Your appendix is a tube-shaped sac attached to your large intestine. Experts disagree on the exact purpose of the appendix, but agree that as we age, our body no longer needs it. Sometimes, a blockage in the lining of the appendix can lead to infection (appendicitis) and cause the appendix to burst—a life-threatening condition. Because your appendix can rupture as soon as 48 to 72 hours after symptoms start, you should seek out emergency care if you experience the following symptoms:
Sudden pain or aching around your belly button or right hip bone that worsens when you walk or move quickly
Nausea and vomiting
Loss of appetite
Low-grade fever that increases as illness progresses
Bloating and change in bowel movements (constipation or diarrhea)
