Nut and Peanut Allergy: Causes and Symptoms


In the intricate dance of the immune system, nut and peanut allergies present a unique challenge. At the heart of these allergies lies the body’s overreaction to certain proteins in foods like peanuts and a range of tree nuts – almonds, Brazil nuts, cashews, hazelnuts, macadamia nuts, pecans, pistachios, and walnuts.

Intriguingly, the molecular dynamics of peanut allergies involve a specific immunoglobulin E (IgE) cross-reactivity, which creates a heightened sensitivity to peanuts and related nuts and legumes.

This immune response can escalate quickly from mild symptoms, such as hives or a runny nose, to severe conditions like impaired breathing or anaphylaxis.

Be prepared for every emergency by completing an accredited first aid training course like HLTAID011. It only takes a few hours to gain a lifetime of benefit.


Navigating the world with nut and peanut allergies requires an awareness of the varied symptoms these allergies can provoke. For those with a peanut allergy, the body’s response might manifest as skin irritations such as hives, itching, or swelling, or as gastrointestinal discomforts, including diarrhea.

In more alarming scenarios, symptoms escalate to compromised breathing, throat swelling, a stark drop in blood pressure, or even fainting and dizziness – all harbingers of anaphylaxis, a severe reaction needing urgent medical attention.

Tree nut allergies mirror these reactions, with symptoms like hives, nasal congestion, cramps, nausea, and difficulty swallowing. Being vigilant and knowledgeable about these signs is crucial for those affected, ensuring prompt and appropriate medical intervention in the face of severe allergic episodes.

Mild to moderate allergic reaction

For a mild to moderate allergic reaction to nuts, the following first aid measures can be taken:

  1. If the symptoms are mild, give an antihistamine by mouth, such as diphenhydramine (Benadryl or a store brand).
  2. Monitor the individual for any worsening of symptoms and be prepared to seek medical attention if the reaction escalates.
  3. If the symptoms persist or get more severe, it’s important to seek medical advice promptly.

It’s crucial to be aware of the potential for the allergic reaction to progress to a severe state, and to be prepared to administer appropriate first aid or to call 000 and seek emergency medical assistance if necessary.

Severe Allergic Reaction

Recognising the Symptoms

Severe allergic reactions to nuts can manifest as anaphylaxis, which is a life-threatening whole-body response to the allergen. Symptoms of anaphylaxis may include:

  • Impaired breathing and/or noisy breathing
  • Wheezing or persistent cough
  • Swelling of the tongue
  • Swelling and/or tightness in the throat
  • Difficulty swallowing
  • Sudden drop in blood pressure
  • Pale or blue-colored skin
  • Fainting or dizziness

It’s important to recognise these symptoms and seek immediate medical attention if a severe allergic reaction is suspected.

What is the Emergency Treatment for Anaphylaxis?

Severe allergic reaction known as Anaphylaxis requires prompt treatment with adrenaline or epinephrine and emergency medical care.

Epinephrine, both a hormone and a neurotransmitter, is essential for the body’s “fight-or-flight” reaction. It is produced by the adrenal glands and is involved in regulating various bodily functions.

In the context of severe allergic reactions, epinephrine is used as a medication to counteract the symptoms of anaphylaxis. It works by relaxing the muscles in the airways, tightening blood vessels, and stimulating the heart, thereby helping to reverse the severe effects of the allergic reaction.

Epinephrine is typically administered via an auto-injector device and is considered a critical first-aid intervention for individuals experiencing anaphylaxis

Emergency First Aid for Severe Allergic Reactions

In the case of a severe allergic reaction, also known as anaphylaxis, immediate emergency first aid is crucial. The following steps should be taken:

  1. Call for Emergency Assistance: Dial emergency services 000, or local medical emergency number immediately.
  2. Administer Epinephrine: If the individual has been prescribed an epinephrine auto-injector, use it as directed. Additional adrenaline doses can be administered if there’s no improvement within 5 minutes.
  3. Lay the Person Down: Help the person lie down on their back and elevate their legs, unless this causes discomfort or injury.
  4. Monitor Breathing: Check the person’s breathing and pulse. Perform CPR if the person becomes unresponsive and stops breathing.
  5. Comfort and Reassure: Stay with the person and provide reassurance while waiting for emergency medical help to arrive

Given the unpredictable nature of allergic reactions, it’s vital to be equipped to handle severe cases. This underscores the importance of CPR training. Enrolling in a course like HLTAID009 can empower you with the skills to effectively respond in emergency situations, including severe allergic reactions.

It is also important to stress again that anaphylaxis is a medical emergency, and prompt treatment is essential for the individual’s safety and well-being.

Avoidance is the only proven treatment for peanut, tree nut or seed allergy

Navigating food allergies with realism and a proactive mindset is key. The cornerstone of managing these allergies lies in avoiding the offending foods such as: peanuts and tree nuts, nut olis, and other foods such as ice cream, cakes and biscuits that may contain traces of nuts. However, despite meticulous efforts, total avoidance can be a tall order.

If you are at at risk of severe allergic reactions, possessing an adrenaline injector, like an EpiPen or Anapen®, is a safety must-have.

Create An Action Plan

The Australasian Society of Clinical Immunology and Allergy (ASCIA), provides an Action Plan that yoy can can tailor to your specific injector type. Even if you are not in the high-risk category, an ASCIA Action Plan for Allergic Reactions is still recommended.

Further empowering yourself involves mastering the art of reading food labels, transforming this skill into a protective shield against accidental allergen exposure.

ASCIA offers invaluable resources, including fact sheets, to guide you through this process, especially pertinent for those with peanut, tree nut, or seed allergies. Check out the following Anaphylaxis Symptoms Chart at the First Aid Pro blog if you or someone you care for has nut allergies.

Remember, adrenaline autoinjectors are also conveniently available over the counter at pharmacies, adding an extra layer of preparedness to your allergy management toolkit.

In addition, always make sure that those around you know that you are allergic to nuts.

In Conclusion

In the managing of nut allergies, knowledge, vigilance, and preparedness are your best allies. This journey through understanding nut and peanut allergies, their causes, symptoms, and the life-saving steps in a crisis, brings us to a crucial juncture – the importance of being prepared for any emergency.

As we close this guide, remember, avoidance remains the primary strategy in managing these allergies. However, the world is unpredictable, and accidental exposures happen. This is where your readiness, backed by comprehensive first aid training like HLTAID012, becomes invaluable. It equips you with the skills to respond effectively to severe allergic reactions, potentially saving a life.
