Tree nut hypersensitivities refer to allergic reactions or hypersensitivity reactions that occur when an individual is exposed to tree nuts, such as almonds, walnuts, cashews, pistachios, or hazelnuts.
These allergic reactions are caused by the immune system mistakenly identifying proteins present in tree nuts as harmful and triggering an immune response. The immune system then releases chemicals, such as histamine, into the bloodstream, leading to the symptoms of an allergic reaction.
Common symptoms of tree nut hypersensitivities include itching, hives, swelling of the lips, tongue, or throat, difficulty breathing, abdominal pain, nausea, vomiting, or in severe cases, anaphylaxis, which is a life-threatening allergic reaction.
Tree nut allergies are classified as one of the most common food allergies, and they tend to persist throughout an individual's lifetime. Therefore, it is essential for individuals with tree nut hypersensitivities to strictly avoid consuming tree nuts and their products.
In case of accidental exposure or ingestion, individuals who are aware of their allergy should carry an epinephrine auto-injector, commonly known as an EpiPen, which can be used to quickly treat anaphylactic reactions.
It is important to note that tree nut hypersensitivities are different from peanut allergies, as peanuts are legumes and not tree nuts. However, individuals with tree nut allergies may also have cross-reactivity to peanuts, meaning they may experience allergic reactions to peanuts as well. Therefore, it is advisable for individuals with tree nut hypersensitivities to avoid peanuts and their products too.
