The Causes of Dairy Allergy
The reason behind the human suffering from any type of allergies is the imbalance of the function of the immune system, where the immune system identifies specific proteins of milk as harmful and thus stimulate the body to produce antibodies (IgE) to offset the protein that causes allergic reactions.
The next time the body is exposed to these proteins, the antibodies recognize it and send a signal to the immune system to produce antihistamines and other chemicals.
The histamine and the other chemicals cause a series of symptoms and signs, but histamine is partially responsible for all body’s responses to the allergens including a runny nose, itching eyes, dry throat, rash, nausea, diarrhea, difficulty in breathing to anaphylaxis which is the severe and dangerous form of allergy.
There are two types of proteins in cow’s milk are causing allergic response:
- Casein: It is found in the curdled part of the milk.
- Whey: which found in the liquid part of the milk and remains after the curd.
The human can be allergic to one or both of them together, and these proteins are not found only in milk, but also in processed foods. In addition, the majority of people who suffer from an allergy to cow’s milk suffer similarly from the same sensitivity from buffalo milk, sheep and goats, and less in common than soy milk.
The factors that increase the possibility to suffer from dairy allergy:
- Other types of allergies: If your child is allergic to milk he will suffer from other types of sensitivity because the sensitivity of dairy is of the first sensitivities that affect the human.
- Family history: If both parents or one of them is suffering from allergic reactions to some foods or any other type of allergies such as Hay Fever, Asthma or The possibility of suffering from a Dairy allergy will increase.
- Age: the dairy allergy is common among children, and when the child grows up in age and with the maturity of his digestive system, it will appear less responsive when exposed to dairies.
- Skin allergies (Atopic dermatitis): Children who have sensitive skin, increasing to them the risks of suffering from an allergy to some foods such as dairy.
Children who suffer from dairy allergy are more susceptible to some other complications and health disorders, like:
- The sensitivity of other foods such as eggs, soy, peanuts or even meat.
- The incidence of hay fever, which is an immune system response against the pets that are bred, dust mite or grass vaccines and any other substances.
