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 of us eat food with 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: VIL-eye).
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, the 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 eats a lot, he or she
still might lose weight and could 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% to 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? About 1 in every 133 people in the United States has celiac disease.
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 it when they're between 6 months and 2 years old, which is when
most kids get their first taste of gluten in foods.
For some people, the problems start slowly and the symptoms may be terrible one
week and not as bad the next. Because of this, some people aren't diagnosed with celiac
disease until they're older. The problem is chronic,
which means that although symptoms may come and go, people who have celiac disease
will always have it.
Someone with celiac disease may feel tired and could be irritable. Some also have
skin rashes and mouth sores. The problem is sometimes mistaken for other digestiveproblems called inflammatory
bowel disease (IBD) 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 They Have It?
Someone who has a lot of stomachaches,
diarrhea, weight loss, or any of other symptoms of celiac disease should talk
to a doctor. It may or may not be celiac disease, but a doctor can help sort this
out and will usually order a screening blood test.
If the screening tests show a person might have celiac disease, the next stop usually
is to see a gastroenterologist, a doctor who specializes in digestive problems. This
specialist may decide to take a sample of the small intestine to look at under the
microscope. This small sample is called a biopsy.
If a biopsy is done, the doctor will give some special medicine to help the person
stay 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 someone's diet to cut out gluten.
It is important not to start a gluten-free diet unless you are truly diagnosed with
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 the intestines and, if this happens, the diarrhea, belly pain,
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?
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. In fact, nearly all of the foods
we eat can be made gluten free.
Besides foods that contain gluten, you'll need to watch out for foods that may
have been contaminated with gluten. This is called "cross-contamination." It means
a food doesn't contain gluten as an ingredient but came into contact with gluten-containing
foods. This is most likely to happen at home in your own kitchen — for instance,
wheat bread crumbs in the toaster, the butter, or jar of peanut butter.
If you have celiac disease you will need your own toaster and you should also have
separate spreads and condiments to avoid cross-contamination. Some foods are contaminated
during processing, so your mom or dad can help you by finding certified gluten-free
foods. 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 make sure that
they are gluten-free:
packaged rice mixes
There's also a labeling act that requires the labeling of wheat-free products.
But a "wheat-free" food isn't necessarily a "gluten-free" one because wheat-free
products may have barley and rye (gluten-containing grains) in them.
A diagnosis of celiac disease does not mean giving up all your favorite foods.
It just means adapting them to be free of gluten. Many different gluten-free
products, baking mixes, and recipes are available. 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, too. 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 this
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.
