Women with FH experience the same increase, but since they are starting out at a much higher baseline, they can get extremely high cholesterol during pregnancy. If you become pregnant, stop your statin medications immediately. Fibrates such as feno-brate and gem-brozil are typically not used in patients with FH. These are primarily triglyceride-lowering medications, but if you are on one of these medications, it too should be stopped.
Obstetric cholestasis is a rare condition that only affects you if you are pregnant. In the UK less than 1 in pregnant women will develop it. This slowing of the flow of bile leads to a build-up of bile and some then leaks out into the bloodstream - in particular, the bile salts. Once in the bloodstream they can make your skin very itchy. It is also sometimes called intrahepatic cholestasis of pregnancy ICP and this name is being used more often these days. In the UK less than 1 in pregnant women will develop obstetric cholestasis. It is more common if you are related to someone who has had it in the past - for example, your mother or sister.
