Postpartum liver function tests (LFTs) significantly change due to delivery and common obstetric events like caesarean sections. Understanding these physiological LFTs aids in differentiating normal changes from illness in new mothers.

Area of Science:

  • Obstetrics and Gynecology
  • Clinical Biochemistry
  • Maternal Health

Background:

  • Liver function tests (LFTs) are crucial for assessing liver health.
  • Postpartum physiological changes in LFTs are not well-defined.
  • Understanding these changes is vital for accurate clinical interpretation in the puerperium.

Purpose of the Study:

  • To investigate changes in liver function tests (LFTs) during the postpartum period.
  • To determine the influence of specific obstetric events on these LFT changes.

Main Methods:

  • A longitudinal observational study involving 94 women with uncomplicated pregnancies.
  • LFTs (AST, ALT, GGT, Bilirubin, ALP) were measured from early labor to 10 days postpartum.
  • Analysis included peak enzyme levels, time to peak, area under the curve, and rate of change.

Main Results:

  • All LFTs significantly changed postpartum, with notable increases in AST, ALT, and GGT.
  • Caesarean section and opioid administration correlated with a faster rise in AST.
  • Caesarean section was associated with higher peak GGT levels compared to vaginal delivery.

Conclusions:

  • Liver enzyme levels undergo significant physiological alterations in the puerperium.
  • Common obstetric interventions, especially caesarean sections, demonstrably affect LFTs.
  • This research provides a baseline for interpreting postnatal LFTs, distinguishing normal variations from pathology.
