Question

Quizplus · Accepted Answer

Glucagon is a hormone that acts as a muscle relaxant in the gastrointestinal tract, particularly in the smooth muscle of the intestinal wall. Therefore, the administration of glucagon shortly before a double-contrast barium enema can help relieve bowel spasm, making the procedure more comfortable for the patient and improving the quality of the images obtained. It does not have any effect on liver function, gallbladder emptying, or bowel motility.
