Peritonitis is a serious condition. It requires immediate treatment. If not promptly treated, it can be fatal.
Primary peritonitis—Occurs when there is a buildup of fluid in the abdomen. This is called

- Secondary peritonitis—Caused by bacteria that enter the abdominal cavity. Can be due to an injury or a condition, such as a ruptured appendix.
Dialysis-related peritonitis—Caused by bacteria that enter the peritoneal cavity during or after peritoneal
