'''Peritonitis''' is the inflammation of a membrane within the [[abdomen|abdominal cavity]]. Causes can be from a variety of complications, such as intestinal parasites and [[fever]], which can become serious threat to the life of the individual and should be immediately remedied by either surgery or [[antibiotics]].

'''Peritonitis''' is the inflammation of the peritoneum, a membrane within the [[abdomen|abdominal cavity]]. Causes are divided into infective (such as bacteria and parasites), and non-infective (such as leakage of gastrointestinal contents and toxic causes).  If left untreated, peritonitis can rapidly become a serious threat to life, commonly from [[sepsis]], as well as buildup of fluid or formation of [[abscess]]es.

Complications of peritonitis can be serious - [[sepsis]], buildup of fluid or [[abscess]]es (which may inhibit proper breathing), shock, and possible [[renal failure]].

Peritonitis is commonly treated initially with supportive care (fluid resuscitation, oxygen, analgesia), antibiotics (including those, such as metronidazole, which cover anaerobic bacteria common to the gut), and in severe cases surgery (laparotomy to identify and treat the source of the peritonitis).

General peritonitis, if untreated, is almost always fatal. About 10% or more of all patients have perished under surgical treatment and the percentage increases with age.

The complications of peritonitis carry a significant mortality rate, due to septic [[shock]] and organ failure. In the US and western Europe, death from peritionitis occurs in around 10% of all cases, rising to over 40% in the elderly.  Mortality and morbidity rates are significantly higher in non-industrialised countries where access to adequate medical facilities and medicines prevent adequate treatment.
