Cow's milk allergy: description

Those affected by cow's milk allergy (KMA) are allergic to proteins (proteins) found in cow's milk. Milk proteins of other mammals, such as goats or mare's milk, can cause allergies.

To facilitate understanding: An allergy is an overreaction of the body's defense system. The immune system is directed against so-called allergens. These substances are found in nature, can consist of vegetable or animal proteins and are normally harmless. But the immune system of an allergic person misjudges her and fights her. This is noticeable by the allergic reaction. If the immune system reacts a person allergic to a substance, it is said to be "sensitized" to this allergen.

Cow's milk allergy is the most common allergy in children under the age of three. Overall, about two to three percent of the population are affected. It usually begins in the first few months after breast milk has been replaced by milk powder. Often, the KMA ends at the age of three. Only a few adults are affected by it.

It is important to distinguish between cow's milk allergy and lactose intolerance. Cow's milk allergy occurs less frequently and is characterized by a reaction of the immune system to cow's milk proteins. In the case of lactose intolerance, those affected lack the enzyme that breaks down the milk sugar, lactose. They often suffer from bloating or diarrhea after eating milk.
