Allergic babies have low immune function, many parents have a headache, how to improve the baby’s resistance, I personally provide the following recommendations: First, parents establish the right concept, to correctly understand that there is no special medicine can immediately improve the baby’s resistance, no matter how much hype the name of the health products, are so. Second, do not abuse supplements, allergic babies have a weak spleen and stomach, and intolerance to high-protein foods, intake of too much high-protein foods such as fish, shrimp, meat, eggs and milk, can only increase the burden on the body, reduce immune function, and increase the chances of allergies. Thirdly, we should pay attention to “natural food, balanced diet and regular eating”, the daily diet should be mainly starchy food and vegetables, while avoiding processed food, and we should pay attention to controlling the amount of food, avoiding overfeeding and not force-feeding. Drink more plain water as appropriate. Fourth, the author repeatedly communicate with parents and friends in the clinic, moderate common cold caused by moderate fever on the body’s immune function has an irreplaceable role of drugs, therefore, when the baby cold fever, do not rush to reduce the fever, not to mention the abuse of antibiotics and hormones in order to simply reduce the fever, there are a hundred harm but no benefit. Fifth, avoid adding too many clothes, too much clothing, baby is easy to “fire”, reduce resistance. Sixth, do not blindly apply antibiotics and hormonal drugs, some antibiotics such as azithromycin have anti-allergic effects, allergic cough application can reduce cough symptoms due to its anti-allergic effect, but its side effect is to cause immune dysfunction; and hormonal drugs (oral and nebulized inhalation) are the fastest effective drugs for the treatment of allergic diseases, but they directly inhibit the body’s immune function and aggravate immune dysfunction. Therefore, unless there is clear evidence of infection or wheezing is evident, the application of simple allergic coughing will not pay off in the long run and must be chosen carefully. Seventh, according to the child’s constitution to enhance the immune function through Chinese medicine, we should pay attention to the choice of experienced professional physicians, rather than hearsay, sickness and disorderly treatment.
