Immunoglobulin E is one of the antibodies in the immune system. Food allergies are triggered by the production of this substance is a type of food allergy is the most common and the usual symptoms will appear shortly after the patient ate.

As for the meal, allergies are triggered by substances other than the antibody immunoglobulin , a span of symptoms will require a longer time or the usual hours after the patient ate.

The latter type of food allergy is a combination of immunoglobulin E and non-immunoglobulin People suffering from this condition will experience symptoms of both types of allergies such foods.

Symptoms of Food Allergy

In the case of food allergies on - immunoglobulin , the main symptom that arises is actually almost the same as the symptoms of food allergy mediated by substancesimmunogbulin , namely the emergence of itching and skin rashes. But the difference, texture rash on the type of allergy does not seem to arise. In addition, there are experiencing symptoms such as atopic eczema, which is when the skin looks dry and cracked, red, and itchy.

Sometimes food allergies on - immunoglobulin E can bring the same symptoms as caused by other conditions. This means it can be difficult to distinguish the causes and the symptoms can not be deemed as allergic reactions. These symptoms include:

  • Genital area and the anus appear reddish.

  • Indigestion .

Allergies result from nuts commonly experienced by children. Besides nuts, children can also experience the allergic reaction after consuming milk, eggs, wheat, and soybeans. Milk allergy in children often causes symptoms mixture is in the allergic immunoglobulin E and not-immunoglobulin , which is swelling and constipation.

Factors Enhancing Food Allergy Risk

If you suffer from allergies other than food allergies, then your chances of developing allergies to foods are greater than those who have never had any allergies. Additionally, if you have a history of asthma, the risk of food allergies is also higher because both of these conditions tends to arise simultaneously.

If during this period you will no longer have an allergic reaction, but instead re-experienced after the food consumed again, then you are suffering from a food allergy positive.

Blood tests and skin prick test is usually performed on patients suspected of having a food allergy mediated substance immunoglobulin , that is when the symptoms develop very quickly. While the food elimination test is usually performed in cases of food allergies non-immunoglobulin , which is when symptoms develop slowly.
