A 40 year old woman had undergone surgical ileal resection due to perforation caused by severe Crohn's disease. Which of the following physiological change occurs now?
Absorption of amino acids is rapid in the duodenum and jejunum. There is a little absorption in the ileum in health because the majority of the free amino acids have already been assimilated at that point. Almost all iron absorption occurs in the duodenum. One cause of steatorrhea is defective reabsorption of bile acids in the distal ileum. When bile acid reabsorption is prevented by resection of the terminal ileum or by disease in this poion of the small intestine, the amount of fat in the stools is also increased because when the enterohepatic circulation is interrupted, the liver cannot increase the rate of bile acid production to a sufficient degree to compensate for the loss. Almost all iron absorption occurs in the duodenum. Reference: Ganong's Review of Medical Physiology; 25th edition; Page no: 480,482,484
A decrease in absorption of amino acids
An increase in the absorption of iron
An increase in the concentration of bile acid in the enterohepatic circulation
An increase in the water content of the faeces
