Non function colon: Toxic megacolon can be the end result of many conditions. Most common would be a severe acute attack of ulcerative colites or c. Diff colites causing a severe infection and ischemia (lack of adequate microvascular blood flow) which leads to a massively dilated and a non functioning colon...This is a serious condition which many times needs emergent surgery. Hope this helps.

Dilated, sick: Toxic megacolon is a dilation of the colon above 6 cm. It is typically associated with signs of severe illness (such as increased heart rate, fever, etc). It is diagnosed by a thorough assessment by your doctor and abdominal x-rays. It is a serious condition that often requires surgery.
