K65: Peritonitis

K65.0: Acute peritonitis

Acute peritonitis is a sudden inflammation of the peritoneum, the thin tissue layer that lines the internal wall of your abdomen and covers the organs within your abdominal cavity. This condition often occurs as a result of infection, typically due to a rupture or perforation in your abdominal area, such as a burst appendix. It may also arise in relation to other abdominal problems such as diverticulitis or peptic ulcer disease. Common symptoms include severe, continuous abdominal pain that worsens when you move, fever, nausea and a noticeable change in bowel movements or inability to pass gas. If left untreated, acute peritonitis can lead to serious, potentially life-threatening complications. It's important to promptly identify and address the underlying cause to manage this condition effectively.
