Intrahepatic Cholestasis of Pregnancy (ICP)

Liver condition causing severe itching, usually in third trimester, increasing stillbirth risk.

Affects: 1-2% of pregnancies in US, higher in certain populations

Overview

Intrahepatic cholestasis of pregnancy (ICP) is a liver condition where bile acids build up in the bloodstream instead of flowing from the liver to the gut. This causes intense itching, especially on hands and feet, typically in the third trimester.

The main concern with ICP is increased risk of stillbirth and preterm birth. The exact mechanism isn't fully understood, but elevated bile acids can affect the baby. Treatment includes medication to lower bile acids and close monitoring.

Most cases resolve shortly after delivery. Women with ICP typically deliver between 36-38 weeks to reduce stillbirth risk while avoiding unnecessary prematurity.

🩺 Symptoms

  • Intense itching, especially on palms and soles
  • Itching worse at night
  • No rash (unless from scratching)
  • Dark urine
  • Light-colored stools
  • Jaundice (rare)
  • Fatigue beyond normal pregnancy
  • Loss of appetite
  • Nausea

🔍 Causes

  • Exact cause unknown
  • Pregnancy hormones affecting liver function
  • Genetic factors (runs in families)
  • Bile acid buildup in blood
  • Liver not processing bile acids properly

⚠️ Risk Factors

  • Personal or family history of ICP
  • Previous liver damage
  • Multiple pregnancy
  • Hispanic, Scandinavian, or Chilean descent
  • IVF pregnancy
  • Hepatitis C infection

🔬 Diagnosis

  • Blood test for bile acids (elevated)
  • Liver function tests (may be elevated)
  • Clinical symptoms (severe itching)
  • Ruling out other causes of itching
  • Bile acids usually over 10 micromol/L
  • Severity based on bile acid levels

💊 Treatment

  • Ursodeoxycholic acid (UDCA) - reduces bile acids and improves outcomes
  • Anti-itch medications (limited effectiveness)
  • Vitamin K supplementation
  • Frequent monitoring of bile acids and liver function
  • Fetal monitoring (non-stress tests, biophysical profiles)
  • Early delivery at 36-37 weeks
  • May induce labor to prevent stillbirth
  • Symptoms resolve shortly after delivery

🛡️ Prevention

  • Cannot be prevented
  • Early recognition and treatment important
  • If previous ICP, monitoring in subsequent pregnancies
  • May recur in 60-90% of future pregnancies

⚠️ Potential Complications

  • !Stillbirth (main concern)
  • !Preterm birth
  • !Meconium in amniotic fluid
  • !Fetal distress during labor
  • !Maternal vitamin K deficiency
  • !Postpartum hemorrhage
  • !Gallstones later in life
  • !Increased liver disease risk
  • !Recurrence in future pregnancies

🚨 When to Call Your Doctor

Contact your healthcare provider immediately if you experience:

  • Severe itching, especially hands and feet
  • Itching that worsens or doesn't improve
  • Dark urine or light stools
  • Yellowing of skin or eyes
  • Decreased fetal movement
  • Any new symptoms
  • Don't dismiss itching as "just pregnancy" - get tested
