    A Common Food Allergy

    Peanuts are one of the most common causes of serious allergic reactions. Even small particles of peanuts can be enough to trigger an allergic reaction.

    Who Is Most Likely to Suffer from a Peanut Allergy?

    Children are most likely to suffer from a peanut allergy. Many people see their symptoms become less serious as they get older. Still, an allergy can reoccur.

    People who have been diagnosed with another food allergy are more likely to develop additional allergies than those without food allergies. If food allergies run in the family, your risk for developing an allergy increases.

    People with eczema also tend to develop food allergies.

  • Mild Symptoms of a Peanut Allergy

    Mild Symptoms of a Peanut Allergy

    Typically, an allergic reaction to peanuts will become obvious within minutes of contact.

    Some symptoms can be quite subtle, so learning to recognize them is important.

    Mild symptoms can include:

    • itchy skin
    • hives, which can appear as small spots or large welts
    • an itching or tingling sensation in or around the mouth or throat
    • nausea
    • a runny or congested nose

    Obvious Symptoms of a Peanut Allergy

    Some peanut allergy symptoms can be quite violent and unpleasant. However, they might not represent a serious health risk.

    Some common symptoms include:

    • swollen lips or tongue
    • wheezing
    • diarrhea
    • stomach cramps
    • nausea
    • vomiting
    • swollen face or limbs

    You may also experience a feeling of breathlessness. Due to the distressing nature of the symptoms, a sense of panic is normal.

  • Signs of a Serious Allergic Reaction

    Signs of a Serious Allergic Reaction

    People who suffer from allergies run the risk of anaphylaxis, a potentially fatal condition. In addition to the allergy symptoms previously mentioned, signs of anaphylaxis can include:

    • swollen throat
    • constricted airway
    • severe drop in blood pressure
    • racing pulse
    • confusion
    • feeling dizzy or passing out

    Seek emergency medical help if you or someone you know is suffering from anaphylaxis.

  • What to Do for a Mild Reaction

    What to Do for a Mild Reaction

    A minor allergic reaction is unlikely to be life threatening, but it should still be taken seriously.

    The reaction can usually be treated with over-the-counter antihistamines. These dugs will help relieve symptoms like the sensation of itching or hives. Antihistamines won’t prevent future attacks, so take steps to avoid peanuts.

    Follow up with your doctor if you experience even minor allergic reactions—especially if you haven't been diagnosed with a peanut allergy before.

  • Help! I Think I'm Having a Severe Reaction

    Help! I Think I'm Having a Severe Reaction

    A severe allergic reaction should be treated as a medical emergency. The reaction can be life threatening if the symptoms aren’t treated quickly.

    If you or someone you know is suffering a severe reaction or anaphylaxis, you’ll need an injection of epinephrine (adrenaline). If you don’t have an auto injector, monitor the sufferer's vital signs and general condition until you reach the emergency room.

    Swift action can reduce the severity of symptoms and possible health complications.

  • Peanut Allergy: Foods to Avoid

    Peanut Allergy: Foods to Avoid

    Any product containing peanuts is clearly out of bounds for those with a peanut allergy. However, peanuts or peanut particles can be hiding in some less obvious food sources. If you suffer from a peanut allergy, you may want to cut out these foods entirely or at least take a closer look:

    • takeout food like Chinese, Thai, and Mexican can contain peanuts
    • candy
    • cake and pastries
    • chocolate
    • egg rolls
    • pasta sauce
    • natural and artificial flavorings
    • ice cream and frozen yogurt
    • marzipan

    Living with a Peanut Allergy

    Cut out foods that contain peanuts to help prevent an allergic reaction. Not sharing food is another easy way to reduce allergy risk. Of course, because peanuts are so common, avoiding all contact may be impossible.

    Wearing an allergy alert bracelet can help others take action if you suffer an attack.

    If you have been given medication like antihistamines or an epinephrine autoinjector, carry it at all times to ensure you’re prepared in case of an emergency.
