Introduction

The peritoneum is a silk-like membrane that lines your inner abdominal wall and covers the organs within your abdomen. Peritonitis is a bacterial or fungal infection of this lining. The infection may come from fluid buildup within the peritoneum, from another infection, inflammation or injury within your body, or it may be a complication of peritoneal dialysis.

Whatever the cause, peritonitis requires prompt medical attention to fight the infection and, if necessary, to treat any underlying medical conditions. Treatment of peritonitis usually involves antibiotics and, in some cases, surgery. If left untreated, peritonitis can lead to severe infection throughout your body, which may become life-threatening.

If you're receiving peritoneal dialysis, you can help prevent peritonitis by following good hygiene before, during and after dialysis.
