Inflammatory bowel disease refers to two chronic (or recurring) conditions called “Crohn’s disease” and “ulcerative colitis,” which cause redness and swelling (inflammation) in parts of the intestinal tract. Like asthma, IBD symptoms in children occur in bouts — periodically flaring up for sometimes weeks or months.
What’s the Difference Between IBS and IBD?
Often confused with irritable bowel syndrome (IBS), IBD is a condition that can cause the intestines to narrow and restrict food from moving through the bowel. IBS is a functional disorder, which means the digestive system looks perfectly normal, but it doesn’t work exactly like it should. IBD and IBS have many similar symptoms, but IBS doesn’t cause blood in the stool (bowel movements or poop) like IBD can.
Crohn’s vs. Ulcerative Colitis in Children
Crohn’s disease and ulcerative colitis are both inflammatory bowel diseases that cause inflammation to different parts of the digestive system. Crohn’s can occur anywhere along the intestinal tract, but it’s commonly found in the last segment of the small intestine (ileum) and the large intestine (colon). Ulcerative colitis mostly affects the colon.
Crohn’s impacts the entire thickness of the intestine and can affect more than one section of the intestinal tract. In contrast, ulcerative colitis occurs only within the inner lining of the organ and is found only in one spot.
What Causes IBD in Children?
The exact cause of IBD in children is unknown. However, experts agree that the environment, genetics, and/or diet may have something to do with it. Scientists believe that an overactive immune system may trigger inflammation in response to an offending agent, like a virus or certain foods. Researchers are actively studying IBD to get to the bottom of possible causes, and hopefully help relieve IBD symptoms in children and adults.
Helping your child manage an egg allergy means being aware of what he or she eats and reading food labels carefully. It's work, but it's important.
About Egg Allergy
Eggs in themselves aren't bad, but when someone is allergic to them, the body thinks they are. When a person is allergic to eggs, the body's immune system overreacts to proteins in the egg. So every time something made with eggs enters the digestive system, the body thinks that these proteins are harmful invaders.
The immune system responds by creating specific antibodies to that food, which are designed to fight off the "invader." These antibodies — called immunoglobulin E (IgE) — trigger the release of certain chemicals into the body, one of which is histamine.
So when a child with an egg allergy eats a food that contains eggs, the immune system unleashes an army of chemicals to protect the body. The release of these chemicals can affect the respiratory system, gastrointestinal tract, skin, and the cardiovascular system — causing allergy symptoms like wheezing, nausea, headache, stomachache, and itchy hives.
Most people who are allergic react to the proteins in egg whites, but some can't tolerate proteins in the yolk. Egg allergy usually first appears when a child is very young, and most kids outgrow it by the time they're 5 years old.
Egg allergy is like most food allergy reactions: It usually happens within minutes to hours after eating eggs. Most reactions last less than a day and may affect these three body systems:
the skin: in the form of red, bumpy rashes (hives), eczema, or redness and swelling around the mouth
the gastrointestinal tract: in the form of belly cramps, diarrhea, nausea, or vomiting
the respiratory tract: symptoms can range from a runny nose, itchy, watery eyes, and sneezing to the triggering of asthma with coughing and wheezing
Most kids with egg allergy have some of the reactions listed above, but a few may have a very strong reaction called anaphylaxis. This severe allergic reaction causes swelling of the mouth, throat, and airways leading to the lungs, resulting in breathing difficulty. In addition, there is a dangerous drop in blood pressure, which can make a child dizzy or pass out, and may quickly lead to shock.
If your doctor thinks your child might have an egg allergy, he or she will probably refer you to an allergist or allergy specialist for further testing. The allergy specialist will ask things like how often your child has the reaction, the time between eating the food and the start of symptoms, and whether any other family members have allergies or conditions like eczema and asthma.
The allergy specialist may do a skin test. This involves placing liquid extracts of egg protein on a child's forearm or back, pricking the skin a tiny bit, and waiting to see if a reddish, raised spot forms, indicating an allergic reaction.
Your child will need to stop taking anti-allergy medicines (such as over-the-counter antihistamines) 5 to 7 days before the skin test because they can affect the results. Most cold medicines and some antidepressants also may affect skin testing. Check with the allergist's office if you're unsure about what medicines need to be stopped and for how long.
The doctor also might take a blood sample and send it to a lab, where it will be mixed with some of the suspected allergen and checked for IgE antibodies.
In some cases, positive results of skin and blood tests aren't enough to prove that symptoms are being caused by eggs. So doctors may use what's called a food challenge to help diagnose the allergy. In a food challenge, the child will eat foods that contain eggs while being very closely watched by the doctor. If symptoms appear after eating egg products, it's likely the child has an egg allergy.
Treating egg allergy might seem simple — just make sure your child doesn't eat eggs. But so many foods are made with eggs and egg products that it can be really hard to know what's OK and not OK to eat. Consider working with a registered dietitian to develop an eating plan that has all the nutrients your child needs while avoiding things made with eggs.
If your child has a severe egg allergy — or any kind of serious allergy — your doctor may want you to carry a shot of epinephrine with you in case of an emergency. Epinephrine comes in an easy-to-carry container about the size of a large marker. It's easy to use — the doctor will show you how to give a shot to your child should you ever need to.
If your child accidentally eats something with egg in it and starts having serious allergic symptoms, like swelling inside the mouth, chest pain, or difficulty breathing, give the shot right away while you wait for medical help. Always call for emergency help (911) if your child has needed to use epinephrine. Besides keeping epinephrine in your home, briefcase, or purse, also be sure it's at relatives' and other caregivers' homes and at childcare or school.
Also carry an over-the-counter antihistamine as this can help ease allergy symptoms in some kids. Antihistamines should be used in addition to the epinephrine and not as a replacement for the shot.
If your child has had to have an epinephrine shot because of an allergic reaction, go immediately to a medical facility or hospital emergency room so they can provide additional treatment if needed. Up to one third of anaphylactic reactions can have a second wave of symptoms several hours following the initial attack. So your child might need to be watched in a clinic or hospital for 4 to 8 hours following the reaction.
Getting the Flu Vaccine
In the past, it was recommended that anyone with an egg allergy talk to a doctor about whether receiving the flu vaccine was safe because it is grown inside eggs. But health experts now say that the amount of egg allergen in the vaccine is so tiny that it (but not the nasal mist) is safe even for kids with a severe egg allergy. The flu vaccine is recommended for all kids older than 6 months of age during flu season.
A child with an egg allergy that affects the skin (with a rash, itchiness and/or swelling) should get the flu shot in a doctor's office, not at a supermarket, drugstore, or other venue. If the allergy is severe (causing anaphylaxis), the child should get the flu vaccine in an allergist's office.
The nasal mist is not recommended for people with an egg allergy because the risks are currently unknown. Doctors are studying its safety in people with egg allergies and until these studies are completed, it's safest to get the flu shot.
Food Labels: What to Avoid
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. So look for statements like these somewhere on the label: "contains egg ingredients," "made using egg ingredients," or "made in a facility that also processes eggs."
This label requirement makes things a little easier than reading the ingredients list — instead of needing to know that the ingredient "ovoglobulin" comes from egg protein, you should be able to tell at a glance which foods to avoid.
Still, to make sure the foods your child eats are egg free, you'll need to be on the lookout for any ingredients that might come from eggs. That means asking questions when eating out at restaurants or others' homes and carefully reading food labels.
Here's how eggs, in their many forms, are listed on food labels:
egg white solids
Also avoid these ingredients:
Living With an Egg Allergy
Try to find out how foods are cooked and what's in them. When you're out and about or visiting friends, you may want to bring your child's own food with you. When food shopping, look for egg-free alternatives to foods that usually contain eggs, such as pasta.
When preparing food, use one of these egg alternatives in recipes. Each of these replaces one egg (these substitutes may not work as well in recipes that call for more than three eggs):
1 packet gelatin + 2 tablespoons warm water (don't mix until ready to use)
1 tablespoon pureed fruit, such as apricots or bananas
When cooking at home, always carefully scrub the utensils you're using in case they have been used on egg products.
Although the number of people in the United States with food allergies is low (just over 1% of the total population), there's a growing awareness about food allergies. This means that everyone — from the waitstaff at a restaurant to food manufacturers — is more understanding and willing to accommodate a child's food needs.
