K65-K67: Diseases of peritoneum

Diseases of the peritoneum encompass a group of conditions that affect the thin layer of tissue lining your abdomen, known as the peritoneum. These illnesses can be caused by various factors including infection, injury, or surgical complications. Some common symptoms associated with peritoneal diseases are abdominal pain, swelling, tenderness, and fever. Flaws in the peritoneum can also lead to more serious conditions such as peritonitis, an inflammation of the peritoneum, often caused by a bacterial or fungal infection. This infection can rapidly spread into the blood and to other organs, causing potential severe complications. Diseases of the peritoneum can progressively worsen if not treated promptly, leading to complex health issues such as sepsis or organ failure. These disorders primarily affect the digestive and immune system, leading to disruptions in the body's capacity to digest food and ward off infections.
