Concern rises for missed diabetes testing - that could mean TWO THIRDS of pregnant women are going undiagnosed By Meike Leonard Published: 23:02, 21 September 2024 | Updated: 23:28, 21 September 2024 e-mail View comments Two thirds of pregnant women could be going undiagnosed with a serious medical condition due to faulty screening, according to research. A study found that widely used tests for gestational diabetes – which causes high blood sugar and usually occurs in the second and third trimesters of pregnancy – only correctly identify 29 per cent of cases. If left untreated, the condition can cause pregnancy complications for both mother and baby – including an increased risk of both developing type II diabetes, babies growing larger than usual and premature birth.
Although rare, it can also cause babies to be stillborn. As a result, the NHS advises that women at risk of gestational diabetes be given a screening test called an oral glucose tolerance test (OGTT) in the third and forth month of pregnancy.
