Can You Develop An Egg Allergy

Sometimes It Remains The Same

Food Allergy 101: Manage Egg Allergy | Egg Allergy Symptoms

Pregnancy tends to change a lot about women, and it can even impact the physical reactions their bodies have to certain things. But that is not always the case. According to, there are times when women might not see any changes to their allergies at all when they are carrying a baby. Some women have had their symptoms to foods that they are allergic to remain the same while pregnant. This is something ladies should know if they have food allergies.

Symptoms Of Egg Allergy

Everyones immune system is different and egg allergy can cause diverse signs and symptoms, ranging from mild to severe. Symptoms can appear within a few minutes or a few hours of eating eggs or products containing eggs. 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 from enzyme deficiencies. Although these are not allergic reactions, they are often mistaken for allergies.If you or a child in your care have experienced any of these symptoms after eating egg, the risk of having another severe reaction after eating egg is greater than usual. Ask your doctor to refer you to a medical specialist .

What Adult Reactions Look Like

When it comes to types of food allergies, Guptaâs study finds shellfish is the top food allergen in adults, affecting 7.2 million of them.

âShellfish allergy commonly begins in adulthood, is rarely outgrown, and therefore impacts the lifespan,” she explains.

Jodi Duke has experienced that. She got an allergy to shellfish in her 30s after having her second child. Until then, she ate crab often and loved it. But during her last visit to a crab house, she took a bite and suddenly realized something had changed.

âI began to feel hot and dizzy. The next thing I remember was waking up on the floor. I had passed out and ended up in an ambulance headed to the emergency room. After several tests, the doctors explained that everything looked good on the tests and I should consult an allergy specialist,â Duke explains. âWhen I did, I found out I had developed a shellfish allergy and am now unable to eat any type of shellfish. I am lucky that my allergy is the type that I have to actually eat the shellfish to have a reaction, but I do still have to be careful.â

Guptaâs study found rates of all allergies, no matter when they started, were high in adults for a variety of other foods too, including:

  • Milk
  • Tree nut
  • Fin fish
  • Egg

Exercise As A Contributing Factor

There is a condition called food-dependent, exercise-induced anaphylaxis . Exercise can trigger hives and more severe symptoms of an allergic reaction. For some people with this condition, exercise alone is not sufficient, nor consumption of a food to which they are mildly allergic sufficient, but when the food in question is consumed within a few hours before high intensity exercise, the result can be anaphylaxis. Egg are specifically mentioned as a causative food. One theory is that exercise is stimulating the release of mediators such as histamine from IgE-activated mast cells. Two of the reviews postulate that exercise is not essential for the development of symptoms, but rather that it is one of several augmentation factors, citing evidence that the culprit food in combination with alcohol or aspirin will result in a respiratory anaphylactic reaction.

How Can Doctors Tell Its An Egg Allergy

Food allergies: Symptoms, treatments, and causes

If your doctor thinks you might have an egg allergy, he or she will probably refer you to an allergist or allergy specialist for testing. The allergy specialist will ask you questions these may cover things like how often you have the reaction, the time it takes between eating a particular food and the start of the symptoms, and whether any family members have allergies or conditions like eczema and asthma.

The allergy specialist may do a skin test on you. This test involves placing liquid extracts of egg protein on a persons forearm or back, pricking the skin a tiny bit, and waiting to see if a reddish, raised spot forms. If it does, its a sign the person is having an allergic reaction.

You will need to stop taking certain medicines 5 to 7 days before a skin test. Medicines like antihistamines and cold medicines can mess up allergy test results. Ask the staff at the allergists office which medicines you should stop taking and for how long.

Some doctors also may take a blood sample and send it to a lab, where it will be mixed with some of the suspected allergen and checked for an allergy-causing antibody called immunoglobulin E .

In some cases, positive results of skin and blood tests arent enough to prove that a persons symptoms are definitely caused by eggs. So doctors may use whats called a food challenge to help diagnose the allergy.

Living With An Egg Allergy

The best way to be sure a food is egg free is to read the label. Manufacturers of foods sold in the United States must list on their labels whether a food contains any of the most common allergens. This means that you should be able to find statements like these somewhere on the label: contains egg ingredients,made using egg ingredients, or made in a facility that also processes eggs.

Still, to make sure the foods you eat are egg free, it helps to look at the label for any ingredients that might come from eggs. That also means asking questions when eating out at restaurants or at a friends home.

The word egg is easy to spot on an ingredients list anytime you see words like egg solids or dried egg, youll know to avoid that food. But sometimes food labels arent so clear. Heres how eggs might show up on an ingredients list:

  • albumin
  • Simplesse
  • vitellin

When you eat in a restaurant or at a friends house, try to find out how foods are cooked and whats in them. In some cases, you may want to bring your own food with you. When youre shopping, look for egg-free alternatives to foods like pasta that usually contain eggs.

People with an egg allergy may find that the health food section of the grocery store offers the most options. Thats where youll find vegan foods that are made without eggs or egg products.

When preparing your own food, you can substitute one of these egg alternatives in your recipes. Each of these replaces one egg :

Dining Out At Restaurants

The biggest gray area in avoiding eggs is dining out at a restaurant. You can still enjoy this experience, but be prepared to do your research and ask a lot of questions. Since you cant see the ingredients of the items on the menu, if you suspect any food might have eggs, make sure you ask about it. Even a salad, which may seem like a relatively foolproof dining option, can be covered in a dressing that uses egg.

Given how common egg allergies are, most restaurants will want to accommodate you, offering suggestions of what you can safely eat.

What Should I Do If I Think My Child May Have An Egg Allergy

You should ask your GP for advice and a proper diagnosis. Eggs may be present in cakes, custard, mayonnaise and some pasta, as well as in some breads, in the glazes on buns or pies, and in some confectionery, so if all egg-containing foods are to be avoided by your child, you will need the help of a registered dietitian. It is advisable to keep a record of any occasions when an egg-containing food is eaten by mistake and of any symptoms that may follow, so that a judgment can be made as to whether the symptoms are diminishing.

What Is An Egg Allergy And What Are Its Symptoms

An allergy to eggs generally means your body produces an immune response when it encounters egg proteins. As a result, a person can be allergic to either the whole egg, just the whites, or just the yolk . According to Lee, when we think of an egg allergy, we usually think of eggs causing what she calls an immediate life-threatening reaction. That means you see the reaction typically within 30 minutes of ingesting the egg, though symptoms might improve after a few hours.

Causes Of Egg Allergy

For all allergies, the immune system reacts to specific allergy trigger molecules . Your immune system, or that of a child in your care, produces antibodies that detect the allergen and cause inflammatory reactions and the release of a chemical called histamine. Histamine causes hives, hay fever and other allergic symptoms.The molecules that trigger your allergic reaction can be either in egg whites or egg yolks, but allergies to egg whites are more common. The specific molecule in eggs that triggers your allergy may be present in both chicken eggs and duck eggs. Some people can therefore be allergic to both chicken and duck eggs. This is known as cross-reactivity. Speak to your doctor about cross-reactivity because it is difficult to predict.

What Happens With An Egg Allergy

Eggs arent bad. But when youre allergic to them, your body thinks they are. The bodys immune system normally fights infection. But when someone is allergic to a food, like eggs, the immune system overreacts to proteins in that food.

Most people who are allergic to eggs react to the proteins in egg whites, but some cant tolerate proteins in the yolk. Every time the person eats an egg, the body thinks these proteins are harmful invaders. The immune system responds by kicking into high gear to fend off the invader. This causes an allergic reaction, and chemicals like histamine are released in the body.

The release of these chemicals can cause someone to have the following problems:

  • wheezing
  • swelling
  • a drop in blood pressure

Egg allergies can cause a severe reaction called anaphylaxis. Anaphylaxis may begin with some of the same symptoms as a less severe reaction, but then quickly worsen. A person might have trouble breathing, feel lightheaded, or pass out. If its not treated, anaphylaxis can be life threatening.

Egg allergy usually first shows up when kids are very young. Most kids outgrow an egg allergy by the time theyre 5 years old, but some people stay allergic.
