What causes appendicitis?

It’s not clear what brings on appendicitis. Something triggers an inflammation (irritation and swelling) or infection in your appendix. Causes could include:

• Abdominal injury or trauma.
• Blockage at the opening where the appendix connects to the intestines.
• Digestive tract infection.
• Inflammatory bowel disease.
• Growths inside the appendix.
