What Is Arthritis?

Arthritis (say: arth-ry-tiss) is a disease that causes swelling, stiffness, and pain in a person's joints.Joints are where two bones meet, allowing our bodies to move the hips, knees, ankles, elbows, shoulders, knuckles, etc. Joints contain synovial fluid, which acts as a lubricant to help them move easily.Arthritis can keep joints from working properly.

But isn't arthritis something that only old people get?

Actually, kids can get a kind of arthritis called juvenile idiopathic arthritis or JIA (it's also called juvenile rheumatoid arthritis, or JRA). Juvenile means young, so this means that JIA is different from the arthritis that adults get. Kids can have many different types of arthritis, but JIA is the most common.

Many problems can cause pain and swelling of the joints, so a doctor will want to know how long these problems have been going on. To be considered JIA, the joints must have swelling and pain for at least 6 weeks.

No one really knows what causes JIA. Something in the environment, like a virus, may trigger the disease in kids that already have certain genes that make it more likely for them to get it. (Genes are like instructions to the body on how to work. Genes are passed on from parents to their children and they decide everything from the color of a person's eyes to whether that person has a tendency to get a particular disease. Genes are part of our DNA and are found in the body's cells.)

JIA is not contagious, so you can't catch it from someone else.

Arthritis is an autoimmune (say: aw-toe-i-myoon) disease. An autoimmune disease means a person's immune system makes a mistake and attacks the body's own tissues or organs. Normally, a kid's immune system sends out white blood cells to protect the body and fight outside invaders like bacteria and viruses that can make a kid sick. But with an autoimmune disease like JIA, the immune system makes a mistake and attacks healthy cells.

Instead of recognizing the healthy cells and saying, "Hi, nice to see you," the immune system thinks the healthy cells need to be destroyed and releases chemicals to fight the healthy cells. The chemicals released by the immune system cause the pain and swelling that can happen with arthritis.

Just because a joint hurts doesn't mean a kid has JIA. A joint might hurt for a lot of different reasons, which is why it's important to see a doctor to figure out what the problem is.

The doctor will ask a lot of questions: How long has the kid had joint problems? Does he or she feel stiff when getting up or after resting? Are the joints swollen? Was there an injury? Could another problem be causing arthritis, such as Lyme disease? Is there a family history of arthritis or other autoimmune diseases?

Getting these answers and doing a physical exam, blood tests, and X-rays will help the doctor figure out if it is JIA. If your doctor thinks you may have it, he or she may send you to see a doctor who specializes in the diagnosis and treatment of arthritis. This kind of doctor is called a rheumatologist (say: roo-muh-tol-oh-jist).

Some kids who have JIA might take medicine like ibuprofen to help control pain and inflammation. If the arthritis is more severe, they may need to take other medicines to help lower the pain and inflammation. Some of these medicines are pills, but others are shots.

It's important that kids with JIA keep their joints moving. Often a kid will see a physical therapist or occupational therapist. In addition to working with children to move their joints and strengthen their muscles, these therapists can help create special exercise programs for home or school that can help a kid stay active.

In addition to joint problems, JIA may cause uveitis (say: yoo-vee-eye-tus), an inflammation of the eye that can lead to problems with vision if it's not treated. All kids diagnosed with JIA should get their eyes checked by an ophthalmologist, a doctor who specializes in diagnosing and treating eye problems. If the eyes are affected, they may be treated with eye drops.

Besides taking medicines, akid can do a few things to help with the symptoms of JIA:

Kids with JIA can have a lot of stiffness when they first wake up in the morning. Once their joints warm up, they can usually move more easily. That's why you might notice that someone with JIA has trouble moving early in the day, but seems better later on.

It's important to find a good balance between activity (which helps kids stay flexible) and rest (which everyone needs). Swimming is a great exercise for someone with JIA. It stretches a lot of different muscles and tendons and helps keep a kid moving and flexible. It's important to stay active even when a kid isn't having symptoms.

Sometimes kids with JIA can go a long time, even months or years, without the disease bothering them. Then it comes back. This is called a flare-up or flare. Flare-ups just happen and can't be prevented. It can be frustrating if a flare-up happens on a day when the kid would like to be doing something fun, like attending a birthday party.

If you know someone with JIA, you may offer to carry books or give other help, if needed. It's also OK if the person doesn't want help.

The good news is that many kids with JIA will outgrow it. About half of kids with JIA may not need treatment as adults.

And even when the arthritis flares up, almost all kids with JIA can control it with medicine and other treatments, which means they can do most things that other kids can do.
