What are the symptoms of a tree nut allergy?

If you’re allergic to tree nuts and exposed to them, you may develop symptoms of an allergic reaction. In some cases, these symptoms will appear within minutes and be severe. In other cases, it may take 30 minutes to a few hours before symptoms begin.

Symptoms of a tree nut allergy may include:

  • abdominal pain, including cramping and upset stomach
  • nausea and/or vomiting
  • diarrhea
  • trouble swallowing
  • itching of the mouth, throat, skin, eyes, hands, or other body regions
  • shortness of breath and difficulty breathing
  • wheezing
  • nasal congestion or runny nose
  • Anaphylaxis

Anaphylaxis is rare, but it’s the most severe form of allergic response. In the case of anaphylaxis, a person with an allergy will typically begin experiencing symptoms within 5 to 30 minutes of exposure to the tree nut. Symptoms of anaphylaxis include:

  • swollen throat
  • wheezing
  • passing out
  • trouble swallowing
  • vomiting
  • a red rash with hives or welts

Peanut, shellfish, and tree nut allergies are among the most common causes of anaphylaxis. People with a severe tree nut allergy should always be prepared to respond to an allergic reaction. You should always keep an epinephrine auto-injector with you.
