What term is an inflammation of peritoneum?

The term for an inflammation of the peritoneum is peritonitis. Peritoneum is a thin, serous membrane that lines the inner wall of the abdomen and covers most of the abdominal organs. It serves as a protective layer and helps in the movement of organs within the abdominal cavity.

It can cause severe pain, fever, and tenderness in the abdomen, and may lead to complications if left untreated.
