Overview
The main manifestations of peritonitis are acute abdominal pain, tenderness, and guarding, which are exacerbated by moving the peritoneum, e.g. coughing, flexing the hips, or eliciting the Blumberg sign (a.k.a. rebound tenderness, meaning that pressing a hand on the abdomen elicits pain, but releasing the hand abruptly will aggravate the pain, as the peritoneum snaps back into place).
Abdominal pain and tenderness: The localization of these manifestations depends on whether peritonitis is localized (e.g. appendicitis or diverticulitis before perforation), or generalized to the whole abdomen; even in the latter case, pain typically starts at the site of the causing disease. Peritonitis is an example of acute abdomen.
Common Symptoms of SBP

- Fever
- Worsening of pre-existing ascites and progressive encephalopathy in a patient with cirrhotic ascites
- Development of ileus paralyticus (i.e. intestinal paralysis), which also causes nausea and vomiting
