Peritonitis is an inflammation of the peritoneum, which is the membrane that lines the wall of the abdomen and covers the abdominal organs.
Causes, incidence, and risk factors
- Spontaneous Peritonitis – An infection that occurs as a complication of ascites (a collection of fluid in the peritoneal cavity), which is usually related to liver or kidney failure
- Secondary Peritonitis – Caused by another condition, most commonly the spread of an infection from the digestive organs or bowels
- Dialysis-associated Peritonitis – This is an acute or chronic inflammation (irritation and swelling) of the peritoneum (lining of the abdominal cavity) that occurs in people receiving peritoneal dialysis
- Intra-abdominal abscess (abdominal abscess) – This condition involves a collection of pus in the abdomen and may cause peritonitis. Before peritonitis develops, it can still cause symptoms that are similar or identical to peritonitis.
