How Can I Take Care Of Myself If I Have A Peanut Allergy

Toddler Peanut Allergy Test / Food Challenge & What to Expect?

If you have a peanut allergy, you need to pay close attention to what you eat. Food manufacturers must clearly state on their ingredient label whether a food contains peanuts.

Prepackaged foods that dont contain peanuts can be contaminated during the manufacturing process. Watch for phrases like may contain peanuts and made in a factory on machinery that also may have been used to process peanut products.

When you go out to eat, ask questions about ingredients. For example, peanut butter may be in certain marinades or sauces. Ice cream or yogurt shops could be places of accidental exposure because peanuts are common ice cream toppings.

What Are The Most Common Food Allergens

A child could be allergic to any food, but these eight common allergens account for 90% of all reactions in kids:

  • fish
  • shellfish
  • In general, most kids with food allergies outgrow them. Of those who are allergic to milk, about 80% will eventually outgrow the allergy. About two-thirds with allergies to eggs and about 80% with a wheat or soy allergy will outgrow those by the time they’re 5 years old. Other food allergies may be harder to outgrow.

    What Is A Peanut Allergy

    Peanut allergy is one of the most common IgE-mediated food allergies among children. Nearly 2.5 percent of all children in the United States may have an allergy to peanuts.

    A child with a peanut allergy will show symptoms within minutes to hours of consuming food containing peanuts. Symptoms may include difficulty breathing, nausea, hives

    What Are The Symptoms Of A Nut Allergy

    Both peanuts and tree nuts can cause allergic reactions. Allergic reactions to nuts can vary from mild to very severe, and are sometimes life-threatening. Symptoms often start very quickly, within an hour of having come into contact with a nut, and sometimes within minutes. Reactions that take place more than four hours after coming into contact with nuts are unlikely to be an allergy.

    Signs and symptoms of a mildallergic reaction can include:

    • Your mouth and lips tingling.
    • Your face swelling.
    • Colicky pains in your tummy .
    • A feeling of tightness around your throat.

    Signs and symptoms of a more severeallergic reaction can include:

    • All of the above.
    • Wheezing or difficulty breathing due to an asthma-like attack, or swelling around your throat.
    • A sense of impending doom.
    • Dilation of your blood vessels, which can cause:
    • General redness of your skin.
    • A fast heart rate.
    • Low blood pressure, which can cause you to feel faint or to collapse.

    This severe reaction is called anaphylaxis and without quick treatment you would soon become unconscious. A small number of people die every year as a result of this kind of severe reaction, usually because they do not obtain treatment quickly enough. If you think you are having an anaphylactic reaction you need to call an ambulance straightaway and obtain immediate medical help.

    Treatments For Peanut Allergy

    Once your child is confirmed to have a peanut allergy, the first step in treatment is avoiding peanuts and food containing peanuts or peanut protein.

    Your childs doctor can give you detailed information on how to read food labels to help identify and avoid peanut protein.

    No matter how careful you are, there may be times when your child is accidentally exposed to peanuts and has a reaction. When that happens, you can treat the symptoms with antihistamines or epinephrine.

    If more than one body system is involved in the allergic reaction for example the skin and lungs it is recommended to use epinephrine. Epinephrine comes in a variety of forms, including auto-injectors such as Epi-Pen, Auvi-Q and other generic forms.

    If your childs reaction is mild and only involves a few hives, an over-the-counter or prescription strength antihistamine can ease their symptoms. Your childs doctor can help you decide which option is best for your child, depending on the circumstance and their reaction.

    Children with peanut allergies should carry epinephrine with them, or it should be readily available at places where they routinely spend time, such as school, daycare and home.

    Is There A Cure For Peanut Allergies

    There is no cure for peanut allergies. But children can outgrow peanut allergies. As children get older, an allergist may perform another blood or skin test to measure a childs sensitivity to peanuts. If a peanut allergy appears to be decreasing, allergists may recommend an oral food test.

    There are new treatments available called Oral Immunotherapy and early OIT. This is where carefully selected patients undergo therapy to help develop a tolerance to the food they have an allergy to. Palforzia®, a treatment for peanut allergies, is the first FDA approved treatment for food allergies. Although it doesn’t cure peanut allergies, it can make it possible for people to tolerate accidental peanut exposure without having a reaction.

    If your child has a peanut allergy, it’s important to not give your child peanuts unless an allergist has directed you to do so.

    As an adult, you can manage a peanut allergy by carefully avoiding peanuts. You may need to carry epinephrine if you have severe allergies that could lead to anaphylaxis.

    Start Gradually To Identify Any Food Allergies

    Itâs most important to introduce a baby to new foods gradually, one at a time, in case of food allergies. If not, a parent may have trouble tying an allergy to a specific new food. For example, if you give your baby three new foods over the course of a day and they develop an allergic reaction, you wonât know which of the foods provoked it.

    The type of food or the order in which food is introduced is not much of a concern, as long as the foods you are offering are healthy and well-balanced for the baby. Each time you offer a new food, you should wait three to five days before adding another new item to the menu. Donât eliminate the other foods your baby is eating during that time you already know these are safe because the child has not had any food reactions up until now. Just donât add anything else new.

    How To Tell If Your Baby Is Having An Allergic Reaction

    Peanut allergies in kids

    Food allergy symptoms vary depending on the person, with some being more severe than others. Here are the symptoms of a peanut butter allergy in infants that you should watch for:

    • Topical reactions, such as skin rashes
    • Vomiting and diarrhea
    • Trouble breathing

    If your infant has a peanut butter allergy, your babys skin may become very pale. They could have diarrhea and/or vomiting as their body tries to expel the peanut butter or other food allergen. They may develop hives, or red, splotchy rashes on the skin. Their breathing can change, becoming more restricted as their throat swells. This may be accompanied by wheezing or sneezing.

    Some food allergy sufferers even lose consciousness. If not, lightheadedness can occur, as can circulation issues.

    The most severe reaction to a peanut allergy or other food allergy is anaphylaxis. This is a potentially deadly reaction that impacts heart rate, blood pressure , and breathing. Only epinephrine can treat anaphylaxis, and it should be administered quickly. If youre concerned about a severe reaction to peanut butter in your baby, speak with a physician before feeding your child peanut butter. A doctor can provide the best recommendations on when to introduce peanut butter and how you can prepare for a possible allergic reaction, including anaphylaxis.

    Can You All Of A Sudden Become Allergic To Peanuts

    Yes. Its almost unfair, but its true. While some babies may present allergic reactions at first exposure, starting at just a few months, it turns out that you can develop an allergy at any point in your life. According to Collins, Peanut allergies typically present in childhood but you can present an allergy to peanuts at any point. Thats right. You can develop a peanut allergy at any point in your life.

    Food allergies can develop at any time. But, heres some good news in adults, its very rare. Its actually much more common to suddenly become allergic to shellfish than peanuts. Still, youll want to be on the lookout for any potential symptoms.

    Management Of Peanut Allergy: Medications And Allergy Action Plans

    In the case of a severe allergic reaction adrenaline is the medication needed to treat allergic symptoms and should be given as soon as possible after symptoms of anaphylaxis are recognised.

    Adrenaline autoinjectors, also known as adrenaline pens, are devices that contain the emergency medicine adrenaline that can be given in the case of a severe reaction to peanut. If you or your child are prescribed an adrenaline auto-injector it is important that you are shown how to use it by the doctor, nurse, or pharmacist. These devices are available as trainer pens for the type of adrenaline pen that has been prescribed and are useful for practicing or showing others how to use them .

    Expiry dates should be noted, and reminder services are available from some of the adrenaline pen websites. Adrenaline auto-injectors that have been used or due to expire should be replaced immediately. Allergy medication prescribed for a child with a food allergy should be documented on a written allergy action plan for the childs school or after school clubs or activities. Allergy action plans are individual to the person, listing their food allergies and providing advice on the signs and symptoms of an allergic reaction, as well as instructions on what medication to give and when.

    What Is A Peanut Allergy Test

    According to Collins, there are three ways to test for peanut allergies, specifically for kids. The first is mentioned above small exposures to help kids avoid developing the allergy later. According to Cleveland Clinic, most kids should be exposed to peanuts and other allergens before age 1. Once youre a few weeks into solids, you can mix some peanut butter into your babys purees. You should only do this after youve consulted with your childs pediatrician about the safest way to introduce peanuts to your baby.

    There are two other ways to test for a peanut allergy in a doctors office. One of them is through what doctors call a skin prick test, during which a small amount of the protein is put on the childs arm or back, followed by a prick.

    Then, of course, theres old-fashioned bloodwork. What kid doesnt love to have their blood drawn?! If youre going for this, may we suggest a post-doctor visit treat for parent and child. You can test for allergies through a blood test called the RAST test or immunofluorescence test. The test checks the blood for antibodies that will indicate whether the person has an allergy. Lee notes its important to remember that when it comes to allergy testing, you are only going to see results if the allergy is life-threatening.

    New Guidelines Show How To Introduce Peanut

    Most infants can have at home under supervision

    ARLINGTON HEIGHTS, Ill. The wait is over for parents whove been wanting to know how and when to introduce peanut-containing foods to their infants to prevent peanut allergy. New, from the National Institute of Allergy and Infectious Diseases , published today, define high, moderate and low-risk infants for developing peanut allergy, and how to proceed with introduction based on risk.

    This update to the peanut guidelines offers a lot of promise, says allergist Stephen Tilles, MD, president of the American College of Allergy, Asthma and Immunology . Peanut allergy has literally become an epidemic in recent years, and now we have a clear roadmap to prevent many new cases moving forward. The Learning Early About Peanut allergy study, the study that paved the way for the updated guidelines, has had a dramatic impact on day-to-day patient care. In fact, during my career as an allergist I cannot think of a single publication with more of an impact.

    According to the new guidelines, an infant at high risk of developing peanut allergy is one with severe eczema and/or egg allergy. The guidelines recommend introduction of peanut-containing foods as early as 4-6 months for high-risk infants who have already started solid foods, after determining that it is safe to do so.

    Unpleasant Symptoms Of Peanut Butter Allergy

    Some symptoms of peanut butter allergy may be unpleasant and violent, but not very harmful for your childs overall health. Some symptoms include swollen tongue or lips, diarrhea, wheezing, nausea, vomiting, stomach cramps or swollen limbs or face. Sometimes, the child may experience breathlessness and difficulty breathing. Although these symptoms are harmless, they are distressing and may cause you and your child to panic.

    What Happens In A Food Allergy Reaction

    Food allergy reactions can vary from person to person. Sometimes the same person can react differently at different times. So it’s very important to quickly identify and treat food allergy reactions.

    Reactions can:

    • be very mild and only involve one part of the body, like hives on the skin
    • be more severe and involve more than one part of the body
    • happen within a few minutes or up to 2 hours after contact with the food

    Food allergy reactions can affect any of these four areas of the body:

  • skin: itchy red bumps eczema redness and swelling of the face or extremities itching and swelling of the lips, tongue, or mouth
  • gastrointestinal tract: belly pain, nausea, vomiting, or diarrhea
  • respiratory system: runny or stuffy nose, sneezing, coughing, wheezing, shortness of breath
  • cardiovascular system: lightheadedness or fainting
  • Sometimes, an allergy can cause a severe reaction called anaphylaxis, even if a previous reaction was mild. Anaphylaxis might start with some of the same symptoms as a less severe reaction, but can quickly get worse. The person may have trouble breathing or pass out. More than one part of the body might be involved. If it isn’t treated, anaphylaxis can be life-threatening.

    Dealing With Mild Food Allergies In Baby

    Peanut-allergy prevention in infants – Dr. Maria Garcia-Lloret | UCLA Mattel Children’s Hospital

    If you see mild symptoms, such as hives or a rash, contact your pediatrician for further evaluation. The doctor might refer you to an allergist , who will ask more questions and do a physical exam. The allergies may order diagnostic tests such as:

    • A skin test. This test involves placing liquid extracts of food allergens on your child’s forearm or back, pricking the skin, and waiting to see if reddish raised spots form within 15 minutes. A positive test to a food only shows that your child might be sensitive to that food.
    • Blood tests to check the blood for IgE antibodies to specific foods

    Remember, just because a babyâs initial allergic reaction to a new food may be mild, it may get worse upon following exposures. Talk to your pediatrician about any food allergy symptoms in your baby.

    Some allergies go away with time. Egg and milk allergies often go away as children get older, but peanut, tree nut, and shellfish allergies tend to persist. That said, research shows that in the case of peanut allergies, peanut immunotherapy drops administered under the tongue are safe and effective as treatment for peanut allergy, even in children as young as 1. They were also found to help significantly desensitize the patients to peanuts.
