Cholestasis of pregnancy, also called intrahepatic cholestasis of pregnancy (ICP), is a pregnancy-related condition in which impaired bile flow can raise bile acids in your blood. [1][2] It often appears later in pregnancy and should be assessed by your pregnancy care clinician. [2]
Knowing the name and basic meaning can help you describe the concern clearly when you talk with your care team. The term “ICP” is simply another name you may hear for cholestasis of pregnancy. [2] This overview explains what the condition is, what signs and assessment may involve, and which care decisions are best discussed with your clinician.
The key point is that a possible diagnosis is a reason to involve your pregnancy care clinician, rather than trying to interpret it on your own. They can consider your situation and explain what the next steps mean for you. The sections below offer a starting point for understanding the condition and preparing for those conversations.
What happens to bile during pregnancy?
Bile is a digestive fluid made by your liver, and it helps your body digest food. [3] During pregnancy, cholestasis disrupts the normal movement of bile, so bile acids can build up in your body. [1][4] For a closer look, read Cholestasis of Pregnancy Diagnosis: Tests and Follow-Up.
Bile’s usual role
Your liver makes bile as part of digestion. [3] Think of it as a fluid that supports the process of breaking down food; it is not the same thing as the food itself. [3] The key point is that bile needs to move normally for its digestive role, while cholestasis means that its flow is reduced or stopped. [3]
What changes with cholestasis
When bile flow is impaired, bile acids may accumulate rather than move through the usual pathway. [1][4] This is a change in how bile moves, not simply a change in what you eat. The condition involves the liver’s handling of bile during pregnancy. [4]
The exact cause of cholestasis of pregnancy is unclear. [3] Pregnancy-related hormones may play a part, as the condition is described as hormonally influenced. [5] That possibility does not identify one single cause for every pregnancy; it helps explain why the condition is linked to changes that happen during pregnancy. [3][5]
Understanding the basic process can make the name less confusing: cholestasis refers to disrupted bile flow, and the resulting buildup involves bile acids. [1][3][4]
What signs should prompt a call to your care team?
Itching during pregnancy is worth mentioning to your care team, especially if it is new or does not go away. Cholestasis of pregnancy often causes severe itching, and skin changes may also occur. [2][6]
The itch can be uncomfortable or worrying, but you do not need to decide for yourself what is causing it. Contact your pregnancy care team and describe when it began and whether it is continuing; for example, you might say, “I’ve developed itching that hasn’t settled.”
You can call even if you do not see a skin change. Itching is a common symptom, and yellowing of the skin may also occur with cholestasis of pregnancy. [2][6] If you notice a change in your skin or have persistent itching, include that detail when you reach out.
Keep your message simple and specific: explain what you have noticed and how long it has been happening. If you are unsure whether it is worth a call, contact your care team and ask what they recommend for your situation.
A call is a practical first step, not a diagnosis. Your care team can advise you on what to do next based on your symptoms and pregnancy.
How can it affect pregnancy?
Raised bile acids make cholestasis relevant to pregnancy care, but what it means for you depends on your individual pregnancy and clinical findings. Elevated bile acids in the maternal bloodstream are a feature of the condition. [1]
Your care team considers the findings in your case when discussing possible effects and next steps. For example, your situation may differ from another pregnant person’s based on the clinical picture; there is no single plan that applies to everyone. [4]
Avoid trying to predict your pregnancy’s outcome from the diagnosis alone. Instead, ask your clinician what your own findings mean and how they shape your care plan. [4]
If you are concerned about possible effects, bring that concern to your pregnancy care clinician and ask for an explanation tailored to you. You can also ask what factors they are considering, rather than relying on a general estimate or assuming a particular outcome. [4]
What should you ask your clinician?
Bring a short list of questions to your appointment so you can understand what your symptoms and test findings mean for your pregnancy. Your care team can explain how the results fit together and what they suggest for your individual situation.
Questions about your results
You might ask, “What do my test findings mean for my pregnancy?” or “Do the results change what you recommend next?” If you are unsure what a result or medical term means, ask your clinician to explain it in everyday language and tell you what to watch for before your next visit.
Questions about follow-up
Ask what follow-up or monitoring your care team recommends, and when you should expect to hear about the next step. For example, you could ask whether they want to repeat or review anything, who will contact you with updates, and whom to call if you have a new question.
Questions about treatment and birth timing
Ask how treatment options will be considered for your circumstances, including what each option is intended to address and what factors would affect the plan. You can also ask how your clinician will decide whether and when to discuss birth timing, and what findings or changes might prompt another conversation.
It may help to write down your questions before the visit and bring a support person if you would like help remembering the answers. Before you leave, repeat back the plan in your own words and ask whom to contact if anything is unclear.
Common questions about cholestasis of pregnancy
Is cholestasis of pregnancy the same as ICP?
Yes. ICP stands for intrahepatic cholestasis of pregnancy, another name for cholestasis of pregnancy. [2] You may see either term in conversations or paperwork about your care, and they refer to the same condition.
Does cholestasis of pregnancy always cause itching?
No. Itching is common, but symptoms can vary. [2] For example, you may have itching without other noticeable symptoms, or your experience may not match someone else’s. If you are unsure what a symptom means, share it with your pregnancy care clinician rather than trying to compare it with another person’s experience.
Can you decide treatment or delivery timing on your own?
No. Talk through treatment and birth-timing plans with your pregnancy care clinician, who can help consider your circumstances. A plan that is appropriate for one pregnancy may not suit another, so avoid starting, stopping, or changing care on your own. Bring questions about your options to an appointment; for instance, ask what the proposed plan means for you and when you should check back with the team.
What if your symptoms or plans change?
Let your care team know if symptoms change or if you have questions about the plan. You can write down what you notice and the questions you want answered, then use that list when you contact the office or attend an appointment. This can help keep the conversation focused on what you need to know.
A steady next step if you are concerned
If itching worries you or keeps coming back, contact your pregnancy care team and ask what next step makes sense for you. You do not need to decide on your own whether it points to cholestasis of pregnancy; your clinician can help you consider your symptoms and situation. [2]
A simple message or call can get the conversation started. You might say, “I’m concerned about itching that hasn’t gone away. Should I be assessed, and what should I do next?” If you have already spoken with your team, let them know if your concern continues and ask when to check in again.
Bring your questions about evaluation, follow-up, and care planning to that conversation. For example, you can write them down beforehand or keep a note on your phone, then ask what the next steps would involve and when you should expect to hear from the team. You can also ask whom to contact if you have more concerns.
Your care plan should be discussed with your clinician, because decisions depend on your individual pregnancy and clinical findings. [2] It is reasonable to ask for an explanation of the options and how the team will make decisions with you. The main thing to remember is that you can raise a concern and ask for guidance rather than trying to work out a plan by yourself.
