Appendicitis is an inflammation of the appendix, a pouch-shaped organ connected to the large intestine. If you don’t get treatment for it, the appendix can rupture, which is a life-threatening situation.
Low-grade fever and chills
Appendicitis usually causes a fever between 99°F (37.2°C) and 100.5°F (38°C). You may also have the chills. If your appendix bursts, the resulting infection could cause your fever to rise. A fever greater than 101°F (38.3°) and an elevation in heart rate may indicate that the appendix has ruptured.
Vomiting, nausea or loss of appetite
Appendicitis can cause nausea and vomiting. You may lose your appetite and feel like you can’t eat. You may also become constipated or develop severe diarrhea. If you’re having trouble passing gas, this may be an indication of a partial or total obstruction of your bowel. This may be related to underlying appendicitis.
The site of your pain may vary, depending on your age and the position of your appendix. When you're pregnant, the pain may seem to come from your upper abdomen because your appendix is higher during pregnancy.
When to see a doctor
Make an appointment with a doctor if you or your child has worrisome signs or symptoms. Severe abdominal pain requires immediate medical attention.
