What is a Milk Allergy?
Cow’s milk allergy is one of the most common food allergies in infants and adults, but not many people know what causes it or how it shows. Milk allergy is sometimes confused with lactose intolerance, but while these conditions are both triggered by consuming dairy products, they don’t share the same causes or symptoms. They also require different treatments.
If someone has a milk allergy, their immune system considers certain proteins in cow’s milk as invaders. In order to neutralize this perceived danger, it initiates a potentially life-threatening allergic reaction. Lactose intolerance, on the other hand, is rooted in problems with breaking down and digesting lactose, which is the main sugar found in dairy products.
As milk allergy tends to manifest in infancy, knowing how to recognize the symptoms early on is important for parents and careers. We’ve created a guide to milk allergy to help you have a better understanding of the causes, symptoms and treatment options for this common condition.
According to the National Institute for Health and Care Excellence, milk allergy is an immune-mediated allergic response to one or more proteins in cow's milk, such as casein and whey. There are three different types of milk allergy, depending on the under lying immune mechanism and timing of symptoms: (Ig)E-mediated, mixed IgE and non-IgE mediated.
An immunoglobulin(Ig)E-mediated allergy happens when a person starts producing serum-specific IgE antibodies immediately after being exposed to trigger proteins. This type of milk allergy produces instant and consistently reproducible symptoms. Adverse reactions typically occur up to two hours after eating dairy products, but usually within 20–30 minutes.
A non-IgE-mediated food allergy does not involve the production of specific antibodies and reactions to this type of milk allergy are typically delayed. They usually manifest between two and 72 hours after the ingestion of cow’s milk. Mixed IgE and non-IgE allergic reactions involve a combination of IgE and non-IgE responses and are usually delayed.

Which statement best explains why a milk allergy is different from lactose intolerance?
Lactose intolerance causes an immune system reaction, while a milk allergy affects digestion.
A milk allergy only affects infants, while lactose intolerance affects only adults.
Both conditions cause the same symptoms but have different triggers.
A milk allergy is an immune system reaction, while lactose intolerance is a digestive issue.

Why is it important for parents and caregivers to recognize milk allergy symptoms early in infants?
Early recognition helps prevent complications.
Milk allergy symptoms always worsen over time if not treated.
Identifying a milk allergy early prevents all future allergic reactions.
Delayed diagnosis means the child will never outgrow the allergy.
