Allergic dermatitis hotel

Because the baby's digestive system is underdeveloped and the gastrointestinal function is fragile, it is easy to have abnormal reactions to certain foods, such as local rash, diarrhea, vomiting and other symptoms, and in severe cases, bloody stool, systemic rash and other symptoms. This is what people often say. Food allergy.

Any food can cause allergic reactions, but most babies' allergic reactions are usually caused by these six common foods: milk, eggs, peanuts (nuts), seafood, mangoes and pineapples. Allergic fruits and vegetables are less common and usually not too serious.

Milk is one of the most common allergic foods for babies. Generally, babies under one year old are most prone to milk allergy. According to statistics, 5% of babies are allergic to milk, and will gradually get better after 3 years old. Milk allergy is actually allergic to protein in milk, that is, the baby's immune system overreacts to milk protein.

Preventive measures: 1. For babies with a family history of allergies, we should insist on breastfeeding. 2, if the mother does not have breast milk for a few days after delivery, it is best to feed low-sensitivity milk powder according to the baby's actual situation, that is, moderately hydrolyzed whey protein formula. Milk protein is a heterogeneous protein for babies, and some components in milk protein, such as β-lactoglobulin, have strong allergenicity, which will lead to allergies in babies. Moderately hydrolyzed protein formula milk powder was treated by protease hydrolysis process, which changed milk protein macromolecules into smaller fragments, greatly reduced the allergic components of milk protein and reduced the allergenicity of improved milk protein. However, it should be noted that not all hydrolyzed protein formulas have the effect of preventing allergies, but have low allergenicity and potential preventive effects.

Eggs used to be very nutritious food, but when it comes to babies, it will become quite dangerous. Because many babies are allergic to eggs for the first time, and even life-threatening if they are serious. Egg allergy is an allergic reaction of the immune system, which is caused by the body producing antibodies to the eggs it eats. Sometimes, skin contact with eggs can also cause allergic reactions. Many people are allergic to eggs since childhood, but they usually disappear naturally after 5 years old. The immune system of allergic people regards protein contained in eggs as a dangerous substance and produces antibodies to resist it. It fights invaders by releasing immunoglobulin e. These antibodies will in turn release chemicals such as histamine to fight back. The problem is that the release of these chemicals will adversely affect the respiratory system, gastrointestinal system and cardiovascular system. All the symptoms of egg allergy will be obvious on the skin.

Preventive measures: 1. To confirm whether you are allergic to eggs, you must go through a detailed medical history, diet diary and a series of strict examinations by doctors (including avoiding suspicious food, skin prick test, serum specific IgE test, etc.). If the diagnosis is confirmed, the best way is to strictly avoid eating eggs and foods containing egg ingredients. Specific measures are as follows:

Peanut is an important food allergen, which can cause extremely rare severe allergies. Symptoms of peanut allergy include hypotension, swelling of face and throat, asthma, dyspnea and anaphylactic shock.

Precautionary measures: Because peanuts and other nuts come from different families of plants, the baby is very sensitive to peanuts, but he can also eat walnuts, walnuts and other nuts often, but be careful, because peanuts may appear in many unexpected foods, such as peanuts, which are often crushed and placed in foods such as candy. Peanut butter is sometimes used as an "adhesive" to preserve food, which is used in restaurants and hotels. Therefore, when buying food, you must read the precautions carefully to ensure that peanuts are not added. Allergy caused by nuts such as walnuts, cashews, Brazil nuts, almonds and hazelnuts can be as serious as peanut allergy, which should be paid attention to.

Animal foods such as fish, shrimp, crab and shellfish from the sea contain a lot of protein, which is rich in nutrition, but seafood is not easy to preserve and is prone to spoilage. Under normal circumstances, the human body can decompose histamine in fresh seafood, but histamine will proliferate rapidly after seafood spoilage. These stale seafood will absorb too much histamine if eaten by the baby, and it will easily cause allergies before it can be decomposed.

Precautionary measures: it is recommended that mothers should not give their babies high-risk allergic seafood such as shrimps and crabs too early. It is best to add it gradually after 1.5 years old. The principle is to add a small amount of items, and then increase the weight or add categories after confirming that the baby is not allergic.

Mango contains a lot of substances that irritate baby's skin, such as fruit acid, amino acid and protein. Immature mango also contains aldehyde acid, which will stimulate the skin mucosa and cause allergies. In addition, people who are allergic to mango are mostly allergic, and their immunity is generally low. For example, some babies are prone to allergic dermatitis after eating mangoes, mainly because the way babies eat mangoes is to "wash their faces", and it is easy to get juice on their faces and drop it on their bodies. Coupled with the baby's thin skin and poor resistance, the probability of suffering from fruit rash is much higher than that of adults.

Note: When eating mango, it is best to cut the pulp into small pieces and send it directly to the mouth. Avoid direct contact of mango juice with facial skin and reduce the probability of allergy. After eating mango, let the baby drink water to rinse his mouth and wash his face to reduce juice residue.

Three ingredients in pineapple may cause baby allergies. Pineapple contains a variety of "biological glycosides", which are irritating to baby's skin and oral mucosa. So after eating untreated raw pineapple, your mouth will feel itchy. "5- hydroxytryptamine" in pineapple is a neurotransmitter containing ammonia, which has a strong effect on vasoconstriction and smooth muscle contraction, raising blood pressure, and the result is headache. Every100g of fruit juice contains 2.5mg-3.5mg. Pineapple contains "bromelain", which is a protein hydrolase. After extraction, it has a strong function of decomposing fibrin and blood clots, and is a medical drug. A small amount of bromelain in pineapple is decomposed and destroyed by gastric juice after being eaten in the stomach. However, a few people have allergic reactions to this enzyme, and most of them are "quick-acting" allergic reactions. Abdominal pain, nausea, vomiting, urticaria (commonly known as rash), headache, dizziness and other symptoms occurred about 15-60 minutes after eating. In severe cases, dyspnea and shock may occur.

Precautionary measures: it is not advisable to add pineapple to your baby too early. In the order of adding baby complementary food, it is best to put pineapple after other fruits. Apples, pears, bananas, avocados, strawberries and other fruits are relatively more friendly and can be added first.

Once the baby has allergies, it is necessary to take appropriate measures in time.

0 1 Avoid allergic food

Babies have allergic reactions, some of which are caused by heredity. Most children will get older, and food allergies will disappear, and some will continue to affect adults. The easiest and best way to find allergic food after allergy is to avoid it. Immediately stop eating allergic foods and related foods containing allergic food formulas. However, children with mild allergies should be reassessed regularly to see if they need to avoid these foods.

Symptomatic treatment

After the specialist confirms the baby's food allergy, he will treat it according to the severity of the baby's symptoms and the degree of physical damage.

03 food substitution

If you are allergic to milk, you should continue breastfeeding, or change to deeply hydrolyzed protein formula or amino acid formula according to the situation; It is not recommended to use formula milk powder such as soy protein or goat milk, because 30% ~ 40% may be cross-allergic. Tips: Parents can't judge whether the baby is allergic according to the allergen test results, and then strictly fast food for the baby, which will affect the baby's growth and development. The negative or positive results of general allergen testing are for reference only and need to be decided by experts' comprehensive judgment.

In fact, many babies may encounter "food allergy", the little monster of the magic man. However, if the mother can aim at allergens and master the scientific method of arranging diet, the baby who is allergic to food can still grow up very well.
