What is meant by cholestasis?
What is meant by cholestasis?
Cholestasis is defined as a decrease in bile flow due to impaired secretion by hepatocytes or to obstruction of bile flow through intra-or extrahepatic bile ducts. Therefore, the clinical definition of cholestasis is any condition in which substances normally excreted into bile are retained.
What is the pathophysiology of cholestasis?
Cholestasis results from defective canalicular secretion of bile or obstruction to bile flow distal to the canaliculus. In early primary biliary cirrhosis, bile secretion continues, because of the secretory pressure of bile or because some ductules are not obstructed.
What can cause cholestasis?
What Causes Cholestasis?
- Viral hepatitis.
- Alcoholic liver disease.
- Inflammation of the bile ducts — pipes that transport bile (primary biliary cholangitis)
- Cancer that gets to your liver.
- Bacterial infection (sepsis)
- Certain genetic disorders, like sickle cell disease.
- Hodgkin’s and non-Hodgkin’s lymphoma.
What may protect hepatic cells from cholestasis?
Reduced hepatobiliary bile acid transport due to loss of BSEP function leads to increased hydroxylation of bile acids in the liver. Metabolic preconditioning with a hydrophilic bile pool protects the BSEP−/− mice from acquired cholestatic liver disease.
Why is urine dark in cholestasis?
Symptoms of Cholestasis Jaundice is a yellow color of the skin and eyes that results from excess bilirubin deposited in the skin, and dark urine results from excess bilirubin excreted by the kidneys.

How is cholestasis diagnosed?
A doctor diagnoses cholestasis of pregnancy with a physical examination and blood tests. These tests tell the doctor how the liver is functioning. They also measure the level of bile acids in the blood. Tests confirm the diagnosis when total bile acids measure 10 micromoles per liter and above.
How do you relieve cholestasis?
Treatment
- Taking a prescription drug called ursodiol (Actigall, Urso, Urso Forte), which helps to lower the level of bile in your blood. Other medications to relieve itching may also be an option.
- Soaking itchy areas in cool or lukewarm water.
