Gestational diabetes occurs when the body can’t manage blood sugar as effectively during pregnancy. Hormones from the placenta make the body more resistant to insulin, and some people cannot produce enough extra insulin to compensate. This results in higher blood sugar levels. Most people have no symptoms and are diagnosed through glucose testing at 24–28 weeks.

A diagnosis is not your fault. It reflects how your body responds to the demands of pregnancy. The main goal is to keep blood sugar stable, as this reduces risks such as high birth weight, induction, caesarean birth, or low blood sugar in the newborn.

Most can manage gestational diabetes through diet, regular meals, and gentle physical activity. You’ll receive support from a midwife and sometimes a diabetes team to find routines that work. Some need insulin, which is completely safe for both you and the baby.

Gestational diabetes affects follow-up later in pregnancy. Extra growth scans are often done, and sometimes induction is recommended around the due date if the baby is large or blood sugar is difficult to control. After birth, the baby’s blood sugar is monitored, and you will be offered a repeat glucose test a few months postpartum.

Gestational diabetes almost always resolves after birth, but the long-term risk of type 2 diabetes is slightly higher. Healthy routines after pregnancy help reduce that risk.
