When Xiao Kai was 4 months old, his mother made a steamed egg for him to eat. Xiao Kai ate the whole portion with relish. Three hours later, a red rash appeared on his face, and his mother took him to the doctor immediately. The pediatrician diagnosed mild food allergy, and after taking antihistamine drugs, the allergic symptoms of skin rash subsided.
Hong Qianhui, a pediatrician at Taichung Hospital, pointed out that an abnormal immune response caused by food is a food allergy. A small amount of food allergy can cause symptoms, and severe anaphylactic shock can result.
The most common cause is IgE (immunoglobulin E), which occurs within a few hours of ingesting the allergen. Symptoms include prurigo, itchy nose, watery eyes, abdominal pain, vomiting, diarrhea, angioedema, Difficulty breathing, shock.
Food allergies that are not caused by IgE are less common. It takes several days to react. Allergic symptoms are suspected after eating food for a while. The symptoms are mainly abdominal pain, diarrhea, malabsorption, and pulmonary hemorrhage. .
. A 2015 LEAP study found that eating peanuts at 4 to 6 months of age was significantly less likely to develop allergies than those who started eating peanuts after 1 year of age.
Therefore. Both the BEAT and PETIT studies concluded that early egg delivery was recommended.
Hong Qianhui said that most food allergies will improve with age and will not recur, but if the symptoms are too severe, accompanied by other allergic diseases, and the detected allergy index is too high, there may be noLaw healed.
In terms of food types, about 45% of people with soy allergy are relieved at the age of 6, and about 50% of patients with wheat allergy are immune at the age of 7. However, peanuts are only 20-25% likely to be immune.
Hong Qianhui further explained that the baby's intestinal cell barrier is not complete, and allergens easily enter the bloodstream without digestion, causing allergic reactions. It is recommended that parents pay attention to the symptoms of the baby after ingesting food. If the baby eats a certain food and develops allergy symptoms, don't panic first, you can observe the severity of the allergy.
If you have a mild rash, you can wait 2 to 4 weeks before trying it; if you have a more serious rash, such as whole body rash, diarrhea, etc., you can try again after half a year; if it is severe enough to cause anaphylactic shock and difficulty breathing, you should seek medical treatment as soon as possible.
