Cholestasis is a condition where the flow of bile from the liver to the duodenum is impaired. The two basic distinctions are:
- obstructive type of cholestasis, where there is a mechanical blockage in the duct system that can occur from a gallstone or malignancy, and
- metabolic type of cholestasis, in which there are disturbances in bile formation that can occur because of genetic defects or acquired as a side effect of many medications.
Classification is further divided into acute or chronic and extrahepatic or intrahepatic.
