How does the weak yang of urobilinogen cause

Urobilinogen is weakly positive and needs to be analyzed in conjunction with symptoms to determine the cause. In most cases it may be a nonspecific transient increase that does not require special attention. In pathological conditions, it is often seen in hepatobiliary problems. Bilirubin disorders due to internal and external diseases of the liver and biliary tract include unconjugated bilirubin and conjugated bilirubin retained in the blood, the latter being soluble in water. Part of it is excreted in urine as urinary bilirubin. Conjugated bilirubin enters the intestine and is converted into urobilinogen. Most urobilinogen is absorbed from the intestine and is reconverted into conjugated bilirubin and discharged into the intestine. A small part is eliminated from glomerular filtration and renal tubules, followed by urobilinogen in urine. Urobilinogen becomes urobilin when contacted with air. Urinary bilirubin, urobilinogen and urobilin are collectively called urinary bile. Urinary bilirubin and urinary infection are called urinary bile. Weak positive or increased urobilinogen, often seen in hepatocellular jaundice and hemolytic jaundice. Reduced urobilinogen, often seen in cholestasis jaundice.
