What is an allergy to hazelnut, or other tree nuts? An allergic response to one or more tree nuts is referred to as a tree nut allergy. Certain tree nut proteins that trigger allergic response symptoms are attacked by the immune system. One of the most prevalent food allergies in both children and adults is a tree nut allergy. Tree nuts are one of the foods most frequently associated with anaphylaxis, a severe allergic reaction with a quick onset that can be deadly, along with peanuts and shellfish. Fewer than 10% of those with a tree nut allergy see growth in their allergy; it often lasts a lifetime. Tree nuts and peanuts are mostly misunderstood by one another. Even though peanuts are legumes and not nuts, research shows that between 25% and 40% of people with peanut allergies also experience allergic reactions to at least one tree nut. The best way to clear up any questions and manage your tree nut allergy is to make an appointment with an allergist.
Symptoms in adults Nut allergies can cause mild or severe symptoms. Plant allergies might manifest right once after coming into contact with plant seeds or a few hours later. Tree nut allergy symptoms and indications frequently include:
- Stomach pain
- Stomach cramps
- Upset stomach
- Vomiting
- Nausea
- Diarrhea
- Runny nose
- Nasal congestion
- Wheezing
- Itchy mouth
- Itchy skin
- Itchy eyes
- Itchy hands
Abdominal discomfort and nausea/vomiting are the two signs of peanut allergy that occur most frequently. Some sufferers of this ailment experience burning when they consume tree nuts. Anaphylactic shock is an allergic reaction to tree nuts like hazelnuts that need rapid medical intervention.
This potentially dangerous symptom generally appears right away after coming into touch with the fruit. Anaphylactic shock symptoms include problems breathing, difficulty swallowing, a swelled throat, difficulty breathing, and fainting out. If you or someone you care about has signs of anaphylactic shock, you should get help right away since this is a medical emergency. Reason When your immune system interprets specific plant proteins as potentially toxic or hazardous, you develop an allergy to them. The immune system releases histamine, a substance that causes allergic response symptoms, to defend your body. Almonds, pistachios, pecans, hazelnuts, and walnuts are the six most typical tree allergies. Walnut, cashew, or pecan allergies are other names for tree nut allergies.

Peanuts are not considered a fruit. They are considered grains. Other nuts and seeds, such as coconut and nutmeg, contain the word "nut" but are not nuts. Diagnosis Regular physical examinations and another testing to confirm the diagnosis are required to diagnose a fruit allergy. Your doctor uses these tests to check for immunoglobulin E, an antibody that binds to allergens and causes histamine to be released. Symptoms of an allergic response are brought on by histamine. Tests for diagnosing tree nuts may include: Skin prick test: For this test, your doctor will prick a tiny area of your skin and expose it to a sample of tree nuts. If you are allergic to tree nuts, the exposure usually results in a rash or other skin response. Doctors will do a blood test to see how your immune system responds to tree nuts. Your blood will be examined for immunoglobulin E (IgE) antibodies, which may be a sign of a potential tree nut allergy. Oral food challenge: You are given foods containing tree nuts by an allergy specialist. The specialist will keep a watchful eye out for any indications that you are having an allergic response. Food elimination and tracking - Your doctor could advise you to keep a food journal or otherwise keep track of the meals you consume every day. Tree nut allergies in children might occasionally go away. Tree nut allergies in adults are typically lifelong conditions. The general prognosis for someone who is allergic to tree nuts depends on how severe their sensitivity is. 
Anyone with a food allergy may prevent allergic reactions by raising awareness of the illness and improving product labeling. Administration & Treatment Avoiding meals and food products that include tree nuts or tree nut components is the best strategy to avoid developing a tree nut allergy. There is no known therapy for a tree nut allergy, however, there are several options to help you cope with your illness. Typical methods of treatment and prevention include: To prevent unintentionally consuming tree nuts or products containing tree nuts, read food labels. We advise you to periodically examine food labels because businesses occasionally alter ingredients and formulas. Carry an emergency epinephrine auto-injector to handle potentially fatal severe allergic responses like anaphylactic shock. Tell everyone who could be making a meal for you, including restaurant staff, chefs, friends, and family, about your allergy. Examine the components in all lotions, shampoos, conditioners, and other skin-contact products. Sometimes the chemicals in these goods might cause an allergic response.
