Allergies Q&A

What are allergies?

Allergies are your body’s overreaction to certain substances, not generally considered harmful to others. When you come into contact with triggering substances in your environment or eat certain foods, your body produces antibodies in its own defense to fight off a perceived attack. These antibodies are what cause a variety of symptoms, some serious enough to interfere with your quality of life.

Common allergy triggers include:

  • Mold
  • Dust
  • Pollen
  • Insect bites
  • Pet dander
  • Certain medications

Any type of food can trigger food allergies, but the most common triggers for food allergies involve dairy, shellfish, wheat, nuts, and soy.

What are the symptoms of allergies?

Allergy symptoms can range from mild to severe and affect each person differently. For many people allergic to environmental substances, like pollen or pet dander, symptoms typically include:

  • Coughing
  • Sneezing
  • Itchy, watery eyes
  • Stuffy or runny nose
  • Skin irritation or hives

You can also experience shortness of breath, especially if you have existing asthma.

If you have allergies to certain foods, you may experience gastrointestinal issues, like persistent vomiting and stomach cramps.

Any type of allergy can also produce a life-threatening reaction known as anaphylaxis. Anaphylaxis is a condition where sudden throat swelling occurs after contact with an allergen that makes it difficult to breathe and can lead to a loss of consciousness without immediate treatment.

How are allergies diagnosed?

Your San Antonio Asthma & Allergy specialist can recommend one or more on-site diagnostic tests to confirm that your symptoms relate to an allergy and determine what your allergy triggers are.

These tests include:

Skin patch testing

Skin patch testing involves pricking your skin with a small amount of a suspected allergen to stimulate a reaction and confirm or rule out an allergy trigger.

Subcutaneous testing

Subcutaneous testing is similar to skin patch testing, except the allergist uses a small, thin needle to inject suspected allergens under the surface of the skin.

Blood and serology testing

Blood testing shows the presence of antibodies in the blood triggered by exposure to certain allergens, specifically the human immunoglobulin (IgE), that confirms an allergy.

How are allergies treated?

The allergy team at San Antonio Asthma & Allergy can recommend over-the-counter and prescription medications to treat and prevent mild and seasonal allergy symptoms.

The San Antonio Asthma & Allergy team also offers immunotherapy to control moderate to serious symptoms of allergies. The goal of immunotherapy is to continually expose your immune system to confirmed allergens to change how your body reacts to them. Over time, immunotherapy can eliminate allergic reactions and prevent new ones from developing.
