Learn About Appendicitis

What is the definition of Appendicitis?

Appendicitis is a condition in which your appendix gets inflamed. The appendix is a small pouch attached to the end of the large intestine.

What are the causes of Appendicitis?

Appendicitis is a very common reason for emergency surgery. The problem most often occurs when the appendix becomes blocked by feces, a foreign object, a tumor or a parasite in rare cases.

What are the symptoms of Appendicitis?

The symptoms of appendicitis can vary. It can be hard to detect appendicitis in young children, older people, and women of childbearing age.

The first symptom is often pain around the belly button or mid upper abdomen. Pain may be minor at first, but becomes more sharp and severe. You may also have a loss of appetite, nausea, vomiting, and a low-grade fever.

The pain tends to move into the right lower part of your belly. The pain tends to focus at a spot directly above the appendix called McBurney point. This most often occurs 12 to 24 hours after the illness starts.

Your pain may be worse when you walk, cough, or make sudden movements. Later symptoms may include:

  • Chills and shaking
  • Diarrhea
  • Fever
  • Hard stools
  • Nausea and vomiting

What are the current treatments for Appendicitis?

Most of the time, a surgeon will remove your appendix as soon as you are diagnosed.

If a CT scan shows that you have an abscess, you may be treated with antibiotics first. You will have your appendix removed after the infection and swelling have gone away.

The tests used to diagnose appendicitis are not perfect. As a result, the operation may show that your appendix is normal. In that case, the surgeon will remove your appendix and explore the rest of your abdomen to check for other causes of your pain.

What is the outlook (prognosis) for Appendicitis?

Most people recover quickly after surgery if the appendix is removed before it ruptures.

If your appendix ruptures before surgery, recovery may take longer. You are also more likely to develop problems, such as:

  • An abscess
  • Blockage of the intestine
  • Infection inside the abdomen (peritonitis)
  • Infection of the wound after surgery
When should I contact a medical professional for Appendicitis?

Contact your provider if you have pain in the lower-right portion of your belly, or other symptoms of appendicitis.
