Pregnant women get warning on diabetes
Women are being urged to maintain a healthy weight before and during pregnancy to prevent a "time bomb" of children developing diabetes in later life.
Research has shown that babies born to mothers who have gestational diabetes in pregnancy are six times more likely to develop Type 2 diabetes in later life.
Diabetes UK said women should keep to a healthy weight while trying to conceive and not gain too much weight in pregnancy to lower the risk of gestational diabetes.
Up to 18pc of pregnant women develop gestational diabetes, which is caused by too much glucose in the blood.
The condition usually disappears after the baby is born, but there are long-term health risks for mother and child.
Type 2 diabetes can lead to early death, heart disease, kidney failure and the need for amputation.
Gestational diabetes is also linked to premature birth, the need for a Caesarean section and high blood pressure in pregnancy.
"It is well established that gestational diabetes is a serious health issue that can cause birth defects, stillbirth and complications for the mother," said Diabetes UK chief executive Barbara Young.
