Pregnancy-Related Intrahepatic Cholestasis
What is Pregnancy-Related Intrahepatic Cholestasis?
Pregnancy-related intrahepatic cholestasis is a liver condition that develops during pregnancy. It happens when bile flow from your liver slows down or stops completely. Bile is a digestive fluid that helps break down fats in your intestines.
When bile cannot flow normally, bile acids build up in your bloodstream. This causes intense itching, usually starting on your palms and feet. The condition typically appears in the third trimester of pregnancy. It goes away within days or weeks after delivery.
This condition affects about 1 in 1,000 pregnancies in the United States. It is more common in women carrying twins or multiples. While the itching can be unbearable, the bigger concern is the risk to your baby. High bile acid levels can increase the chance of premature birth and stillbirth.
Symptoms
- Severe itching on palms of hands and soles of feet
- Itching that spreads to arms, legs, and torso
- Itching that worsens at night and disrupts sleep
- Dark urine that looks like tea or cola
- Pale or clay-colored stools
- Yellowing of skin or eyes, called jaundice
- Loss of appetite or nausea
- Fatigue beyond normal pregnancy tiredness
Some women experience only itching without other visible symptoms. The itching usually starts after week 28 of pregnancy. It can appear suddenly and become severe within days.

Causes and risk factors
The exact cause of pregnancy-related intrahepatic cholestasis is not fully understood. Pregnancy hormones, especially estrogen, seem to affect how your liver processes bile. Genetic factors play a role, as the condition often runs in families. Women who have had it in one pregnancy are more likely to develop it again in future pregnancies.
Risk factors include carrying twins or multiples, a history of liver damage, and having a mother or sister with the condition. Women of Chilean or Scandinavian descent have higher rates. Previous use of birth control pills that caused itching may also increase risk. The condition is more common in winter months for reasons that are not clear.
How it's diagnosed
Diagnosis starts with blood tests that measure liver enzymes and bile acid levels. Rite Aid offers testing for liver enzymes including Gamma-Glutamyl Transferase, which helps confirm cholestatic liver dysfunction during pregnancy. Your doctor will look at your liver function panel to check for elevated enzymes that indicate bile flow problems.
Bile acid testing is the most specific test for this condition. Levels above 10 micromoles per liter suggest intrahepatic cholestasis. Your doctor may also order additional liver function tests to rule out other liver conditions. Ultrasound can help exclude gallstones or other structural problems. Early diagnosis is important because it allows your medical team to monitor your baby closely.
Treatment options
- Ursodeoxycholic acid medication to reduce bile acid levels and relieve itching
- Vitamin K supplements to prevent bleeding problems in mother and baby
- Frequent fetal monitoring with non-stress tests and biophysical profiles
- Early delivery, often between 36 and 38 weeks, to reduce stillbirth risk
- Cool baths and calamine lotion to provide temporary itch relief
- Avoiding hot showers and tight clothing that can worsen itching
- Oatmeal baths or moisturizers without fragrances for skin comfort

Frequently asked questions
Most cases start in the third trimester, usually after week 28 of pregnancy. Some women develop symptoms earlier, especially if they have had the condition before. The itching often begins suddenly and becomes severe within a few days. Symptoms disappear quickly after delivery, usually within 2 to 3 days.
Bile acid testing is the primary diagnostic test, with levels above 10 micromoles per liter indicating the condition. Liver enzyme tests including Gamma-Glutamyl Transferase help confirm cholestatic liver dysfunction. Your doctor may also check bilirubin levels and other liver function markers to rule out other conditions.
If you have had it once, you have a 60 to 80 percent chance of developing it again in future pregnancies. The condition tends to appear earlier and may be more severe in subsequent pregnancies. Let your doctor know about your history so monitoring can start early. Some women choose to avoid pregnancy after severe cases.
Cool baths, loose cotton clothing, and keeping your home cool can provide some relief. Avoid hot water and harsh soaps that dry out skin. Some women find oatmeal baths or calamine lotion helpful. Unfortunately, regular anti-itch creams do not work well because the problem is internal, not skin-related.
Your liver function returns to normal within days to weeks after delivery. The itching usually stops within 2 to 3 days. Follow-up blood tests at 6 to 12 weeks after birth can confirm your liver enzymes and bile acids are back to normal. The condition does not cause permanent liver damage in most cases.
There are no specific foods that cure or worsen the condition. However, eating a balanced diet supports overall liver health during treatment. Some doctors recommend reducing fatty foods since bile helps digest fat. Focus on whole foods, vegetables, lean proteins, and staying hydrated. Talk to your doctor about any dietary concerns.
