What does gestational diabetes mean in pregnancy?

The placenta produces hormones that support the pregnancy, but these hormones can make it harder for insulin to move glucose from the blood into cells. The result is raised blood glucose. Gestational diabetes is different from diabetes that was present before pregnancy, although both need careful monitoring.

Many people have no noticeable symptoms, so screening and routine antenatal checks matter. When glucose stays above the target set for you, your maternity team may discuss food choices, activity that is suitable for your pregnancy, home glucose checks and medication if needed. Keeping appointments helps the team follow your health and your baby's growth.

Ask when you should test, whether you need to record readings, and what your personal glucose targets are. Eat regular meals and follow the plan provided by your maternity team rather than making major dietary changes alone. Gentle activity may be appropriate for some pregnancies, but check first if you have pain, bleeding, contractions or another pregnancy complication.

Bring your glucose records and questions to each appointment. The care plan can change as pregnancy progresses, and treatment decisions depend on your readings, overall health and the baby's growth.

Contact your maternity team promptly if your readings are repeatedly outside your agreed range, you cannot keep fluids down, or you feel unusually weak, confused or very unwell. Seek urgent maternity help for heavy bleeding, severe abdominal pain, severe headache with vision changes, or reduced baby movements after you have been advised how to monitor them.

Ask: When should I check my glucose? What should I do if a reading is outside my target? Which foods and activities fit my pregnancy? Will I need additional checks of my baby's growth? How will the plan change after birth?
