Food Allergies Q&A

What are food allergies?

Food allergies are your immune system’s overreaction to certain foods or ingredients in foods. When you consume foods that you’re allergic to, your body experiences one or more reactions that range from mild to life-threatening.

These reactions occur because your immune system produces antibodies to fight off a perceived attack against a substance that’s generally considered harmless.

Common triggers of food allergies include:

  • Soy
  • Nuts
  • Dairy
  • Wheat
  • Shellfish

Food allergies are different from a food intolerance, which is a sensitivity to certain foods that doesn’t involve your immune system.

What are the symptoms of a food allergy?

Symptoms of a food allergy typically occur within minutes of consuming a trigger food or beverage. The most common food allergy symptoms include:

  • Hives
  • Vomiting
  • Diarrhea
  • Itchy skin
  • Tingling in the mouth

For some, a side effect of food allergies is a skin condition known as eczema which causes itchy skin patches that may ooze fluid.

You can also experience a life-threatening reaction to certain foods, a condition called anaphylaxis. This condition causes sudden swelling in your throat that causes shortness of breath and wheezing. If not treated properly, anaphylaxis can lead to loss of consciousness and premature death.

How are food allergies diagnosed?

The goal of food allergy testing is to identify the foods that trigger your symptoms, so you’re more prepared to avoid them.

The team at San Antonio Asthma & Allergy offers diagnostic testing through food challenges. This involves a medically supervised procedure where you eat certain foods slowly, in gradually increasing amounts. Testing allows your provider to identify your body’s reaction to certain foods without risking your health.

Once they understand the root cause of your food allergies, your San Antonio Asthma & Allergy provider works with you to make necessary changes to your diet. They focus on creating a diet that ensures you avoid triggers of an allergic reaction without limiting your food choices too much.

The San Antonio Asthma & Allergy team also provides customized treatments for relieving food allergy-related symptoms, including eczema and asthma.
