(HealthDay News) -- Appendicitis occurs when the appendix becomes inflamed. The condition sometimes requires surgery to remove the organ before it bursts.
Appendicitis typically starts with pain in the abdomen around the belly button, says the Nemours Foundation. The pain often is accompanied by a mild fever, vomiting, nausea, constipation or diarrhea. As the condition progresses, the pain may intensify and move from around the belly button to the lower right side of the abdomen.
Appendicitis should never be ignored, since there may be serious complications if there's an infection or if the organ bursts. If you suspect that your child may have appendicitis, contact his doctor immediately.
