Intrahepatic Cholestasis of Pregnancy
A liver condition of pregnancy causing intense itching
Quick Facts
- Type: Liver condition specific to pregnancy
- Main symptom: Intense itching, often on the hands and feet
- Timing: Usually the third trimester
- Key concern: Increased risk to the baby; needs monitoring
Overview
Intrahepatic cholestasis of pregnancy (ICP) is a liver condition that develops during pregnancy, usually in the third trimester. In ICP, the normal flow of bile from the liver slows down, causing bile acids to build up in the blood. The most noticeable result is intense itching, often without a rash.
While the itching can be very distressing for the mother, the main medical concern is that ICP can increase certain risks for the baby. Because of this, the condition is monitored closely and the timing of delivery may be planned. ICP usually resolves quickly after the baby is born.
ICP is one of the more common liver conditions specific to pregnancy. Although the itching it causes can be relentless, especially at night, recognizing the condition allows the care team to put a clear monitoring plan in place. With close follow-up and a carefully timed delivery, most pregnancies affected by ICP have good outcomes, and the mother's liver returns to normal soon after birth.
Symptoms
The hallmark of ICP is itching, which has some typical features:
- Intense itching, often starting on the palms of the hands and soles of the feet
- Itching that is frequently worse at night and can disrupt sleep
- Itching without a visible rash, though scratching may mark the skin
- Less commonly, dark urine, pale stools, or mild yellowing of the skin and eyes (jaundice)
- Sometimes nausea, loss of appetite, or fatigue
Any persistent itching in pregnancy, especially on the hands and feet, should be reported to a midwife or doctor so it can be checked.
Causes
The exact cause of ICP is not fully understood, but it appears to result from a combination of factors. Pregnancy hormones, especially the rise in estrogen and progesterone, can slow the flow of bile in women who are susceptible. Genetic factors also play a role, since ICP can run in families.
The slowed bile flow allows bile acids to build up in the bloodstream, which causes the itching and the potential risks to the baby. ICP is not caused by anything the mother did, and it is not contagious.
Risk Factors
- A personal or family history of ICP in a previous pregnancy
- Carrying twins or more
- Certain underlying liver conditions
- Pregnancies conceived with assisted reproduction in some cases
Women who have had ICP in one pregnancy are more likely to have it again in future pregnancies.
Diagnosis & Evaluation
ICP is diagnosed by combining symptoms with blood tests:
- Bile acid blood test: Measuring the level of bile acids in the blood is the key test; raised levels support the diagnosis.
- Liver function tests: These check how the liver is working and may be abnormal.
- Ruling out other causes: Doctors consider other liver and skin conditions that can cause itching in pregnancy.
Because results can change, testing may be repeated through the pregnancy to monitor the condition.
Treatment & Management
Management focuses on relieving itching, monitoring the baby, and planning a safe delivery.
- Medication: A medicine called ursodeoxycholic acid is commonly used to help lower bile acids and ease itching.
- Soothing the skin: Cool baths, gentle moisturizers, and loose clothing can help with itching.
- Monitoring: Bile acid levels and the baby's wellbeing are checked regularly during the pregnancy.
- Planned delivery: Depending on bile acid levels and other factors, the care team may recommend planning the timing of delivery to reduce risk to the baby.
After delivery, ICP usually clears, and follow-up confirms that liver tests return to normal. Women who have had ICP are usually advised that it can return in future pregnancies, so they should mention it early to their care team next time so monitoring can begin promptly.
When to See a Doctor
Contact your midwife or doctor promptly if you have persistent itching during pregnancy, especially on the hands and feet or at night. Seek urgent care if you notice:
- Yellowing of the skin or eyes
- Dark urine and pale stools
- A change in your baby's movements or fewer movements than usual
- Feeling very unwell
Reporting these symptoms allows close monitoring and helps protect both mother and baby.
Frequently Asked Questions
What is intrahepatic cholestasis of pregnancy?
It is a liver condition of pregnancy, usually in the third trimester, in which bile flow slows and bile acids build up in the blood. The main symptom is intense itching, often on the hands and feet, usually without a rash.
Is cholestasis of pregnancy dangerous for the baby?
It can increase certain risks for the baby, which is why it is monitored closely and delivery may be planned. Reporting symptoms and attending all checkups helps the care team manage these risks.
What does the itching feel like?
The itching is often intense, may start on the palms and soles, and is frequently worse at night. It usually occurs without a visible rash, although scratching can mark the skin.
How is intrahepatic cholestasis of pregnancy treated?
Treatment may include a medicine called ursodeoxycholic acid to ease itching and lower bile acids, soothing skin measures, regular monitoring of bile acids and the baby, and planning the timing of delivery.
Does cholestasis of pregnancy go away after birth?
Yes. It usually resolves quickly after the baby is born, and liver tests return to normal. However, it can come back in future pregnancies, so women who have had it should let their care team know.
