If the bile acids are not reabsorbed into the bloodstream then they enter the large bowel .

Bile acids stimulate secretion in the colon by activating intracellular secretory mechanisms, increasing mucosal permeability, inhibiting Cl / OH exchange and enhancing mucus secretion.20 Colonic water secretion depends on the concentration of bile acids, with concentrations typically > 3 mmol/L leading to secretion.21 Bile acids also stimulate colonic motility by inducing propulsive contractions thereby shortening colon transit time, potentially worsening urgency and diarrhea.22,23 Interestingly, low concentrations of bile acids downregulate colon secretion and promote fluid and electrolyte absorption.24 In contrast, when colonic luminal concentrations of bile acids are high, as is seen in BAM, bile acids induce prosecretory and promotility effects, manifesting clinically as diarrhea. In this test, selenium-75-labeled synthetic bile acid is given orally and, after 7 days, the retained bile acid is measured with a whole-body scan or gamma camera.
