Overview
Milk allergy is an atypical immune system response to milk and products containing milk. It's one of the most common food allergies in children, and it's estimated that 2.5% of children under the age of three are affected by it (1). Cow's milk is the usual cause of milk allergy, but milk from sheep, goats, buffalo, and other mammals can also cause a reaction.
Types of Milk allergy
There are several types of milk allergy, including:
- Cow's Milk Allergy: This is the most common type of milk allergy, and it's caused by an immune response to one of the proteins in cow's milk.
- Goat's Milk Allergy: Some people may be allergic to goat's milk, which is often used as a substitute for cow's milk.
- Sheep's Milk Allergy: Sheep's milk can also cause an allergic reaction in some people.
- Buffalo's Milk Allergy: Buffalo's milk is another type of milk that can cause an allergic reaction.
Causes of Milk allergy
The exact cause of milk allergy is not yet fully understood, but it's believed to be an immune system response to one of the proteins in milk. The proteins in milk are:
- Casein: This is the main protein in cow's milk.
- Whey: This is another protein in cow's milk.
Risk Factors of Milk allergy
Several risk factors may increase the likelihood of developing a milk allergy. These risk factors include:
- Family History: If there is a family history of allergies or atopic diseases, such as asthma or eczema, the risk of developing a milk allergy may be increased.
- Genetics: Genetic factors may also play a role in the development of a milk allergy.
- Age: The risk of developing a milk allergy is highest in infants and young children.
- Environmental Factors: Exposure to certain environmental factors, such as pesticides or heavy metals, may increase the risk of developing a milk allergy.
