What is absorbed in the terminal ileum?

Vitamin B12 and bile salts are absorbed in the terminal ileum. Water is absorbed by osmosis and lipids by passive diffusion throughout the small intestine.

Why does ileal resection cause steatorrhea?

When greater than 100 cm of ileum is lost to surgical resection or disease, the daily loss of bile acids exceeds the ability of the liver to synthesize new bile acids; hence, the total circulation bile acid pool is diminished. Bile acid deficiency leads to impaired intraluminal micellar fat absorption or steatorrhea.
