2. Cause: Spontaneous Peritonitis

Although it is less common, you can develop peritonitis without having an abdominal rupture. Known as spontaneous peritonitis, this type occurs as a complication of another underlying disease such as cirrhosis of the liver. Along with liver disease, kidney failure can also lead to peritonitis. If you require peritoneal dialysis to rid your blood of waste products, you have a higher risk of contracting peritonitis because of accidental contamination of the catheter.
