Jaundice in pregnancy
Obstetric cholestasis / pregnancy-specific liver disease
Overview
Jaundice or deranged liver function in pregnancy — most commonly intrahepatic cholestasis of pregnancy (obstetric cholestasis): pruritus (esp. palms/soles) WITHOUT a rash and raised bile acids, carrying a risk of stillbirth.
Recognise
- Intense PRURITUS, classically palms and soles, WITHOUT a primary rash, often worse at night
- Raised serum bile acids ± raised transaminases
- May have mild jaundice; resolves after delivery
Red flags
- Very high bile acids (stillbirth risk); features of pre-eclampsia/HELLP or acute fatty liver of pregnancy (a different emergency)
Differentials & how to tell them apart
Investigations
Serum BILE ACIDS + LFTs; exclude other causes (viral hepatitis serology, USS liver/biliary). Monitor fetal wellbeing.
Management
Ursodeoxycholic acid + bile-acid monitoring + planned delivery timing
- 1Obstetric cholestasis: check bile acids/LFTs, exclude other causes, ursodeoxycholic acid for itch, monitor bile acids and fetal wellbeing.Gate: Very high bile acids → consider earlier planned delivery (stillbirth risk rises with bile-acid level)
- 2Resolves after delivery — recheck LFTs postnatally; high recurrence in future pregnancies; avoid oestrogen contraception if it triggered itch.
Key points
Itching of palms and soles WITHOUT a rash = obstetric cholestasis until proven otherwise. Distinguish from acute fatty liver of pregnancy (an emergency with hypoglycaemia/coagulopathy).
Monitor & prognosis
Bile acids, LFTs, fetal surveillance; postnatal LFT resolution.
Maternal resolution after delivery; fetal risk drives timing.
