Atopic dermatitis many parents have misconceptions about avoiding the mouth, blindly avoiding the mouth leads to delayed growth and development of the child, as well as avoiding the mouth after the child’s immune system can not be established in time, more baby skin lesions and itching aggravated, leading to a vicious circle. 1, breast milk allergy problem. First of all, breast milk is the best source for babies, one is the best nutrition with; second, there are many antibodies in breast milk, which can enhance the baby’s resistance; third, the source of breast milk is economic, easy to feed, the temperature is not high or low; fourth, breastfeeding can increase the parent-child relationship and so on. If the mother eats something such as crab one day and the baby’s skin lesion worsens, a comprehensive analysis is needed. If after a period of time, the next time you eat that kind of food, the skin lesions do not change much, it has nothing to do with this kind of food (theoretically the 2nd allergy is more serious than the last), if it is still aggravated, it is definitely an allergy and the mother needs to avoid eating it. 2. The problem of breast milk substitutes. If the amount of breast milk is not enough and formula is needed, what should we do if the baby is small (under 6 months), specific allergens cannot be detected, and the baby has no system that has not been established? The best way is to test food stimulation, first eat with ordinary milk powder for a period of time (more than half a month), if there is not much change from the previous lesions, it may not be related to milk powder allergy, and not every baby is allergic to milk powder. If the allergy is repeatedly aggravated, the baby must be allergic to regular milk powder. It is recommended to take amino acids under 6 months and deeply hydrolyzed milk powder over half a year old. If the baby is more than half a year old, it is best to test for specific allergens. If the baby is allergic to milk, he can only eat deeply hydrolyzed milk powder. 3. On the issue of allergen testing. The clear international recommendation for atopic dermatitis is atopic allergen testing (lab test IgE), not the so-called food intolerance (lab test IgG), not to mention the so-called bioresonance, pointing the finger. Specific allergen testing explains that a certain test value can only represent 95% of people and cannot include 100% of the problems. It should be noted that a positive most people are allergic to eating that food and a negative means that they are not allergic to eating that food. However, there are exceptions, you may have a very low test (negative) and also have an allergy. A very high test value (positive) and no allergy. This means that the baby’s test value is not in the normal range of normal human testing. Secondly, the specific allergen test checks for type I allergic reactions, while eczema is a type IV allergic reaction (patch test) and atopic dermatitis is a mixture of type I and type IV. The best way to determine if it is a food allergy is the food provocation test, which is the same as in real life situations (except for high sensitivity, which can cause acute shock). Specific allergen test negative, you are still worried, you can start a kind of small dose, gradually and gradually dose, more than 10-15 times in a row, no aggravation, indicating that certainly not allergic, can be safe to eat. If 1 time aggravated, it may be related to it, next time if also aggravated, definitely allergic, if this time is no reaction, that does not allergic. Specific allergen test positive, there are skin lesions may not be able to try, can only be no skin lesions, but also want to eat, can only try from a very small very small dose, very careful to try, increase the dose can not be too fast, the same method as before, if allergic to be determined not to eat, if more than 20 times, are not allergic, should not be a big problem. In addition, if in life, eat a certain food, each time aggravated or skin lesions, also indicates that is allergic, need to avoid the mouth. 4, atopic dermatitis will be better after the taboo misconception. If it is a food allergy, the skin lesions will be 40% better after avoiding the mouth, it will not be avoiding the mouth, atopic dermatitis is no more. If you have a food allergy, you will not be allergic for a short period of time, at least 3-5 years (your immune system will recover, and you may not be allergic). Do not try it again and again in a short period of time, this will only stimulate the allergic reaction to aggravate and affect the health of the baby.
