Allergen,Individual-FoodCow MilkDoodh

Milk is known for being a commonly encountered allergy, the culprit being the proteins (whey and casein) in the milk. Although milk allergies mainly occur in young children, they can emerge at any age. An allergic reaction may even be caused by foods containing milk consumed previously without any problems.

A milk allergy is triggered by a reaction in an individual's immune system. The body views certain substances as toxic and produces IgE antibodies to these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.

It is essential for individuals not to confuse a milk allergy with lactose intolerance. Lactose intolerance is not an allergic reaction and does not involve the immune system. Lactose intolerance is when the body cannot digest lactose, the sugar in dairy products. Symptoms of lactose intolerance include gas, stomach pain, and diarrhea. However, for individuals with a milk allergy, the symptoms affect more than just the digestive tract.
