IgE (or immunoglobulin E) allergies are immediate responses to a foreign substance that has entered the body. These foreign substances can come from food or inhalation.
IgE allergies can cause very serious symptoms like difficulty breathing, swelling, and hives. In even more severe cases IgE reactions can lead to anaphylactic shock. This test measures the blood level of IgE, one of the five subclasses of antibodies. Antibodies are proteins made by the immune system that attack antigens, such as bacteria, viruses, and allergens.
The IgE test is often performed as part of an initial screen for allergies. Symptoms of allergies may include:
- Visible inflammation
- Itchy eyes or nose
- Nasal congestion
- Tight throat
- Trouble breathing.
Symptoms may be seasonal (as with allergies due to pollen or molds) or year-round (as with food allergies), and they can range from mild to severe, depending on the person and the allergy. Symptoms can be particularly harsh for children as their immune systems are not fully formed yet.
Explaining Immunoglobulin G
These are antibodies that provide long-term resistance to infections, called Immunoglobulin G (IgG). They have a much longer half-life (around 28 days) than the traditional IgE allergy.
This is where food sensitivities come in because they are much more subtle and most people live with them for years, if not their entire lives. A food sensitivity is an adverse reaction to a food with no antigen-antibody response.
Symptoms range from headaches and nausea to depression, anxiety, and hyperactivity, or simply just fatigue, bloating, or mood changes after eating.
Dark under-eye circles when you are well-rested also indicate a negative liver response to a food, especially in children.
These symptoms may occur hours or even days after the offending food has been ingested. The degree and severity of symptoms vary widely because of the genetic makeup of the individual.
The complete elimination of IgG-positive foods may bring about substantial improvements health.
Most allergists and doctors only look at the IgE response. As you can see the IgG food sensitivity response, if not considered, can be the cause of serious symptoms as outlined above. It is important to address both.
Kay Spears’ wellness approach for food allergies and food sensitivities is first getting the proper testing. Once she has established what foods needs to be eliminated, she can customize a food plan around those allergies and sensitivities.
Some sensitivities need to be avoided for 8 months, some for only 3 to 6 months. Kay will also be working with you on a specific gut healing protocol that will heal the body and possibly allow you to reintroduce certain foods.
