Baby allergy generally refers to children’s skin allergy
Common skin allergies in children include contact allergic dermatitis and photosensitive dermatitis. Contact allergic dermatitis is an acute or chronic dermatitis at the contact site due to skin or mucosal contact with sensitizing substances. Photosensitive dermatitis is characterized by contact with photosensitive substances or substances, and then exposed to ultraviolet radiation, erythema, swelling and blisters may appear within 12 hours. Children’s skin allergy is more common than adults, because the baby’s skin is more delicate than adults, so it is more prone to skin allergy, dry skin and other conditions.

Many common allergens of children’s skin allergy are children’s favorite food, habitual drinks, favorite smell or places where they often play, so they are often ignored. Children often show skin allergy, physical discomfort and behavior problems soon after exposure to allergens.
Common sensitizing foods include: milk and dairy products, flour, corn, eggs, sugar, tomatoes, potatoes, chocolate, yeast, edible pigments, fruits, beef, pork, etc.
The common allergenic environmental factors are pollen, mold, dust, trees, tobacco, smoke, perfume, gasoline, paint, insecticide, cleanser, medicine, pets, carpets and so on.
Cause of disease
Children’s skin allergy is an inflammatory skin disease characterized by redness, swelling and itching. After the allergy, the baby will scratch and cry repeatedly. In serious cases, it will also cause loss of appetite and affect the mental state. Allergies can be inherited. If parents are allergic to pollen, pets or certain foods, children are also 50% likely to suffer from allergies. If both parents have allergies, the child’s risk of allergies will reach 75%, as will skin allergies. Children’s skin allergy is more common than adults, because the baby’s skin is more delicate than adults, so it is more prone to skin allergy, dry skin and other conditions.
When the baby has skin allergy and a red and itchy rash, it may be easy to think about whether the baby’s daily use of toiletries has caused skin allergy. In fact, the rash of skin allergy may be caused by a variety of reasons. Don’t simply think that it’s OK to stop or replace skin care products, but ignore the real “culprit” of baby’s skin allergy. Babies with inherited allergic constitution are more likely to have allergic reactions, and skin rash is a typical symptom of children’s skin allergy. Pay attention to observation in daily life and prevent it early. Breastfeeding can prevent baby’s skin allergy to a certain extent. You can consider breastfeeding your baby for as long as possible, especially when there is a family history of allergy.
Symptom performance of Children’s Skin Allergy
Skin allergy symptoms usually take several forms. One is sensory symptoms, such as itching and tension; One is explicit symptoms, such as redness, scaling, redness and swelling. Of course, more serious is both symptoms. Children’s skin allergy symptoms include general symptoms and behavioral changes, which often occur half an hour to several hours after children’s exposure to allergens.
General symptoms
Children have flush cheeks, nose and earlobe, moist ear canal, earache, stuffy nose, sneezing, dark circles, eyelid swelling and drooping, headache, dry lips, dry skin or sweating, wrinkles in corners of eyes or palms, abdominal pain, diarrhea, abdominal distention, constipation, wet rash on arms, legs or joints, repeated infection, chronic cough, asthma, shallow and fast breathing or irregular, pulse disorder, Elevated blood pressure, tight joints, etc.
Behavior change
Children of different age groups behave differently.
0 ~ 1-year-old infant group: continuous crying or screaming, unable to eat or need to eat continuously, irritable or extremely depressed, difficult to fall asleep or sleepy, unwilling to be held, shaking his head, etc.
Children aged 1 ~ 3 years old: inexplicably lose their temper, become overly active, jump around, hit the bed, get tired, curl up under tables and chairs, under the bed or in the furniture and other dark corners, refuse to be contacted, and are unwilling to dress or strip, etc. Children aged 3 ~ 6 years old: sudden changes in mood and behavior, hyperactivity, unable to sit quietly, eat, listen to stories or watch TV programs, irritability, fatigue, disobedience, depression, aggressive behavior, shaking legs, sleepiness or nightmares, unable to write or draw on a horizontal line, or the larger the words are written and tilt upward (excited type), or the smaller the words are written and fall downward (depressed type), Intermittent speech difficulties, bed wetting after the age of 5, etc.
Allergy prevention in children
“Allergic children” can be prevented. When the child is not born, or even when a new life has not been formed, there are many factors affecting whether the child will become an “allergic child”.
Therefore, the prevention of “allergic children” should start with premarital counseling. Genetic studies have proved that one of the parents has allergic diseases, and the possibility of their children becoming “allergic children” is 60%; Both parents were patients with allergic diseases, and the possibility of producing “allergic children” increased to 80%; In contrast, only 19% of the children whose parents have no allergic diseases may become “allergic children”.
Therefore, experts suggest that intermarriage should be avoided between men and women with allergic constitution. In addition, according to foreign research reports, infants born in autumn are more likely to suffer from allergic diseases such as asthma than those born in other seasons, so autumn delivery should be avoided as far as possible.
Infants with a history of allergic diseases are easy to become “allergic children” in the future. For these high-risk infants, exclusive breastfeeding shall be guaranteed for 6 months after birth, and the breastfeeding time shall be delayed to 9 months after birth. No supplementary food shall be added within 4 months after birth, especially milk, eggs and other foods rich in heterosexual protein. Fish, shrimp, crab and shell foods are highly sensitized substances and shall not be eaten before the child is 4 years old. If breast-feeding women ingest foods containing high allergens, these food components can be detected in breast milk after 2-6 hours, and can last for 1-4 days. Therefore, mothers of high-risk infants should not eat milk, eggs, seafood, nuts (such as peanut) and other foods during breast-feeding. In the past, it was thought that if pregnant mothers avoid eating the above foods, they can reduce the chances of allergic diseases in the future, but recent studies have denied this view. Therefore, pregnant expectant mothers do not need to restrict any food.
In short, even if children have allergic constitution caused by heredity, as long as effective intervention measures are taken as soon as possible, they can still avoid allergic diseases and become healthy children.
Therapeutic method for Children’s Skin Allergy
In the process of children’s skin allergy, allergic mediators play a direct role. Allergens are the necessary conditions for the occurrence of allergic diseases, and the existence of a large number of free radicals is the root of children’s skin allergy. Free radical oxidation destroys the cell membrane of mast cells and basophils, makes them damaged and denatured, and the immune ability of the body is low, which creates conditions for the occurrence of antigen and antibody allergic immune reactions, leading to cell rupture and the release of allergic mediators, resulting in allergic diseases. Most antiallergic drugs compete with allergic mediators for nasal mucosa, skin blood vessels and bronchial smooth muscle cells, so that allergic mediators can not work. Once the drug is over, allergy will still relapse. Moreover, many drugs will also make users drowsy. Although some aerosol hormone drugs take effect quickly, they have greater symptoms and side effects when they relapse. The root of allergy is the patient’s allergic constitution. To treat skin allergy, we must start with improving the allergic constitution.
Control environment
The simplest way for infant skin allergy is to avoid contact with allergens and stay away from allergens, so that the patient’s allergic constitution will not contact allergens, which will not stimulate the body to make a strong response to allergic substances and induce allergy.
Improve allergic constitution
(1) People with allergic constitution have more immunoglobulin IgE (antibody mediating allergic reaction) than normal people. Once patients encounter allergens, the body will respond. It is the reaction between immunoglobulin and allergen substances, which leads to mast cells releasing histamine to the corresponding tissues, thus causing allergy.
(2) There is a certain proportion of adult human helper T cell 1 and helper T cell 2, which play a role in regulating the balance of human immune system in human circulatory system. (3) There are many digestive enzymes in the gastrointestinal tract of normal people, which are protein foods entering the gastrointestinal tract for complete digestion and absorption.
(4) Allergic constitution can be inherited. Strengthening the immune system and improving the above symptoms is to improve allergic experience and eliminate allergy.
Children with skin allergy should pay attention that children are in the prime time of production and development, and their bodies are immature in all aspects. Therefore, in the treatment of children’s skin diseases, we should pay attention not to use some hormones and anti blocking amines, which will have adverse effects on children’s bodies. 
For example, the current infants use milk powder containing hormones, resulting in poor physical development of infants, Some even use too much hormone, and the child stops growing. Children’s mothers can use some physical methods: for example, they can change their children’s clothes frequently, wash more sheets, etc.
Preventive measure for Children’s Skin Allergy
Dietary health care
To eliminate the baby’s skin allergy, it is best to feed breast milk, which can greatly reduce the generation of allergy. Breastfeeding is best maintained for up to six months. Generally, the baby can add supplementary food at about four months, and the baby’s skin allergy can only be added after six months. If the intestinal absorption is still unstable at the age of six months and it is easy to vomit, the time of adding supplementary food should be prolonged. In addition, the diet of infants and young children should be light, and the seasonings and pigments should be reduced as much as possible.
Reduce dust in the bedroom
To eliminate the baby’s skin allergy, reduce the dust in the bedroom, keep the indoor environment clean, wipe it with wet cloth frequently, and change and wash children’s sheets, quilt covers, pillowcases and other articles frequently. To avoid the occurrence of children’s skin allergy.
Partially hydrolyzed protein milk powder to prevent milk powder allergy
Partially hydrolyzed formula milk powder, such as Abbott Pro care, can be used to prevent milk powder allergy because of its low sensitization. Compared with ordinary formula milk powder, it is not easy to cause milk powder allergy.
Control the humidity of the environment
Bacteria are easy to breed in humid environment, and it is appropriate to have an environmental humidity of 50%.
Dr. Bo He (My TCM consultant) How is child allergic constitution treated, Ma Baohai, deputy chief physician, child health department, Weifang maternal and child health care hospital
Allergy is a very common problem. We always have several allergic experiences from birth to growth. Allergy is a complex disease with a variety of reasons, including food, drugs, environment, gas and so on. However, there is also a group of people with natural allergic constitution. If it is allergic constitution, you must pay special attention at ordinary times, otherwise measles, dermatitis and asthma will occur repeatedly. So, how to treat children’s allergic constitution?
1、 Treatment of allergic constitution in children
If the child is found to be allergic, go to the hospital to check the allergen as soon as possible to see what his sensitizing substance is, and avoid contact with allergens during allergy. Secondly, in the later stage, you can slowly contact the sensitizing source in a step-by-step way to desensitize. If there is no way to desensitize, try not to contact sensitizing substances.
2、 Precautions for allergic constitution of children
1. Enhance physique
For those people with repeated allergies, most of the reason is their low immunity and unable to resist the invasion of the virus. Therefore, we must do more physical exercise at ordinary times. We can take time to exercise at least 3-4 days a week. When exercising, you should choose appropriate exercise methods to avoid excessive exercise. Suitable sports for children include rope skipping, running, yoga, swimming, etc. the specific choice may need to be judged by children.
2. Supplement high nutritional food
If it is allergic constitution, you must pay attention to eating more nutritious things, such as eggs, ribs, mutton, bean products, etc. eating more of these foods can supplement your own resistance. Secondly, eat more fresh fruits and vegetables, which are rich in vitamins and dietary fiber, which helps to improve your physique.
3. Avoid fatigue
If a child has an allergic constitution, be sure not to let the child be too tired. As soon as the child is tired, his resistance decreases, his own immunity can’t keep up, and then he begins to get sick. Therefore, we should pay more attention to children’s rest at ordinary times. If it is difficult to study, we should pay too much attention to it. We should have a rest every day when it is time to avoid staying up late repeatedly because of learning.
