The cause or reason for developing milk allergy is the immune system malfunctioning. That means your immune system identifies some milk protein as inappropriate or harmful for you. So next time when you drink such milk your immune system triggers for the secretion of immunoglobulin E or IgE antibodies which neutralizes the protein which causes to develop signs or symptoms of milk allergy.

In cow’s milk, there are two primary proteins that can cause an allergic reaction by releasing histamine and some other chemicals through your immune system. Those milk proteins are as follows:

  • Whey: Whey protein exists in the liquid part of the milk which remains after the milk curdles.
  • Casein: Casein protein exists in the solid part of milk which curdles.

The milk allergy patient can get the allergy trigger by either one or both types of milk protein which vary from person to person.
