Gestational diabetes affects about 4-5% of pregnancies in the UK, according to Diabetes UK. All pregnant women are screened for risk factors for gestational diabetes at 8-12 weeks of gestation when they are booked in for their pregnancy. If they have more than one risk factor, they are offered an oral glucose tolerance test around 24-28 weeks of gestation. They will be offered a test earlier if they have previously had gestational diabetes and a further one at 24-28 weeks if that first test is normal.
