Can you be deathly allergic to mushrooms?

Allergies to mushrooms are unlikely. The most common cause of mushroom allergies is cross-reactivity. This happens when a person who is allergic to one type of fungus has an allergic reaction to a different type of fungus.

If you’re allergic to a type of fungus that grows on shiitake mushrooms, you’re more likely to be allergic to shiitake mushrooms.

Why does a certain type of fungus cause an allergic reaction?

Fungi produce a compound called triterpenoid. This compound has been linked to allergies in some people.

Some types of fungus contain triterpenoids. These compounds are also present in many other types of fungi.

For some people, triterpenoids trigger an allergic reaction. This is called cross-reactivity.

Cross-reactive allergens can cause symptoms like:

  • Itching
  • Hives
  • Skin rash
  • Hives-like symptoms
  • Swelling of the eyes, lips, or tongue
  • Wheal and flare reaction, which is a localized inflammation

Diagnosis

If you’re experiencing an allergic reaction to mushrooms, you should see your allergist to determine what exactly is causing your symptoms.

Other causes of an allergic reaction to mushrooms can include:

  • Chemical sensitivities
  • Medications
  • Food allergies
  • Bee stings
  • Insect stings
  • Poison ivy

Your allergist will check your medical history and discuss any possible allergies. They may also perform a skin test to check for cross-reactivity with mushrooms.

In a skin test, a small amount of a substance that causes a reaction is applied to your skin. If you’re allergic to the substance, you’ll likely have a reaction. If you aren’t allergic to the substance, you won’t have a reaction.

Your allergist may also perform a blood test to check for allergies.

Treating the symptoms

If you have a mushroom allergy, you should avoid consuming mushrooms and any other foods that contain triterpenoids.

You can also use medications to treat your symptoms.

Some people with mushroom allergies develop anaphylaxis. Anaphylaxis is a severe allergic reaction. It can cause:

  • Difficulty breathing
  • Swelling of the throat, tongue, or lips
  • Flushed face
  • Low blood pressure

If you’re having an anaphylaxis reaction, you should seek emergency medical attention.

Treatment of anaphylaxis includes:

  • Epinephrine. Epinephrine is a medication that can stop a severe allergic reaction.
  • An antihistamine. An antihistamine can help relieve itching or swelling.
  • Steroids. Your doctor may prescribe steroids if you’re experiencing severe symptoms.

If you experience a severe allergic reaction, you should seek emergency medical treatment.
