Can pregnancy affect blood sugar levels?

Published: 2026-08-10

Key Takeaways

  • Placental hormones increase insulin resistance during pregnancy.
  • Screening is done between 24 and 28 weeks of gestation.
  • Fasting Blood Sugar and OGTT are routine screening tests.

Pregnancy causes placental hormonal changes that make body cells more resistant to insulin, increasing gestational diabetes risk.


Gestational Diabetes Mellitus (GDM) occurs when pregnancy hormones interfere with maternal insulin function.
