Gestational diabetes

Published: 27/03/2013

Diabetes that develops during pregnancy is known as gestational diabetes. It occurs because your body can’t produce enough insulin (a hormone important in controlling blood glucose) to meet its extra needs in pregnancy. This results in high blood glucose levels. Gestational diabetes usually starts in the middle or towards the end of pregnancy.

This information is for you if you wish to know more about diabetes that develops in pregnancy (gestational diabetes) or have been told that you have gestational diabetes. It tells you:

  • What gestational diabetes is
  • How it is diagnosed
  • What extra antenatal care you can expect
  • What this diagnosis means for you and your baby, now and in the future

This patient information leaflet is based on the National Institute for Health and Care Excellence (NICE) clinical guideline Diabetes in pregnancy and the RCOG Scientific Impact Paper Diagnosis and Treatment of Gestational Diabetes, produced by the Scientific Advisory Committee; the latter contains a full list of the resources used to produce this guidance.
