Common symptoms of peritonitis

Verywell / JR Bee

If you show any signs of peritonitis, go to the emergency room or call an ambulance right away.

The severity of these symptoms often depends on what caused the inflammation in the first place.

Causes

Peritonitis shows up when body fluids like blood or pus pool in the abdominal cavity.

Why this happens, however, can vary.

The two primary causes of peritonitis are spontaneous bacterial peritonitis (also called primary peritonitis) and secondary peritonitis.

Those with cirrhosis are particularly vulnerable to severe cases of primary peritonitis.

Anywhere from40-70%of adults with cirrhosis who develop SBP die from it.

Examination can be impossible for some patients with severe pain.

For secondary peritonitis, surgery is sometimes necessary to eliminate the source of infection.
