What is gestational diabetes?
The hormone insulin moves glucose or sugar from your blood and into your body’s cells, where it is used for energy. When you have diabetes, this process is blocked and your cells become “insulin resistant”. This causes you to have too much glucose in your blood. In pregnancy, the hormones from the placenta, which help your baby to grow, can cause your cells to become insulin resistant. Usually in pregnancy the body produces more insulin to counter this but in some mothers this doesn’t happen and they develop gestational diabetes.
