La cholestasis of pregnancy is a rare complication that occurs during pregnancy, most frequently in the third trimester, and is caused by the presence of bile (a natural chemical) in the blood circulation. We talk about cholestasis when hepatocytes (liver cells) do not do their job well and let bile acids pass into the blood instead of dumping them into the bile. The latter accumulate in the blood and risk reaching the fetus via the placenta.
