The thresholds GPs use for diagnosing pregnant women with gestational diabetes should be lowered, according to updated NICE guidelines.

It is being advised that if a pregnant woman has a fasting plasma glucose level of 5.6 mmol/litre or above, or a 2-hour plasma glucose level of 7.8 mmol/litre or above they should be diagnosed.

Around 35,000 women have either pre-existing or gestational diabetes each year in England and Wales.

Nearly 90 per cent of the women who have diabetes during pregnancy, have gestational diabetes, which may or may not resolve after pregnancy. Rates have increased in recent years to due rising obesity rates among the general population, and increasing number of pregnancies among older women.

Of the women with diabetes in pregnancy who do not have gestational diabetes, 7.5 per cent of women have Type 1 diabetes, and the remainder have Type 2 diabetes, both of which have also increased recently.

Following a number of developments, such as new technologies and research on diagnosis and treatment of gestational diabetes, NICE has updated its guidelines on diabetes in pregnancy.
