Yes, this pattern is very likely obstetric cholestasis of pregnancy. Whole-body itching in the third trimester, often worst on the palms and soles and worse at night, along with a bile acid level of 28.8 µmol/L, meets the diagnostic threshold in most protocols. It is very treatable and usually managed with ursodeoxycholic acid alongside close monitoring of the baby.
Next Steps
Please connect with your obstetrician urgently if this has not already been flagged. Management usually involves twice-weekly non-stress tests from around 32 weeks, weekly bile acid rechecks, and often a planned delivery between 37 and 38 weeks depending on how the levels trend.
Health Tips
Please do not delay the review or self-medicate with antihistamines just to control the itch. Cholestasis needs specific treatment, and monitoring the baby is the more important half of the plan.
