Can cholestasis of pregnancy cause long term inflammation to common bile duct? Can hormones affect liver enzymes and itching during period?

Possibly. the itching is from the cholestasis as it causes the bike to go up and this causes the itching. The inflammation can persist, but can also resolve. External hormone use has to be processed by liver first, so they can place "pressure" on the liver, as can Tylenol, (acetaminophen) and any other medications typically. .
