Urobilinogen is a yellow by-product of bilirubin reduction. It is formed in the intestines by the bacterial enzyme bilirubin reductase. [ 1 ] About half of the urobilinogen formed is reabsorbed and taken up via the portal vein to the liver, enters circulation and is excreted by the kidney.
Part of the urobilinogen is reabsorbed in the intestine then circulated in the blood to the liver where it is excreted. A small part of this recirculated urobilinogen is filtered out by the kidneys and appears in urine (less than 1 mg/dL urine). The stercobilinogen can not be reabsorbed and remains in the intestine.

Bilirubin is then excreted as bile, which is further degraded by microbes present in the large intestine to urobilinogen. The enzyme responsible for the degradation is bilirubin reductase, which was identified in 2024. [1] [2] Some of this remains in the large intestine, and its conversion to stercobilin gives feces their brown color. Some is ...

Conjugated bilirubin is then secreted along with bile into the intestine and is either excreted in faeces as urobilinogen or reabsorbed into blood and transported back to the liver. The varied causes of hyperbilirubinemia are best understood from bilirubin metabolism.
