Allergies Q & A

What causes allergies?

Allergies are the result of your body’s immune system reacting to harmless substances. When you come into contact with such substances -- or allergens -- your body produces IgE proteins (antibodies), which subsequently triggers allergy symptoms.

Typical allergens include:

  • Grass and weeds
  • Tree pollen
  • Molds
  • Animal dander
  • Food
  • Medications
  • Dust mites

How do you diagnose allergies?

Dr. Feliz-Cruz provides environmental and food allergy testing at her clinic. She can pinpoint your allergy triggers through skin or blood testing.

During an allergy skin test, Dr. Feliz-Cruz exposes your skin to a variety of common allergens and monitors the reaction. If your skin reacts to a certain substance, she can conclude that you’re allergic to it.

Dr. Feliz-Cruz uses blood tests to determine if certain allergens trigger antibodies in your body. If antibodies are present, you have an allergy to the allergen in question.

When should I see a doctor?

If your symptoms are mild and tolerable, you can control them without intervention or with over-the-counter medications. If your symptoms worsen, make you uncomfortable, or interfere with your daily life, you can make an appointment with Dr. Feliz-Cruz to find relief.

If you have severe allergies that trigger anaphylaxis or you have another health condition that worsens with allergies, consult with Dr. Feliz-Cruz right away.

What treatment options are available for allergies?

Patients with severe anaphylactic reactions usually get an EpiPen® to carry with them. They must administer epinephrine injections to themselves to prevent life-threatening side effects.

Certain allergy medications help ease the bothersome symptoms. Dr. Feliz-Cruz may have you try over-the-counter or prescription-strength antihistamines, decongestants, or corticosteroids. Most cell stabilizers in eye drops and nasal sprays help reduce inflammation.

Immunotherapy is effective for some people. This allergy treatment involves allergy shots to increase your tolerance to allergens.

For those with certain food and environmental allergies, treatment may involve eliminating the allergens from their diet or living space. Other non-drug approaches may help as well, including:

  • Acupuncture
  • Allergy-proofing your home (such as with special pillow covers or HEPA air filters)
  • Probiotics and supplements
  • Saline spray


If you suffer from allergies, come in to see Dr. Feliz-Cruz to identify your triggers and get proper treatment.
