Team AckoMay 11, 2023

Tree nut allergies are incredibly dangerous, and often life-threatening. However, with the right information, people who suffer from them can still lead happy, healthy lives. In this comprehensive guide, you’ll learn the causes, symptoms, diagnosis, treatments, and prevention of tree nut allergies in India.



What is a Tree Nut Allergy?

A tree nut allergy is an adverse reaction caused by the body’s immune system reacting to a harmless nut or nut product. The most common tree nuts in India are almonds, cashews, pistachios, walnuts, and hazelnuts. It is important to note that a tree nut allergy is separate from peanut allergies, as the body reacts differently to peptide sequences in each type of nut. Those with tree nut allergies will experience symptoms after eating, touching, or even inhaling the causative agent. Symptoms can range from mild to life-threatening.

Causes of Tree Nut Allergy

While the exact cause of a tree nut allergy is unknown, it is believed to be an inherited condition, or caused by increased exposure to foods containing tree nuts. Allergens from tree nuts are present in everything from pastries to cosmetics, and can easily be transferred from one item to another. By understanding the sources of these allergens, people with tree nut allergies can take necessary precautionary measures to avoid contact.

Symptoms of Tree Nut Allergy

Common symptoms of a tree nut allergy can be physical or psychological. These include hives, itching, stomach cramps, vomiting, a tingling sensation in the throat, difficulty breathing, dizziness, and anxiety. If a reaction is severe, anaphylaxis can occur, which is a life-threatening emergency. Signs of anaphylaxis include swelling of the face, tongue, throat, and hands, as well as difficulty breathing, fainting, and a drop in blood pressure.

Diagnosing Tree Nut Allergy

Tree nut allergies can be difficult to diagnose because it varies from person to person. Allergy tests can help diagnose a tree nut allergy, and the results from tests can distinguish an allergy from food intolerance. A skin prick test or an oral food challenge can be used to determine if a person is allergic to tree nuts. It is important to consult with an allergist before undergoing any of these tests.

Treatments for Tree Nut Allergies

Treatment for tree nut allergies depends on the severity of the reaction. For mild reactions, an antihistamine can be used to treat the symptoms. Those with more severe reactions should carry an epinephrine auto-injector in case of anaphylaxis. Additionally, those with tree nut allergies should always make sure to read food labels and ask restaurant staff about ingredients when eating out.

Preventing a Tree Nut Allergy

Unfortunately, there is no surefire way to prevent an allergy to tree nuts. However, those with an existing allergy can take the following steps to avoid triggers: read food labels carefully, carry an epinephrine auto-injector with you at all times, and avoid contact with environments where airborne particles from nuts may be present.


Tree nut allergies can be incredibly serious, so it’s important to be educated on their causes, symptoms, diagnosis, treatments, and preventive measures. If you suspect that you or someone you know may have a tree nut allergy, it’s important to consult with an allergist to rule out a food intolerance. With the right information, those with tree nut allergies can still maintain safe and healthy lifestyles.
