A burst (ruptured) appendix typically causes severe symptoms requiring immediate medical attention. Key signs include: sudden, sharp abdominal pain that may start around the belly button and then spreads to involve the entire abdomen; high fever with chills; nausea and vomiting; swelling and bloating of the abdomen; inability to pass gas or have bowel movements; and a tender, rigid abdomen to the touch. Sometimes the pain may briefly ease but then return stronger. Other serious signs include rapid heartbeat, weakness, mental confusion, and feeling very ill. A burst appendix can lead to dangerous infections like peritonitis and sepsis, so emergency care is essential if a rupture is suspected.

Symptoms to watch for if appendix may have burst:

• Sudden, severe abdominal pain spreading beyond lower right abdomen
• High fever and chills
• Nausea, vomiting, and loss of appetite
• Abdominal swelling or bloating
• Inability to pass gas or stool
• Tender, rigid abdomen
• Rapid heartbeat, weakness, or confusion

If these symptoms appear, urgent medical evaluation is critical to prevent life-threatening complications.
