Risk Factors Of Food Allergies

Can you develop allergies later in life?

Risk factors can vary from patient to patient and allergy to allergy. Generally, those with a history of food allergies in the family are at a higher risk of developing a food allergy. Existing food allergies may also put one at a higher risk of developing a second food allergy.

Finally, patients with an environmental allergy such as an allergy to ragweed are at a higher risk of developing a food allergy if that food contains a protein similar to the one in the environmental trigger.

Symptoms Of Nut Allergies

Each persons immune system is different and peanut, tree nut and seed allergies can cause diverse signs and symptoms, ranging from mild to severe. Many food allergies do not cause severe symptoms, but they can be life threatening in some people and should be taken seriously.Some people have negative or adverse reactions to food that are not caused by allergies. These can be caused by factors such as food poisoning, toxic reactions or food sensitivities . Although these are not allergic reactions, they are often mistaken for allergies. Mild allergic symptoms that can occur before a severe allergic reaction include:

  • raised red bumps of skin hives
  • swelling of the lips
  • tingling of the throat and mouth
  • itchy skin and rash
  • tightening of the throat
  • digestive symptoms cramps, stomach pain, nausea or vomiting.

If you or a child in your care have experienced any of these symptoms after eating peanuts, tree nuts or seeds, the risk of having a severe reaction after eating that food is greater than usual. Ask your doctor to refer you to a clinical immunology or allergy specialist.

Why Are Food Allergies Increasing

The Centers for Disease Control and Prevention have reported a 50 percent increase in the number of children with food allergies since the late 1990s. Many theories have been suggested as to why the number of people with food allergies is growing, but scientific research has not yet found the cause.

An allergic reaction to food can have many different symptoms, and a single person can experience different symptoms from one reaction to the next. Many reactions start with skin symptoms, like hives or a rash, but some do not. More serious symptoms like a drop in blood pressure and trouble breathing can be life-threatening. Talk to your allergist and work with them to fill out a Food Allergy & Anaphylaxis Emergency Care Plan to be prepared in an emergency.

Factors That Can Tell If You Can Get A Peanut Allergy Later In Life

Though there are no fixed rules that can tell whether you can develop peanut allergy later in life or not, there are still some factors that can contribute in the likelihood. These are

  • If you have asthma
  • If you have other allergies
  • If any of your other family members have this allergy or any other allergy.

If the answer to all these questions is yes, you have chances of developing an atopy or sensitivity to certain things that are usually not harmful.

Can You Suddenly Become Allergic To Peanuts

Food allergies are much more complex than some people imagine and theres a lot we dont fully understand, including exactly why some people develop food allergies and others do not. While food allergies are most often diagnosed in childhood, they can be diagnosed anytime throughout the lifecycle. In addition, food allergies may be more transient than we first believed, as research shows that some people who have become tolerant of an allergy through immunotherapy lose protection when they stop immunotherapy. In addition, significantly more adults than children report convincing food allergies. Lets take a look at the what the research tells us about food allergy prevalence and some important considerations.

How many people have food allergies?

Do food allergies develop more often in childhood or adulthood?

According to an earlier study of 1,111 medical charts of food allergic adults from an allergy clinic, approximately 15% of these allergic adults had developed their food allergy during adulthood. The most common time frame for food allergy development in this population was in their 30s. The five most common food allergies in this adult population were shellfish , tree nut , fin fish , soy , and peanut . Like the previous study mentioned, these patients did not undergo oral food challenges, which is a significant limitation to the study. In addition, the data was collected from just one clinic.

Unproven Methods To Test For Allergies

A number of methods claim to test for allergies but have not been medically or scientifically proven. They can be costly and could lead to dangerous avoidance of certain foods. The Australasian Society of Clinical Immunology and Allergy , the organisation representing allergists in Australia, recommends that you do not use certain methods to have potential allergies tested. These methods include:

  • cytotoxic food testing
  • reflexology
  • Vega testing.

Always speak with your doctor if you are thinking of using a complementary medicine or therapy to test for allergies.

Food Allergy Symptoms In Adults

Feeding children peanuts may avoid allergies in later life

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.

What Is The Difference Between Food Allergy And Food Intolerance

Food allergy is sometimes confused with food intolerance. Food allergies involve your immune system and can be life-threatening. An intolerance is when your body has trouble digesting a food. It can make you feel bad, usually with an upset stomach, but it is not life-threatening. The most common intolerance is to lactosewhich is a natural sugar found in milk.

Types Of Food Allergies

Food allergies are divided into 3 types, depending on symptoms and when they occur.

  • IgE-mediated food allergy the most common type, triggered by the immune system producing an antibody called immunoglobulin E . Symptoms occur a few seconds or minutes after eating. There’s a greater risk of anaphylaxis with this type of allergy.
  • non-IgE-mediated food allergy these allergic reactions aren’t caused by immunoglobulin E, but by other cells in the immune system. This type of allergy is often difficult to diagnose as symptoms take much longer to develop .
  • mixed IgE and non-IgE-mediated food allergies some people may experience symptoms from both types.

Living With A Food Allergy

Can You Get a Peanut Allergy Later in Life?

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.

Developing An Adult Food Allergy Is A Life

Developing a food allergy in adulthood is a life-changer. Your carefree diet is out the window, and now you have auto-injectors, anaphylaxis risks, and lots of explaining. Meet those whove joined this brave new world.

ONE spring morning back in 2011, Sandy Williams was calmly sitting at her desk in her Washington, D.C. office, munching on one of her favorite snacks mixed nuts. As she ate, a strange sensation came over her, which rapidly progressed into the symptoms of a frightening anaphylactic reaction.

My eyelids started swelling and then my throat started closing, she recalls. Williams was taken to the hospital, and was soon in such poor condition that she had to be rushed into surgery to have a breathing tube inserted. From Monday through Thursday I was in a coma, with a breathing tube and all, she says.

After recovering, Williams was tested by an allergist and diagnosed with allergies to both tree nuts and soy. She was shocked: she was 52 at the time and had never had any allergy, food or otherwise. But here she was, not just allergic but reacting at the extreme end of the spectrum.

The fact that tree nuts were a culprit was especially peculiar, since they had always been a favorite. Ever since I could chew, three to four times a week I would eat nuts, she says.

Tracking the Clues

But she still had no real clue as to the culprit until she suffered an unnerving reaction at a restaurant.

Whats The Difference Between A Food Allergy And A Sensitivity

Many people think that lactose intolerance and a milk allergy are the same, but these are actually two distinct conditions. Lactose intolerance is a food sensitivity, while a milk allergy is a type of allergy. Food allergies and sensitivities involve different systems and responses in your body. They also have distinct sets of symptoms and pose different health risks.

Food And Pollen: A Mistaken Identity

Seasonal Allergies: Fact or Fiction with Dr. Jeff Millstein

Some adult-onset food allergies arise from preexisting allergies to pollen, one of the most common environmental allergens. With the body already on high alert for pollen and anything resembling it, an overzealous immune system can become even more hypervigilant and mistake proteins in fruits and vegetables for pollen. This can cause a mild to moderate allergic reaction, which doctors refer to as oral allergy syndrome. It most commonly occurs as a misidentification of birch tree pollen, manifesting itself in allergic reactions to fresh fruits. Frustratingly, this allergy may not reveal itself until later in life.

When To Seek Medical Advice

If you think you or your child may have a food allergy, it’s very important to ask for a professional diagnosis from your GP. They can then refer you to an allergy clinic if appropriate.

Many parents mistakenly assume their child has a food allergy when their symptoms are actually caused by a completely different condition.

Commercial allergy testing kits are available, but using them isn’t recommended. Many kits are based on unsound scientific principles. Even if they are reliable, you should have the results looked at by a health professional.

Food Sensitivities And Intolerances Begin In Your Digestive System

Sometimes, your digestive system cant properly break down certain kinds of foods. When you ingest these foods, you may experience bloating, diarrhea, constipation, stomach pain, and gas. This type of reaction is called a food intolerance or sensitivity.

Unlike a food allergy, food sensitivities are rarely life-threatening, although they can cause plenty of pain and discomfort. You may be able to manage your food intolerance symptoms using over-the-counter enzyme replacements.

Can You Develop Seasonal Allergies Later In Life

A food allergy develops when the immune system mistakenly labels the food as a threat and launches an attack against it, Harvard Health experts say.

For people with peanut allergies, even a small amount of peanuts can cause a serious, possibly life-threatening reaction. Symptoms usually start minutes after exposure, according to the Mayo Clinic.

The most common symptoms include skin reactions such as hives or redness, an itching or tingling in the mouth or throat, nausea or vomiting, tightening of the throat and wheezing.

Any severe reaction requires treatment with an epinephrine autoinjector and an emergency department visit. Anaphylaxis symptoms include trouble breathing, a sharp drop in blood pressure, a rapid pulse, dizziness and loss of consciousness.

Peanut allergies are a leading cause of fatal and near-fatal anaphylaxis. People who suspect they may have peanut allergies should get evaluated by their physicians as soon as possible.

The U.S. Food and Drug Administration has not approved any therapies for adults with peanut allergies, An oral immunotherapy has been approved for patients 4 to 17 years of age to help desensitize them to peanuts.

What Causes Food Allergies

Food allergies happen when the immune system the body’s defence against infection mistakenly treats proteins found in food as a threat.

As a result, a number of chemicals are released. It’s these chemicals that cause the symptoms of an allergic reaction.

Almost any food can cause an allergic reaction, but there are certain foods that are responsible for most food allergies.

Foods that most commonly cause an allergic reaction are:

  • milk
  • shellfish
  • some fruit and vegetables

Most children that have a food allergy will have experienced eczema during infancy. The worse the child’s eczema and the earlier it started, the more likely they are to have a food allergy.

It’s still unknown why people develop allergies to food, although they often have other allergic conditions, such as asthma, hay fever and eczema.

How To Get Tested

A food allergy will usually cause some sort of reaction every time the trigger food is eaten. Symptoms can vary from person to person, and you may not always experience the same symptoms during every reaction. Allergic reactions to food can affect the skin, respiratory tract, gastrointestinal tract and cardiovascular system. It is impossible to predict how severe the next reaction might be, and all patients with food allergies should be carefully counseled about the risk of anaphylaxis, a potentially fatal reaction that is treated with epinephrine .

While food allergies may develop at any age, most appear in early childhood. If you suspect a food allergy, see an allergist, who will take your family and medical history, decide which tests to perform and use this information to determine if a food allergy exists.

To make a diagnosis, allergists ask detailed questions about your medical history and your symptoms. Be prepared to answer questions about:

  • What and how much you ate
  • How long it took for symptoms to develop
  • What symptoms you experienced and how long they lasted.

After taking your history, your allergist may order skin tests and/or blood tests, which indicate whether food-specific immunoglobulin E antibodies are present in your body:

Your allergist will use the results of these tests in making a diagnosis. A positive result does not necessarily indicate that there is an allergy, though a negative result is useful in ruling one out.
