Allergies Q & A

What are the different types of allergies?

Allergies develop when your immune system mistakenly identifies a substance that’s normally harmless as a dangerous invader. Then every time you encounter that substance, an immune reaction begins, which includes releasing histamines that cause allergy symptoms.

Examples of the most common allergens include:

  • Contact allergens: poison ivy, soap, latex, and other allergens that cause a reaction when they come into contact with your skin
  • Airborne allergens: substances you breathe in, primarily pollen from trees and grasses, mold spores, and dust mites
  • Insect stings: bees, hornets, wasps, yellowjackets, and fire ants are the most common causes of insect allergies
  • Food: most often caused by proteins in cow’s milk, eggs, peanuts, wheat, soy, fish, shellfish, and tree nuts

You can also develop allergies to many medications, but penicillin causes the most allergic reactions.

What symptoms occur during an allergic reaction?

Symptoms vary depending on the type of allergy. For example, hay fever primarily affects your nose and eyes, while contact allergies cause a skin rash or swelling.

The most common allergy symptoms include:

  • Runny or congested nose
  • Sneezing
  • Watery eyes
  • Itchy nose, eyes, or mouth
  • Skin rashes, hives, or swelling
  • Fatigue
  • Headache

Food allergies affect your gastrointestinal system, causing symptoms like an upset stomach, cramps, nausea, vomiting, and diarrhea.

Medication allergies usually cause wheezing, dizziness, and angioedema, which is swelling under your skin.

What is an anaphylactic reaction?

An anaphylactic reaction is a severe, life-threatening allergic reaction. Allergies to food, insects, latex, and medications are the most common cause of anaphylaxis.

The symptoms, which occur quickly and require emergency medical attention, include:

  • Wheezing or difficulty breathing
  • Chest tightness
  • Hives, itching, flushed skin
  • Swollen tongue or throat
  • Dizziness or fainting
  • Nausea and vomiting
  • Blurry vision
  • Confusion

When your allergic reaction includes difficulty breathing or low blood pressure (dizziness, fainting, nausea), you should assume it’s a severe, anaphylactic reaction and immediately use your epinephrine pen or call 9-1-1.

How are allergies diagnosed and treated?

Before determining your treatment, Dr. Yang identifies your specific allergens. He may perform a skin prick test or an allergy blood test, which is sent to a lab for evaluation.

Dr. Yang manages the medications needed to treat your allergy. Depending on the severity of your allergy, you may receive medications like antihistamines to relieve symptoms or immunotherapy to build up your tolerance and diminish or eliminate your allergy.
