Exercise-induced food allergy

Some people have an allergic reaction to a food which is caused by exercise. If the body is stimulated by exercise, a person with an exercise-induced food allergy May feel itchy and lightheaded.

Oral allergy syndrome

Some fresh vegetables and fruits can lead to a mild allergic reaction that causes the foot to Tingle or itching. This is an example of cross-reactivity, proteins in vegetables and fruits because they cause the reaction ‘re similar to those allergy causing proteins found in certain pollens. For example, if you ‘re allergic to ragweed, you may also react to melons, if you ‘ re allergic to birch pollen, you may also react to apples. Most cooked vegetables and fruits generally do not lead to cross-reactive oral allergy symptoms.

Generally, allergy shots are safe, with minimal side effects. There are no long-term complications associated with this form of therapy, but there is a small risk of allergic reactions immediately following the injection. These allergic reactions can be severe.

Typically, allergy shots may cause slight swelling or redness at the injection site. These reactions can occur immediately after the injection and/or can occur several hours later. This mild allergic reaction is usually harmless and goes away within 24 hours.

The shots may also cause symptoms similar to the allergy symptoms you experience: itchy, stuffy nose; itchy, watery eyes; sneezing. In very rare cases, these symptoms become very severe and are accompanied by other symptoms, including the following, difficulty breathing or wheezing, chest or throat tightness, rapid or irregular heart beat, dizziness or light-headedness, loss of consciousness and death.

This type of very severe allergic reaction is known as anaphylaxis. It is a very uncommon reaction to an allergy shot, but it is dangerous, even life threatening.

This is less likely to happen if you follow the schedule of shots recommended by your allergist and observe the technician administering the shot. Be sure you are receiving the correct dose of the correct extract. The dizziness, light-headedness, and loss of consciousness are due to dangerously low blood pressure, usually called “shock.” These symptoms occur when the brain is not receiving enough blood. Anaphylactic shock is a medical emergency.

Such severe reactions usually begin within 20-30 minutes after receiving the shots. For this reason, most allergists require that you wait in the office for 20-30 minutes after your shots to be monitored. If you should experience these symptoms at any time, tell the allergist or other medical professional right away.

If you have already left the allergist’s office, and are having a severe reaction, go directly to the nearest hospital emergency department. If you already have and Epi-pen, use it. If you have an antihistamine such as Benadryl, take it regardless, go to the nearest hospital emergency room or urgent care center as soon as possible. Do not attempt to drive yourself. If no one is available to drive you immediately, call 911 for emergency transport.

Immunotherapy does not treat symptoms; it treats the immune system, the source of all allergic reactions. Although the exact details of how allergy shots work is unknown, we do know the general way they affect the immune system.

An allergic reaction occurs when the body is exposed to an external substance (the antigen) that the immune system interprets as a foreign invader. In allergic individuals, the immune system then makes an unusual (allergic) response that harms the body.

Allergy shots desensitize you by turning down this immune response to the antigen. As a result of immunotherapy, the white blood cells no longer respond as strongly to the antigen, and less production of the immunoglobulin E antibody to this antigen occurs. So, when you are exposed to this antigen, less severe allergic reactions occur in affected areas like the eyes, nasal mucosal surfaces, and the bronchial airways.
