食物过敏|概述

What is a food allergy?

食物过敏是对某种食物的异常反应。如果您的孩子对食物过敏,则暴露于该食物会导致免疫系统反应,从而导致症状从不舒服到威胁生命。通常,一个allergic reactionwill occur the second time your child is exposed to a particular food. However, in some cases, your child could be sensitized to a food through breast milk.

百分之九十的食物过敏是由以下六种食物引起的:牛奶,鸡蛋,小麦,大豆,树坚果和花生。6岁以下的儿童中有8%的食物过敏。

What are the symptoms of a food allergy?

Symptoms may begin anywhere from a few minutes to an hour after your child ingests the food. Common symptoms include:

  • vomiting
  • diarrhea
  • cramps
  • 麻疹
  • 肿胀或皮疹
  • eczema
  • itching or swelling of the lips, tongue, or mouth
  • 喉咙发痒或紧绷
  • difficulty breathing
  • wheezing
  • lowered blood pressure

The symptoms can be different for milk allergies and soy allergies, which are often seen in infants and young children. The symptoms may include:

如果怀疑牛奶过敏,您的医生可能会将婴儿的配方更改为大豆配方。如果您的宝宝在大豆配方奶中有问题,则您的孩子的医生可能会建议使用低过敏性配方奶粉。

许多孩子确实过敏,但是对花生,坚果,鱼和贝类的过敏可能会持续一生。

What causes food allergies?

A food allergy occurs when the body's immune system identifies a food as harmful, triggering an allergic reaction. According to theNational Institute of Allergy and Infectious Diseases, even a small amount of the food can cause a severe reaction in a highly allergic child.

How we care for food allergies

At Boston Children’s Hospital, our allergists provide diagnostic evaluations for food allergies that are supported by our advanced allergy testing facilities. Once an allergy is diagnosed, our allergists create an individual treatment plan for each child. Treatment may include education, medical management, and coordinated care with your child’s primary physician.

食物过敏诊断接头是如何nosed?

The first step to diagnosing a food allergy is a complete medical history. The allergist will perform a physical exam and ask questions about your child's symptoms to see if they are related to a food allergy. The allergist may do a series of tests to help identify a food allergy. The results will be reviewed along with your child's medical history to provide a diagnosis.

To help diagnose a food allergy, your allergist may recommend:

  • 完成您每天吃的所有食物的食物日记
  • 皮肤刺测试
  • trying an elimination diet to cut certain foods from the diet, then slowly adding them back in one at a time to try to pinpoint the allergy
  • 血液检查

How are food allergies treated?

There is no medication to prevent a food allergy. The best way to avoid an allergic reaction is for your child to avoid the foods that cause the allergy. If you are breastfeeding, you must also avoid those foods. In some cases, your allergist may have you introduce a food back into your child’s diet after a few months, to see if they have outgrown the allergy.

If your child’s allergy is severe, the allergist may prescribe an emergency kit that contains epinephrine. This is a medicine that immediately stops the symptoms of a life-threatening reaction.
