Intestinal obstruction causes

A. True This is complete when the bowel below the block is empty.

B. True Intermittent colic is typical of early obstruction.

C. True This may be severe when the obstruction is in the lower gut.

D. True Due to hypovolaemia as secretions accumulate in the lumen of the intestines above the obstruction.

E. False Vomiting is worse with high obstruction since the copious upper alimentary secretions cannot be absorbed from the intestines below the obstruction where most absorption normally takes place.
