Can You Develop Peanut Allergy

Feeding children peanuts may avoid allergies in later life

It is possible to develop a tree nut allergy as an adult.

Most food allergies start in childhood, but they can also develop in adults.

It is unknown why some adults develop an allergy to a food they have previously consumed without problems.

Tree nuts can cause severe, potentially fatal, allergic reactions.

Food Allergy: A Breakdown Of Or Delay In Food Tolerance

Regardless of when it develops, a food allergy results from a breakdown in tolerance, or a delayed development in tolerance, of the proteins in a certain food. And although some food allergies are outgrown, once a food allergy develops, there is no cure.

A child may develop a food allergy because their body hasn’t yet developed a tolerance to a food protein, but then may “outgrow” the allergy and build up a tolerance to that food.

Conversely, a child or adult may tolerate a food at first , but then develop an allergy to that food because their tolerance of that food breaks down. For example, someone may eat shellfish without any issues for years, but then develop a shellfish allergy in their 30s because their tolerance to shellfish breaks down.

Someone’s body may also never build up tolerance to a food after it breaks down or is delayed. If this happens, they’ll have a food allergy for the rest of their life.

Does A Peanut Allergy Get Progressively Worse

Each year, many adults and children in Atlanta experience their first allergic reaction after consuming peanuts. In many cases, these individuals cope with their uncomfortable symptoms without seeking an effective peanut allergy treatment plan. While food allergies may be mild, it can be incredibly risky to leave an allergy undiagnosed. But do peanut allergies get worse with each exposure?

Living With A Food Allergy

The only way to manage a food allergy is to avoid the allergen. Sounds simple, right? Actually, living with a food allergy can be complicated and challenging. Your allergen could be an ingredient in foods you would never imagine finding it in.

“Even after I had my first reaction to shrimp, I was taking chondroitin and krill oil. No wonder I was still getting mild random hives, Adkins says. Chondroitin, a supplement people take for joint pain and osteoarthritis, contains glucosamine, which is made of shellfish.

Eating out requires careful thought and questioning. “When going to dinner you have to tell people they just don’t think to ask, Adkins says. You have to think about the salt and pepper shakers in seafood restaurants. People handle them with fishy hands. Many Asian condiments have shellfish. Buffets are a nightmare.”

Here are some helpful tips for managing your food allergy:

  • Read the ingredient list on all foods.
  • Avoid cross-contamination if others in your home continue to eat the allergen. Don’t share the same unwashed cutting board, for example.
  • Be clear with restaurant staff and verify that they can prepare your food allergen-free.
  • Alert family and friends so food you consume from them is allergen-free.
  • Don’t cheat! Even one bite of your allergen can be life-threatening.

Allergies Are An Immune System Response

Can You Get Allergies Later In Life

When you have a food allergy, your immune system mistakenly identifies components in your food as dangerous and attacks them with histamines. Your body may respond with symptoms like hives, itchy skin, vomiting, dizziness, swelling, and difficulty breathing. In the worst cases, sufferers can go into anaphylactic shock, which can be life-threatening if not treated immediately.

Food Allergy Symptoms In Adults

If you think you might be developing a food allergy, keep an eye out for the following after you eat:

  • Stomach pain
  • An itchy mouth or throat
  • Shortness of breath

All of these symptoms could be a sign of a food allergy.

While none of these symptoms are pleasant, they could be the least of your food allergy worries. If your allergy is severe, it can send you into anaphylaxis, which is a life-threatening allergic reaction. If you have serious trouble breathing and experience dizziness right after eating, dont wait for an allergy diagnosis. Call 911 or go to the nearest emergency room. It could save your life. We can handle the exact diagnosis when you are out of danger.

Next Steps In Peanut Allergy Treatments

Ongoing treatment programs aim to refine the treatment process that grew from the LEAP study, says Dr. Hong. More than 50 children with an identified peanut allergy are in the program.

The minimal goal is to help these children achieve at least bite-proof tolerance to peanuts, meaning they can consume nearly two peanut kernels without a reaction, says Dr. Hong. That protects against an accidental nibble of a food with peanuts leading to a health emergency.

Many participants, however, see their immune system response change so much that they can eat peanut products, says Dr. Hong.

The key is the age of the participants, as reactions to food allergens typically are less severe in early childhood. Their immune system is so malleable, so flexible, that they can tolerate it, notes Dr. Hong. There is this narrow window where we can do this.

The series of peanut challenges given to participants involve tiny amounts of the food. In the initial treatment cycle, for example, the daily dose is 8 milligrams of peanut protein.

Small increases follow every two weeks if there are no setbacks, says Dr. Hong. The process takes at four to six months, with maintenance dosing then continuing for at least a year.

Every uptick in peanut butter dosage takes place in an allergists office in case theres a reaction. The child is monitored for an hour after the higher dose.

What Are The Signs & Symptoms Of A Nut Allergy

When someone with a peanut or tree nut allergy has something with nuts in it, the body releases chemicals like histamine .

This can cause symptoms such as:

  • wheezing
  • a drop in blood pressure
  • dizziness or fainting
  • anxiety or a feeling something bad is happening

Reactions to foods, like peanuts and tree nuts, can be different. It all depends on the person and sometimes the same person can react differently at different times.

In the most serious cases, a nut or peanut allergy can cause anaphylaxis . Anaphylaxis is a sudden, life-threatening allergic reaction. A person’s blood pressure can drop, breathing tubes can narrow, and the tongue can swell.

People at risk for this kind of a reaction have to be very careful and need a plan for handling emergencies, when they might need to use special medicine to stop these symptoms from getting worse.

Nearly Half Of All People With Food Allergies Develop Them As Adults

New Research Shows More Adults Developing Peanut Allergies

While the number of adults with food allergies is relatively low, almost half of them developed their allergies after childhood. In this article, we explain the basics of food allergies and discuss what you should do if you suffer an allergic reaction.

Did you know that you can develop food allergies no matter how old you are? Many of us assume that once we reach adulthood, were safe from new food allergies. Unfortunately, this isnt true: studies show that almost half of adults with diagnosed food allergies developed them later in life.

However, many of us with suspected food allergies really have other conditions like food sensitivities. Keep reading to learn more about food allergies, food sensitivities, and the warning signs of an adult-onset allergy.

Food Allergies Can Develop During Adulthood

Many of us associate food allergies with childhood, but a recent study reports that more than 48% of people with food allergies develop them as adults. Even more worrisome is the fact that more than 51% of adults with food allergies will at some point experience a severe reaction that requires medical care.

Because food allergies can develop suddenly, you need to take symptoms like facial swelling, hives, and dizziness seriously. This is especially true if those reactions occur when youre eating foods that commonly trigger allergies such as shellfish, milk, peanuts, and tree nuts. And if you suddenly have difficulty breathing or swallowing, dont wait go to the nearest emergency room and get help immediately.

Tree Nuts And Related Allergies

can you develop allergies later in life

Keep in mind that a sudden walnut allergy may also mean that you’ll have a sudden allergy to almonds and other tree nuts. You may also have a sudden peanut allergy, despite the fact that peanuts are a legume rather than a tree nut. You might even develop an allergy to pollen or something else that is seemingly unrelated.

This is due to cross-reactivity. According to a June 2015 study in the World Journal of Methodology, cross-reactivity occurs when your immune system has a response to similar allergenic molecules.

Closely related species, like different nuts within the tree nut family, can consequently induce the same type of allergic response. Cross-reactivity can also occur when two unrelated species share a similar protein structure. For instance, 70 percent of people who are allergic to birch pollen are also allergic to nuts, especially hazelnuts.

Because tree nut allergies can be very serious and even deadly, the American College of Allergy, Asthma and Immunology, World Journal of Methodology and the Mayo Clinic all recommend avoiding these foods if you’ve discovered you’re allergic to them. If you suspect a sudden tree nut allergy, you should talk to your doctor.

If you’ve developed a sudden walnut allergy but aren’t sure if you’re allergic to other tree nuts, your allergist can help you determine which nuts you can safely eat or need to avoid. The doctor will also be able to help you determine any cross-reactive allergies you may have.

How To Know What Youre Allergic To

Since it takes a while for the allergy to build up and hammer you, it can take a while to track down whats driving it. You dont have to know exactly which grass or tree is your nemesisdosing up with OTC allergy medication can usually squelch symptoms .

Another path, which I took, is to visit an allergist. I got tested for 46 different allergens, and all but onea slight allergy to dust mitescame back negative.

I decided to try OTC medications and rolled through a few, none of which had any effect on me whatsoever. After months of that, my allergist offered another diagnosis altogether: What I likely had was an almost-allergy. In some people, artificial fragrances create symptoms that mimic an allergic reaction, but theyre not actually allergies. I probably was hypersensitive to some manufactured scents and perfumes.

Can Allergies Go Away With Time

The short answer is yes.

Even if you develop allergies as an adult, you may notice they start to fade again when you reach your 50s and beyond.

This is because your immune function is reduced as you get older, so the immune response to allergens also becomes less severe.

Some allergies you have as a child may also go away when youre a teen and well into your adulthood, perhaps making only a few appearances throughout your life until they disappear permanently.

Why Are Childhood Food Allergies On The Rise

Childhood food allergies develop through a combination of genetic and environmental factors. The main risk factors are eczema, family history of food allergy, and delayed introduction of common allergy-causing foods .

While the first two main risk factors cannot be changed, we have control over when we feed a child common allergy-causing foods. This greatly influences the prevalence of childhood food allergies.

Starting approximately 20-30 years ago, doctors inadvertently gave advice that increased children’s food allergy risk. Back then, the advice was to avoid introducing common allergy-causing foods to a child for their first 1-3 years of life.

But thanks to recent landmark clinical studies , we now know that between 1997 and 2008, the amount of peanut allergies in children more than tripled, and that it is important to introduce allergens early.

In contrast, the results of these landmark studies show that introducing peanut, egg, and milk in a baby’s first year of life , and continuing to sustain exposure over several months, is important. Hopefully, the early introduction of foods like peanut, egg, and milk will become more commonplace.

How Can I Treat A Peanut Allergy

What causes peanut and nut allergies? How can you cure an allergy?

Carrying adrenaline and avoiding allergens are important steps, but small traces of peanuts can be found in many products. To build a tolerance to the point where you can actually eat peanuts without risk, you would need to follow a course of oral immunotherapy treatment .

OIT requires an individual to consume gradually increasing amounts of peanuts over a period of around 612 months. This process builds tolerance, reducing the chances your immune system will react to any peanut proteins in your body. With ongoing maintenance, you can substantially limit the risk of peanuts to yourself or to your child.

Emergency Treatment For Severe Allergic Reactions

If you are at risk of a severe allergic reaction , carry an adrenaline autoinjector such as EpiPenĀ® and a means of calling for medical assistance such as a mobile telephone. Emergency responses for a severe allergic reaction are:

  • lay the person flat do not allow them to stand or walk
  • administer adrenaline with an autoinjector
  • always dial triple zero to call an ambulance in a medical emergency.

If you are at risk of a severe allergic reaction, make sure you:

  • have a severe allergic reaction action plan
  • carry an adrenaline autoinjector to treat a severe allergic reaction
  • wear medical identification jewellery this increases the likelihood that adrenaline will be administered in an emergency
  • avoid medication that may increase the severity of allergic reaction or complicate its treatment such as beta blockers
  • seek medical advice.

If youre concerned that you have developed a new allergy, its best to check in with your primary doctor or allergist for testing and treatment. While occurrences rare, food allergies can cause difficulty breathing and require emergency treatment.

What Causes An Allergy

Allergies occur when your immune system attacks something that it sees as an invader but thats actually perfectly harmless, such as pollen, pet hair, or a particular food substance. That immune response can be mild, like sneezing or a runny nose, or it could be more severe, like breaking out in hives or the airways closing up and making it impossible to breathe.

Peanut allergies are actually the leading cause of near-fatal and fatal allergic reactions, otherwise known as anaphylaxis. This is why researchers are singling them out to see how they develop in people at various stages of life.

What Happens With A Tree Nut Or Peanut Allergy

Your immune system normally fights infections. But when someone has a nut allergy, it overreacts to proteins in the nut. If the person eats something that contains the nut, the body thinks these proteins are harmful invaders and responds by working very hard to fight off the invader. This causes an allergic reaction.

Common Food Allergies In Children

Overall, food allergies are more common in children than in adults.

The most common food allergies in children include milk, peanut, egg, and tree nut allergies.

Milk, egg, and peanut allergies are the most common food allergies in young children by far. According to one study by Dr. Ruchi Gupta, these three foods account for around 80% of food allergies in children age 5 and under.

In addition to milk, egg, and peanut allergies, tree nut allergies are also very common in children age 14 and under.

While many children tend to outgrow milk and egg allergies later in life, peanut and tree nut allergies are more likely to be lifelong.

According to the study, shellfish allergies are also among the top 5 food allergies in children age 14 and under. However, other studies have shown that shellfish allergies are much more common in adults than babies and young children. In addition, severe reactions to shellfish in children are rare.
