An individual with cashew allergy typically suffers from skin, digestive and respiratory reactions. Even though peanut allergies are more common, cashew allergy poses a higher risk for triggering anaphylaxis which is a severe allergic reaction.

Skin reactions

Once the body is exposed to the allergen, it triggers an allergic response where histamine is released. The initial skin reactions include itchiness or tingling sensation in or around the mouth. These can manifest within minutes after consuming or directly handling cashew or food products that contains cashew.

The skin lesions including hives and inflammation are also common. The reddened, elevated, itchy welts in varying sizes can manifest in a random manner on the skin.

Digestive and respiratory reactions

An individual with cashew allergy might develop asthma or hay fever once the allergens are inhaled or consumed. Other respiratory reactions include the following:

  • Runny or stuffed nose
  • Itchy nose or eyes
  • Itchiness on the roof of the mouth
  • Coughing
  • Wheezing
  • Shortness of breath
  • Chest tightness

As for the digestive reactions, an individual with the allergy can experience the following:

  • Stomach cramping
  • Vomiting
  • Diarrhea
  • Difficulty swallowing
  • Projective vomiting
  • Nausea

Can cashew allergy trigger anaphylaxis?

An individual with cashew allergy is likely to end up with anaphylaxis. The indications of this life-threatening reaction include:

  • Rapid pulse rate
  • Swollen throat
  • Airway constriction
  • Fainting
  • Lightheadedness
  • Loss of consciousness

Remember that ingesting even small amounts of cashew can trigger anaphylaxis. The reaction occurs abruptly and becomes dangerous which is why it is vital to seek immediate treatment.

Considerations

If an individual is allergic to cashew, he/she might also be highly sensitive to pistachios since these are part of the same plant family. Additionally, those who have cashew allergy are likely to be allergic to other tree nuts such as almonds or walnuts.

The signs and symptoms of cashew allergy can be severe and dangerous. A doctor should be consulted for proper assessment and treatment as well as guidance on the foods to be avoided.
