What does dairy allergy involve?

ANSWER

Dairy allergy involves the immune system. If you have it, your body reacts to the proteins in milk and other dairy products as if they’re dangerous invaders. It releases substances that cause allergy symptoms. This allergic reaction can be mild (rashes) to severe (trouble breathing, loss of consciousness).

Dairy allergy is one of most common allergies, especially in children. As many as 2 in every 100 children under 4 years old are allergic to milk. It’s even more common in babies.
