    Alternative Names

    Spontaneous bacterial peritonitis (SBP)


    Causes, incidence, and risk factors

    Spontaneous peritonitis is usually caused by infection of ascites, a collection of fluid in the peritoneal cavity. This usually occurs from liver or kidney failure.

    Risk factors for liver disease include excessive alcohol use and other diseases that lead to cirrhosis, such as chronic viral hepatitis (hepatitis B or hepatitis C ).

    Spontaneous peritonitis also occurs in patients who are on dialysis for kidney failure.
