What is a common complication of untreated peritonitis?

Sepsis is a common and serious complication of untreated peritonitis due to the bacterial invasion of the bloodstream. Peritonitis typically results from an infection of the peritoneum, often due to the rupture of an internal organ, such as the appendix or a perforated bowel. When the peritoneum becomes infected, bacteria can easily enter the abdominal cavity and may eventually breach the intestinal barrier, leading to sepsis.

Sepsis is characterized by a systemic inflammatory response to infection, which can lead to organ failure and death if not promptly recognized and treated. The progression from localized infection in the peritoneal cavity to a systemic condition further underscores the critical importance of promptly addressing peritonitis with appropriate medical interventions, such as antibiotics and possible surgical correction of the underlying cause.

In contrast, appendicitis, diverticulitis, and cholecystitis are conditions that can cause peritonitis but are not direct complications of it. They may also lead to peritonitis if left untreated, but they are not the typical result of untreated peritonitis itself. Therefore, sepsis stands out as the primary and most concerning complication.
