Appendicitis is a condition in which your appendix gets inflamed. The appendix is a small pouch attached to the large intestine.
Appendicitis is a very common cause of 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.
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 include:
- Chills and shaking
- Hard stools
- Nausea and vomiting
Exams & Tests
Your health care provider may suspect appendicitis based on the symptoms you describe.
Your provider will do a physical exam.
If you have appendicitis, your pain will increase when your lower right belly area is pressed.
If your appendix has ruptured, touching the belly area may cause a lot of pain and lead you to tighten your muscles.
A rectal exam may find tenderness on the right side of your rectum.
A blood test will often show a high white blood cell count. Imaging tests that may help diagnose appendicitis include:
CT scan of the abdomen
Ultrasound of the abdomen
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 for other causes of your pain.
