==Symptoms==
Patients can remain asymptomatic for very long periods of time. As larval stages travel through the body, they may cause visceral damage, [[peritonitis]] and [[inflammation]], enlargement of the [[liver]] or [[spleen]], toxicity, and [[pneumonia]].  A heavy worm infestation may cause nutritional deficiency; other complications, sometimes fatal, include obstruction of the bowel by a bolus of worms (observed particularly in children) and obstruction of the [[bile]] or [[pancreas|pancreatic]] duct.  More than 796 Ascaris lumbricoides worms weighing 550 [[gram|g]] [19 ounces] were recovered at autopsy from a 2-year-old South African girl. The worms had caused torsion and gangrene of the [[ileum]], which was interpreted as the cause of death{{ref|6}}.
 
Ascaris takes most of its nutrients from the partially digested host food in the [[intestine]].  There is limited evidence that it can also pierce the intestinal mucous membrane and feed on blood, but this is not its usual source of nutrition.[http://www.path.cam.ac.uk/~schisto/Nematodes/Ascaris.html]  As a result, Ascaris infection does not produce the[[anemia]] associated with some other [[roundworm]] infections.
