Can Food Allergies Cause Asthma Attack

For Children With Allergies And Asthma In School

Do food allergies cause asthma attacks?

For asthma prevention at school when your child has allergies and childhood asthma:

  • Discuss their allergies and asthma with school personnel.
  • If your child has food allergies, discuss them with school officials, teachers, and lunchroom staff.
  • Educate your child about their allergies and asthma early, so your child can learn to avoid situations where they may eat food that will trigger an allergic reaction. Arrange for an epinephrine kit to be left at the school, and make sure school officials are able to use it correctly and without hesitation should symptoms arise.
  • Inform school personnel about the asthma treatments your child is taking, and make arrangements to leave necessary medication at school.
  • Encourage sports participation, but inform coaches of medicines that may need to be taken before activities to prevent exercise-induced asthma.

Can Food Allergies Trigger Asthma

It might not be common knowledge, but there is a link between asthma and food allergies. More than one-third of children with food allergies have asthma, and around eight percent of kids with asthma have food allergies. Food allergies are considered to be a hidden asthma trigger and can cause potentially life-threatening asthma attacks. If you develop food allergies early in life, you have greater chances of developing respiratory problems such as asthma later in life. Doctors aren’t sure why contact with food allergens causes asthma attacks, but it might have to do with inflammatory responses that food allergies trigger in the immune system.

Food allergies are a response by your body’s immune system to a food it thinks is harmful. Symptoms of food allergies include reactions of the skin, eyes, nose, mouth, cardiovascular, gastrointestinal and respiratory systems. An asthma flare-up is one possible respiratory response. An asthma attack occurs when something triggers a hypersensitivity of the airways. Contact with food allergens is one possible trigger.

Food Additives And Asthma

Food preservatives, food colorings, and flavoring agents have been found to cause asthma attacks in some people, so make sure to read food labels. Sodium bisulfite, potassium bisulfite, sodium metabisulfite, potassium metabisulfite, and sodium sulfite are all potential triggers. Sulfites are the most common, Zitt explains. “Some people have trouble with delicatessen meats that are high in nitrites, while others may experience asthma symptoms from monosodium glutamate or from yellow food coloring containing tartrazine. Still, he adds, the scientific evidence regarding some of these potential triggers remains in dispute.

What Is The Link Between Asthma And Food Allergy

It is clear that asthma and food allergies co-exist for many and having both worsens the prognosis. However, there are still unanswered questions regarding the relationship between these entities. It is possible that greater atopy in general is associated with more severe, persistent, and/or earlier-onset asthma and food sensitization, with no direct causal relationship between food ingestion and asthma exacerbations.

It should be noted that for a subset of patients, respiratory symptoms, including wheezing, are induced by foods up to 30% of the time for food allergic individuals and several reports have indicated that severe asthma is risk factor for fatal food anaphylaxis . Food-induced repiratory symptoms should be managed differently from asthma exacerbations triggered by other common triggers, with injectable epinephrine as the treatment of choice as opposed to inhaled beta-agonists. Thus, the evidence supporting a causal relationship between food allergies and asthma should not be ignored.

The Rise In Food Allergy Cases

The number of people with food allergies has risen sharply over the past few decades and,;although the reason is unclear, other allergic conditions such as atopic dermatitis have also increased.

One theory behind the rise is that a typical child’s diet has changed considerably over the last 30 to 40 years.

Another theory is that children are increasingly growing up in “germ-free” environments. This means their immune systems may not receive sufficient early exposure to the germs needed to develop properly. This is known as the hygiene hypothesis.

What You Can Do To Avoid Triggers

In addition to properly managing your asthma with medications, its important to know what your asthma triggers so that you can avoid them.

  • Speak with your doctor about having an allergy test done. Write down what you are allergic to and learn how to avoid or reduce your allergen exposure.
  • Use an Asthma Action Plan and an asthma diary or journal to keep track of your asthma symptoms and what triggered them. Review your findings with your healthcare provider to determine your asthma symptoms.

Once you have a clear idea of the things that make your asthma worse, take action and make plans to control your exposure to these triggers. Some triggers will be difficult to avoid , but many of them are avoidable. Start with your own home, and its indoor asthma triggers many of us spend a lot of time at home and its environment is under your immediate control.

Here are some tips for controlling your home environment:

Asthma And Food Allergies

People who have both food allergy and asthma may be at increased risk for severe allergic reactions. However, many people who do not have asthma can also suffer from anaphylactic food reactions.

All individuals with food allergies need to carry an epinephrine auto-injector at all times. Likewise, all individuals with asthma need to be prepared with their emergency asthma medications.

If you have asthma, you must take preventative steps and take your prescribed medications, including emergency medication as needed. Daily life requires a high level of awareness, planning, and educating others about your health condition. Teachers, co-workers, neighbours, and family can all help you live safely with asthma.

Asthma & Allergy Tip: Respiratory Allergies

For these individuals, the following tests may be used alongside IgE blood tests and food challenges:

  • Skin prick testing,;in which tiny amounts of food allergens are placed under the skin to see if a reaction occurs
  • Elimination diets, in which foods are temporarily removed from the diet and then gradually reintroduced one-by-one to see if an allergy occurs

There are other tests used by some practitioners that are not recommended by the AAP or the American Academy of Allergy, Asthma & Immunology . These include food IgG testing, applied kinesiology, provocation neutralization, hair analysis, and electrodermal testing. None of these have any scientific evidence to support their use in the diagnosis of a food allergy.

Always seek care from a board-certified allergist/immunologist if you are seeking the diagnosis or treatment of a severe allergy.

Food Allergies And Sensitivities

Food allergies

Although a lot of food allergies start in childhood, you can develop them as an adult too.

Some of the most common food allergens are gluten , shellfish, eggs, milk, tree nuts, peanuts, sesame seeds, and soya.

Some food allergies, such as allergies to milk and eggs, are more common in children.

People with food allergies need to be strict about avoiding certain foods. Allergic reactions to food can happen very quickly. A severe allergic reaction can be life-threatening.

Reactions to food can quickly bring on asthma symptoms too, like wheezing, coughing and breathing difficulties.

An anaphylactic reaction and an asthma attack can look similar. If you have both a food allergy and asthma, and are in any doubt about your symptoms, use your auto-injector pen and get help straight away.

You can also find out more about particular food allergies on;the NHS website.

Food sensitivities

Being sensitive to certain foods is not the same as a true allergy. Theres less clear-cut evidence to show a link to asthma symptoms. However, it could be that some of the chemicals and ingredients in food and drink products trigger asthma symptoms.

The most common food sensitivities that can trigger asthma symptoms are:;

What Should I Do If I Have Food Allergies And Asthma

There are simple ways to say safe:

  • Avoid the food trigger. Try not to come into contact with the food youâre allergic to. Always read labels and ask how foods are prepared when you eat out.
  • Consider allergy shots. They can train your immune system to not overreact. The doctors will give you allergy shots — a small amount of the substance that causes your allergy. After repeated shots over a period of time, your immune system eventually stops causing the allergic reaction. Ask your doctor if youâre a candidate for allergy shots. Sublingual immunotherapy is an alternative to allergy shots. You let the medicine dissolve under your tongue instead of getting a shot.
  • Keep epinephrine with you. If your allergies are severe, you should keep two epinephrine shot kits with you that are always easy to get to. If you have any sign of anaphylaxis, donât hesitate to use the epinephrine auto-injector, even if you arenât sure your symptoms are allergy-related. Using the auto-injector as a precaution wonât hurt you and might save you. Dial 911 after you give yourself the shot.

What Is An Allergy

An allergy is the immune system‘s reaction when exposed to what is otherwise a harmless substance, such as plant pollen, mold, or animal hair, skin, or saliva. The immune system acts as a body defense, yet for people with allergies, the immune system treats these things, called allergens, as if they are harmful, causing a disruption to normal body functions. Allergens are what trigger a series of reactions by the immune system during an allergic reaction.

Asthma And Food Allergy In Children: Is There A Connection Or Interaction

This review explores the relationship between food allergy and asthma. They can share the same risk factors, such as parental allergy, atopic eczema, and allergen sensitization, and they often coincide in the same child. Coexistence may negatively influence the severity of both conditions. However, it remains to be determined whether food allergy may directly affect asthma control. An early food sensitization in the first year of life can predict the onset of asthma. Furthermore, asthmatic symptoms could rarely be caused by ingestion or inhalation of the offending food. Asthma caused by food allergy is severe and may be associated with anaphylactic symptoms. Therefore, an accurate identification of the offending foods is necessary in order to avoid exposure. Patients should be instructed to treat asthmatic symptoms quickly and to use self-injectable epinephrine.

At this point, it isn’t quite clear which allergen plays a larger role, but science is teaching us something new each day. If you suspect you have allergies, you can help yourself by booking an appointment with an allergist to determine what you are susceptible to. Positive reactions typically appear within 20 minutes, so it won’t involve days of testing.

Prevention Of Asthma And Food Allergy

Besides early introduction of food allergens and optimal treatment of the skin barrier, there is not much evidence for preventive interventions for the development of food allergy and asthma. A diet rich in omega-3 fatty acids and house-dust mite avoidance were suggested, but in studies, there turned out to be no effect . A Cochrane analyses reported little evidence for dietary intake or fish oil in order to improve asthma control . In addition, a study with maternal supplementation of fish oil during pregnancy did not show an effect on the progression of IgE-mediated allergic disease from 1 to 6;years of age . Furthermore, very low evidence was found in a recent systematic review that studied the effect of vitamin D supplementation in pregnant women, breastfeeding women, and infants on developing atopic diseases .

Breastfeeding remains the best advice for young babies according to the World Health Organization guidelines, but it does not appear to have a protective effect on the development of food allergy and asthma . However, delaying introduction of food by exclusively breastfeeding can result in a higher risk for a food allergy .

Altering the microbiome has been shown to have an effect on allergic diseases like food allergy; however, results are contradictive in different studies and studies are difficult to compare because of unequal methods . Therefore, more studies are needed to analyze interventions of the microbiome on the prevention of food allergy and asthma.

Mold Allergy Risk Factors

Not everyone whos exposed to mold will develop a mold allergy. However, if you do have a mold allergy or develop one, there are a handful of risk factors that could increase your likelihood of experiencing symptoms.

Frequent or increased exposure to mold is one of the biggest risk factors. For example, if your home isnt properly ventilated, then youre inviting mold to grow. Mold prefers warm, humid environments, and kitchens and/or bathrooms with insufficient ventilation have both in spades. Always try to improve ventilation and dispel excess moisture with fans or dehumidifiers.

The same is true of other areas in your home if you maintain a very humid environment. To discourage mold, you should try to maintain humidity at;no more than 50 percent. This goes for the whole home, as mold can develop anywhere that gets warm or moist enough, from carpets to walls.

The last two risk factors to keep in mind is your job and your family history. If you work in industries like furniture repair, winemaking, greenhouses, carpentry, millwork, baking, logging, dairy, and/or farming, you may be exposed to moldy conditions more often than the average person. A family background of asthma and/or allergies also increases your chances of getting a mold allergy and experiencing symptoms.

What Are Common Allergens That Can Trigger Allergic Asthma

What triggers allergic asthma may vary from person to person. Some common culprits that trigger allergic asthma include:

  • Pollen from grass, trees and weeds
  • Pet dander
  • Dust mites
  • Mold

People with allergies often find that their body reacts differently to different substances. Some allergens may cause a rash or eye symptoms; others may cause asthma symptoms. That is why it is important to know your triggers and how your body responds.

Other Dietary Sources Of Sulfites

Another sulfite trap is the produce section of your local supermarket. Reacting to safety concerns voiced in 1984, the FDA forbade the use of sulfites on pre-bagged lettuce in salad bars and produce sections. One loophole remains: potatoes. Some prepackaged potatoes, raw or cooked, could contain sulfites. You may want to skip the French fries just in case, unless you make them yourself.

Sulfites also appear in many prepared foods, so be sure to read labels. These include fresh or frozen shrimp, bottled lime or lemon juices, and pickled foods, among others. Also, they are often used in over-the-counter and prescription medications. If you are very sensitive to sulfites, check the labels or contact the manufacturer. Your local compounding pharmacist can prepare additive-free prescription medications.

Atopic Dermatitis And The Development Of Food Allergy

Another important risk factor for the development of both food allergy and asthma is atopic dermatitis. Prevalence numbers vary in literature, but percentages of 81% are described of pediatric patients with atopic dermatitis that will develop a food allergy later in life. In addition, a systematic review of Tsakok et al. reported an increased risk of six times of food sensitization in patients with atopic dermatitis compared to healthy controls in population-based studies . They also showed that up to 53% of patients with atopic dermatitis were food sensitized and up to 15% had a challenge proven allergy . A recent study, the EAT study, which analyzed prevention of food allergy by early introduction of food showed that at 3;months of age, children with atopic dermatitis showed 8.5 times more sensitization to food with a skin prick test compared to babies without atopic dermatitis. This was especially the case for egg and peanut and with increasing severity of atopic dermatitis . Guillet and Guillet studied children with atopic dermatitis and found an increase in prevalence of food allergy with increased severity of eczema . In children with severe atopic dermatitis, 100% sensitization to food was found with a clinical relevance of increase of their atopic dermatitis for almost all patients after intake of food allergens .
