==Signs and symptoms==
Early symptoms can include periodic abdominal pain, [[nausea]], [[vomiting]] (sometimes green in color from [[bile]]), pulling legs to the chest area, and intermittent moderate to severe cramping [[abdominal pain]]. Pain is intermittent—not because the intussusception temporarily resolves, but because the intussuscepted bowel segment transiently stops contracting. Later signs include [[rectal bleeding]], often with "red currant jelly" stool (stool mixed with blood and mucus), and lethargy. Physical examination may reveal a "sausage-shaped" mass, felt upon [[palpation|palpating]] the abdomen.<ref name=Cera>{{cite journal|author=Cera, SM|title=Intestinal Intussusception|journal=Clin Colon Rectal Surg|date=2008|volume=21|issue=2|pages=106–13|pmid=20011406|issn=1531-0043|doi=10.1055/s-2008-1075859|pmc=2780199}}</ref> Children, or those unable to communicate symptoms verbally, may [[cry]], draw their knees up to their chest, or experience [[dyspnea]] (difficult or painful breathing) with paroxysms of pain.In neonates it can present with bilious vomiting and blood in stool<ref></ref>.
[[Fever]] is not a symptom of intussusception. However, intussusception can cause a loop of bowel to become [[Necrosis|necrotic]], secondary to [[ischemia]] due to compression to arterial blood supply. This leads to perforation and [[sepsis]], which causes fever.
