At each antenatal appointment, your urine will be tested for sugar, which can indicate raised levels of blood glucose. Lots of pregnant women have raised glucose levels without having diabetes, so try not to worry if this happens to you – but you'll probably be referred for more tests.
In many cases, adopting a diet that is high in starchy carbohydrates, fruit and vegetables and low in fat, sugar and salt, will be all that is needed to manage pregnancy diabetes. You may also be advised to eat little and often, to encourage your body to produce insulin, and you'll need regular blood glucose checks to monitor your condition.
In most cases, gestational diabetes doesn't develop until the second trimester, by which time your baby's internal organs have formed, so any risks to him are low.
You're more likely to develop gestational diabetes if you:
- are over 35
- are overweight
- have a family history of diabetes
- had gestational diabetes in a previous pregnancy
- have previously had a big baby
- have had two or more pregnancies already
- are Asian or Afro-Caribbean
