Summary

Gallstone formation risk increases with more pregnancies, with most stones developing in the second or third trimester. This study tracked gallstones in 669 women during pregnancy and lactation.

Area of Science:

  • Obstetrics and Gynecology
  • Gastroenterology
  • Hepatology

Background:

  • Gallstones (cholelithiasis) are common, with pregnancy being a known risk factor.
  • Changes in gallbladder function and bile composition occur during pregnancy.
  • Understanding the timing and risk factors for gallstone formation is crucial for maternal health.

Purpose of the Study:

  • To determine the incidence of gallstone formation during pregnancy and lactation.
  • To identify the gestational timing of gallstone appearance.
  • To investigate changes in predisposing factors for gallstones.

Main Methods:

  • Prospective study involving 669 pregnant women in Greece.
  • Utilized real-time ultrasonography and biochemical markers (lipids, liver enzymes).

  • Measurements taken at multiple points during pregnancy and postpartum.

    • Main Results:

    • 2% of women developed gallstones, primarily during pregnancy (13/14).
    • A history of 3 or more pregnancies significantly increased gallstone risk (5% vs 1%).
    • Gallbladder volume doubled, and cholesterol/triglyceride levels rose during pregnancy.

    Conclusions:

    • The number of pregnancies is a significant risk factor for gallstone development.
    • Most gallstones form during the second or third trimesters of pregnancy.
    • Gallstone formation is linked to pregnancy-induced physiological changes.
