Celiac Disease

Have you ever eaten gluten? No, not glue - gluten! If you've ever eaten a piece of bread, a slice of pizza, or a bowl of cereal, chances are you have. Gluten (say: gloo-tin) is a protein found in wheat, rye, and barley - grains that are in many everyday foods.
Most people can eat food containing gluten with no trouble. But for some people, eating gluten can cause a reaction in their bodies. Someone who has this problem has celiac (say: see-lee-ak) disease.

After you eat food, it goes to your stomach, which is part of a group of organs that make up your digestive system. An important part of the digestive system is the small intestine, which is lined with villi (say: vih-lie). Villi are usually described as microscopic, finger-like projections. Weird, huh? Fingers in your intestines! But don't forget that they're microscopic, meaning they are extremely small - so small you can't see them without a microscope. The villi are important because they absorb nutrients into the body.

For someone with celiac disease, eating gluten - in a piece of bread, for instance - causes an immune system reaction. Your immune system ordinarily keeps you from getting sick, but in someone with celiac disease, the body starts damaging and destroying the villi. Without villi, a person's body can't absorb vitamins and nutrients from food. Without enough nutrients, a kid's body has a tough time staying healthy and growing properly. Even if the person is eating a lot, he or she might still lose weight and might develop anemia (say: uh-nee-me-uh) from not absorbing enough iron.

Why Do Kids Get Celiac Disease?

No one is sure why celiac disease happens, but it appears to run in families. You have a 5-10% chance of getting celiac disease if someone in your family has it. It's common in people from the northern European countries and the United States. How common? We think that about one in every 133 people has celiac disease in the United States. Obviously, many people who have celiac disease do not know it. If all these people were diagnosed, celiac disease would be more common than Type 1 diabetes. Fortunately, awareness is growing about the problem, and there are better ways of testing people for it.

Signs and Symptoms

Some common symptoms of celiac disease are diarrhea, decreased appetite, stomachache and bloating, poor growth, and weight loss. Many kids are diagnosed with the problem between 6 months and 2 years of age. It makes sense because, at this time, kids are getting their first taste of gluten in foods. For some people, the problems occur gradually and the symptoms may be terrible one week and not as bad the next. Because of this, some people aren't diagnosed with the celiac disease until they are older. The problem is chronic, which means that the symptoms may go away and come back over and over again.
A person with celiac disease may feel tired, and he or she could be irritable. Some people with the disease also have skin rashes and mouth sores. The problem is sometimes mistaken for other digestive problems called inflammatory bowel disease or lactose intolerance. And in some cases, a kid won't have any symptoms and then will all of a sudden start having problems during a time of stress, such as after an injury.

How Do People Know If They Have It?

Someone who has a lot of stomachaches, diarrhea, weight loss, or any of the other symptoms mentioned above should talk to the doctor. It may or may not be celiac disease, but a doctor can help sort this out. The doctor will usually order a screening blood test.
If the screening tests show a person might have celiac disease, the next stop is usually a gastroenterologist, a doctor who specializes in digestive problems. This specialist may decide to take a sample of the person's small intestine to look at under the microscope. This small sample is called a biopsy. If a biopsy is done, the doctor will give the person some special medicine to keep him or her comfortable during the procedure.

How Is It Treated?

Celiac disease is treated by not eating gluten. This can be difficult because gluten is in many foods, but a dietitian can help adjust a person's diet to cut out gluten. It is important not to start a gluten-free diet unless you are truly diagnosed with celiac disease. Following a gluten-free diet allows the small intestine to heal. But that doesn't mean the person can start eating gluten again. For someone with celiac disease, gluten will always irritate their intestines and, if this happens, the diarrhea, stomachaches, and other problems will return.
If you're diagnosed with celiac disease, it can be a challenge to learn which foods contain gluten. You may not be able to remember them all, but you can keep a list with you, and ask about menu items at restaurants before digging in. Before you know it, you'll be a pro at knowing which foods are safe and which are not. Here's a quick quiz:
Which of these foods contain gluten?
pizza
fried chicken
pasta

If you said all three, you're right! Pizza was the easiest choice because you know the crust is bread. But did you know that battered foods like fried chicken and even some French fries contain gluten? Pasta also contains gluten because it is made from wheat. Luckily, you can make or buy gluten-free pizza crust, make fried chicken with a gluten-free batter, and find gluten-free pasta and French fries. In fact, nearly all of the foods we eat can be made gluten-free.
In addition to foods that contain gluten, you'll need to watch out for foods that may have been contaminated with gluten. That means a food that doesn't contain gluten as an ingredient, but came into contact with gluten-containing foods. This is most likely to occur at home in your own kitchen. For instance, wheat bread crumbs in the toaster, the butter, or peanut butter.

If you have celiac disease you will need your own toaster and you should also have separate spreads and condiments to avoid this cross-contamination. Some foods are contaminated during processing, so your mom or dad can help you by finding foods that are certified as gluten-free. For instance, gluten-free oats are now available for people with celiac disease.
The best approach is to read labels, but here are a few foods to steer clear of until you can verify that they are gluten-free:
packaged rice mixes
lunch meats
sausages
instant cocoa
canned soups

A diagnosis of celiac disease does not mean giving up all your favorite foods. It just means adapting them to be gluten-free. There are many different gluten-free products, baking mixes and recipes available to help. A support group is a great resource for finding out which recipes and products are best.

A support group can help keep you up to date as well. For instance, a few years ago it was recommended that distilled vinegar be completely avoided on a gluten-free diet. Now we know that the gluten molecules do not appear in the distillate. Huh? What it means is that distilled vinegar is now an OK ingredient. That made a big change in the allowed foods someone with celiac disease could eat.

If you're part of a support group, you hear of these kinds of changes right away. A support group is also a great place to get to know other kids who have celiac disease and to learn that you're not alone.

Do Allergies Cause Asthma?

People who have certain kinds of allergies are more likely to have asthma. Do you have allergies that affect your nose and eyes, causing stuff like a runny nose or red, itchy eyes? If so, you're more likely to have asthma, too. Whatever causes the allergic reaction, such as pollen or dust, can also trigger asthma symptoms.

But not everyone who has this kind of allergy gets asthma, and not all asthma happens because of allergies. Huh? Allergies and asthma can be a little confusing, so let's find out more.
About 6 million kids in the United States have asthma. Of these, about three out of four have asthma symptoms that are triggered by an allergy to something (called an allergen). In these people, the symptoms of asthma like wheezing, coughing, or trouble breathing are often brought on by being around allergens.

Allergies have a lot to do with your immune (say: ih-myoon) system. Most of the time your immune system fights germs and bacteria to help you stay healthy. But in a kid with allergies, the immune system treats allergens (like pollen) as if they're invading the body, like a bad germ.
When the immune system reacts to an invading allergen, the body releases substances that cause allergy symptoms, such as a runny nose or red, itchy eyes. Other kids can get asthma symptoms, like coughing, wheezing, or a tight feeling in the chest.

If you have asthma, it is a good idea to find out whether allergies may be causing your asthma symptoms. To figure out what they're allergic to, sometimes kids will visit a special doctor called an allergist (say: ah-lur-jist).

If the allergist finds out that you are allergic to certain things, the best way to prevent allergic reactions (and to help stop asthma symptoms from bugging you) is to avoid being around the allergens. The doctor may also prescribe medicine for your allergies, if you can't completely avoid what's causing them.
