produced in the body, which is the most important susceptible factor in allergic cough and the etiological source of repeated allergic cough. Some parents will say that children are never allergic when they are young, but they are easily diagnosed as allergic cough when they go to kindergarten. In fact, this Th2-based immune atopic constitution usually takes a period of sensitization to show up, so most cases in allergic cough appear gradually after birth 1 year-old or school-age children, and some even become ill in adulthood.
At present, the specific mechanisms of allergen tolerance in normal children and lack of tolerance in allergic cough children are not clear. Recent studies show that children's immune tolerance to allergens is mediated by the secretion of IL- 10 and IFN secretion to regulate T cells and induce Th 1 immune response. So as to enhance the immune defense function of children with allergic cough and improve their environmental adaptability. Xinmin Kang antiallergic probiotics are compound antiallergic probiotics composed of five patented antiallergic probiotics, among which Lactobacillus salivarius, Lactobacillus Grignard, Lactobacillus yoelii, Lactobacillus lactobacillus paracasei and Lactobacillus Roy all have significant antiallergic functions, among which Lactobacillus salivarius is the most researched strain, and Lactobacillus salivarius, Lactobacillus Grignard, Lactobacillus yoelii and lactobacillus paracasei form five compound antiallergic strains, which obviously reduce the individual differences of antiallergic functions, and have immunomodulatory antiallergic effects compared with a single antiallergic strain.
Diet is especially important for babies with allergic cough. Frozen and spicy food can irritate the throat and make the cough worse. It is not advisable to drink carbonated drinks to avoid inducing cough attacks. Sour food often accumulates phlegm, which makes it difficult to cough up, thus aggravating the condition and making cough difficult to recover; Do not eat peanuts, melon seeds, chocolate, etc. Compared with the above food, the food contains more oil, and it is easy to breed sputum after eating, which makes the cough worse; Less salt and less sugar. Eating too salty can easily induce cough or make it worse. When coughing, the diet should be light, and salty foods such as salted fish and bacon should not be eaten. As for sweets such as candy, eating more helps to clear away heat and phlegm, but also eat less; Don't eat or eat less fried food, and drink more water. When coughing, the gastrointestinal function is weak, and fried food will increase the burden on the gastrointestinal tract, help damp heat, breed sputum, and make cough difficult to heal.
3. Don't avoid allergens in time
Pay attention to stay away. If there are many allergens, you can go to the hospital for allergen screening.
These are some symptoms of allergic cough, prevention and treatment methods for everyone. Therefore, when children have this cough symptom, they should always drink water and let them have a light diet. If it is particularly serious, they can use inhaled corticosteroids for anti-inflammatory treatment.
