Milk Allergy in Children
In children, an allergy to cow’s milk can cause abdominal pain, hives and eczema. These symptoms are typically associated with IgE antibodies to milk. Because abdominal pain is also a symptom of lactose intolerance, only your healthcare professional can determine whether your child’s symptoms are caused by an allergic reaction to cow’s milk.
In some children, cow’s milk can lead to a different type of reaction, resulting in colic and sleeplessness, as well as blood in the stool and poor growth. This type of reaction to milk is associated with immune responses that are not related to IgE antibody.
If your child is having any of these symptoms, see your healthcare provider.
