The appendix is a reservoir that can hold a lot of infection. When it gets too much or it gets infected itself then it will react like most body tissue. It will become inflamed, the body will increase its temperature to fight the infection, and the body will send a lot of white blood cells to the site to fight the infection. This causes pressure and creates a swelling. If there is too much infection then it can burst.
Have you ever cleaned out puss from an infected wound? The puss is a lot of white blood cells trying to fight the infection. Have you noticed how the wound can become inflamed and sensitive? That is what is happening in an infected appendix.

What Is Appendicitis?
Appendicitis is an inflammation of the appendix, a small tubular piece of tissue about the size of a finger that connects to the large intestine, usually at the lower right side of the abdomen. The inside of the appendix forms a pouch that opens into the large intestine. With appendicitis, the appendix becomes inflamed and infected by bacteria because the inside of the appendix gets blocked - by a foreign body (such as a seed in food) that was swallowed or because of swelling in the intestine from an infection.
If the infected appendix is not removed, it can eventually burst or rupture from the buildup of pressure. This may happen as soon as 48 to 72 hours after symptoms start. The infection from a ruptured appendix is very serious - it can form an abscess (a walled-off infection of pus) or spread throughout the abdomen.
What Are the Symptoms of Appendicitis?
The classic symptoms of appendicitis are abdominal pain and loss of appetite. Abdominal pain usually begins in the center of the abdomen, around the area of the navel. Later, the pain may move downward and to the right, to an area called McBurney's point, which roughly corresponds to the location of the appendix in the lower right portion of the abdomen.
After abdominal pain begins, a person with appendicitis may develop a slight fever, lose his or her appetite, feel nauseated, and vomit. The fact that abdominal pain begins before nausea and vomiting, rather than after, is one clue that the problem might be appendicitis rather than a gastrointestinal infection. Another clue is that the pain associated with appendicitis doesn't come and go; it continues to get steadily worse.
Of course, some of the symptoms of appendicitis can occur in a variety of illnesses. That's why it's important that you call your doctor to help make a diagnosis.
If appendicitis isn't treated promptly, the infected appendix may perforate (break open) and the infection may spread to other areas of the abdomen. In this case, the abdominal pain may involve the whole abdomen, and a person's fever can become very high.
Who Gets Appendicitis?
Appendicitis eventually occurs in 7% of the U.S. population. Young people between the ages of 10 to 30 are most often affected. You can't catch appendicitis from anyone, and you can't give it to anyone, either. Doctors and researchers have not found a way to prevent it. Although appendicitis is less common in countries where people eat a high-fiber diet, experts have not proven that a high-fiber diet definitely lessens the risk of getting appendicitis.
How Long Does Appendicitis Take to Develop? How Long Does It Last?
There is no specific incubation period (the time it takes for symptoms to develop) for appendicitis. Once the appendicitis symptoms appear, it can take as little as 48 to 72 hours for the infected appendix to rupture. If the appendix ruptures, the infection will likely spread to other areas of the abdomen, increasing the risk of serious complications and making treatment more difficult.
If a person's infected appendix hasn't ruptured, a surgeon will usually operate to remove it. The operation generally has few complications, with a hospital stay of 1 to 3 days. After a few days of rest at home, a student can safely return to school. However, if the infected appendix ruptures before surgery, the person usually stays in the hospital longer to receive intravenous antibiotics that will help kill bacteria that may have spread to the abdominal cavity.
When Should I Call My Doctor?
Appendicitis is an emergency that must be treated surgically. It can't be treated at home. If you suspect that you have appendicitis, call a doctor immediately. This will give the doctor more time to confirm the diagnosis and to make sure that the infected appendix is removed before it can rupture.
To help make a diagnosis, your doctor will do a physical examination. In addition to the physical examination, the doctor will ask you about any concerns and symptoms you have, your past health, your family's health, any medications you're taking, any allergies you may have, and other issues. (This is called the medical history.) The doctor will usually do some tests - such as a blood count and urine examination - and may recommend an ultrasound examination of the appendix or X-rays of your abdomen and chest. The doctor will decide whether you need surgery.
Because your doctor will need to examine your abdomen for signs of pain and tenderness, ask before taking medications (such as acetaminophen or ibuprofen) to dull the pain. Don't take laxatives or use enemas until your doctor sees you because these can cause the appendix to rupture. Also, if your doctor suspects that you have appendicitis, you will probably be asked to stop eating or drinking (an important precaution when a person is possibly going to have surgery).
How Is Appendicitis Treated?
Appendicitis is treated with surgery to remove the infected appendix. Before and after surgery, you will receive intravenous (IV) fluids and medications. Even if the appendix has not ruptured, your doctor may prescribe antibiotics because they can decrease the risk of infection after surgery. Doctors usually remove a person's appendix through an incision (cut) in the abdomen that is about 1 1/2 inches (3.8 centimeters) long. But if a person's appendix has ruptured, surgery becomes more complex. The risk for complications also increases, and a longer hospital stay and treatment period will be necessary.
What Can I Do to Help Myself Feel Better?
The best thing you can do is to get help from your doctor right away if you suspect that you have appendicitis. Prompt treatment of appendicitis usually prevents complications and gets you back to your regular routine faster.
