What Is Appendicitis?

Your appendix is a small, finger-shaped branch off your large intestine, in the lower right part of your belly, also called your abdomen . The appendix (say: uh- pen -diks) really has no purpose. So if a kid needs to have it removed, his or her body will work just fine after the operation. Some researchers think that many, many years ago, the appendix was once a useful part of the digestive system, but we don't use it any more.

When your appendix gets inflamed, or swells up, it's called appendicitis (say: uh-pen-duh- sye -tus). Both kids and adults can get appendicitis. There isn't always an obvious reason why appendicitis happens. Sometimes it happens after there is an infection in the intestine. Sometimes something causes a blockage in the appendix, such as food that was in the process of being digested. This blockage can cause appendicitis.

Appendicitis is not contagious. This means you can't catch it from anyone who has it. But there isn't much you can do to prevent appendicitis from happening.

How Do People Know if They Have It?
People have different types of symptoms when they have appendicitis. A person with appendicitis might feel as if he or she is having stomach cramps or really bad indigestion.

Usually, the first symptom is a bellyache around the belly button. Sometimes, vomiting follows. After a few hours, the pains tend to move down to the lower right side of the belly. Sometimes the pain can become sharp and intense in this area - enough to keep a kid up at night.

A person with appendicitis will not feel very hungry, and he or she might be constipated or have a slight fever . Some people do not want to move around because they feel better if they lie down and curl up.

What Do Doctors Do?
Any time you have belly pain, you should tell your mom, dad, or the adult who's caring for you. If your doctor thinks you could have appendicitis, you would need to go in for an office visit or go to the emergency department. At either place, a doctor will examine you, paying close attention to your belly.

The doctor can check for tenderness over your abdomen, especially over the lower right side of your belly, a spot known as McBurney's point . This spot hurts if a kid has appendicitis. The doctor also may test a small sample of the blood to see if there are a high number of white blood cells, which means there could be an infection in the body. Sometimes, doctors will take a special picture like an X-ray or CAT scan of the abdomen, too.

If the doctor decides that a kid has appendicitis, the appendix will need to be removed in an operation . To prepare for an appendectomy (the name for surgery that removes the appendix), a kid will be given anesthesia . This puts him or her into a kind of deep sleep and keeps the kid from feeling pain during the surgery.

During the operation, a surgeon will make a small cut in the abdomen and remove the appendix. The operation will leave a tiny scar.

After the Appendix Is Gone
After an appendectomy, a kid will stay in the hospital for a few days. The time that kids need to recover from this operation varies, but they usually return to school in about 1 to 3 weeks.

A person who's had an appendectomy will feel better soon, and he or she won't feel any different without an appendix. And here's some more good news: The kid won't ever have to worry about appendicitis again!
