Among women with diabetes who become pregnant, the majority will have type 1
diabetes, although some aged 30 plus will have type 2 diabetes.
Any pregnant woman with known diabetes requires specialist care and advice.
Pre-pregnancy care
Women with type 1 diabetes have a slightly increased risk of having a baby
with a birth defect. Excellent control at the time of conception and during the
first eight weeks of pregnancy minimises this risk.
It is therefore extremely important to plan the pregnancy and achieve the
best possible blood glucose control before becoming pregnant.
Women with type 2 diabetes who are planning a pregnancy ideally should cease
taking tablets and achieve excellent diabetes control on insulin before
conception.
Careful attention to nutrition is essential, not only for good diabetes
control, but to meet the bodys increased nutritional requirements during
pregnancy.
Exercise is also helpful in maintaining general fitness and good blood
glucose control.
Breast-feeding
There is no reason why women with diabetes should not breast-feed. Insulin
requirements are generally slightly lower in the breast-feeding mother so take
particular care to avoid hypoglycaemia. Insulin does not pass into the breast
milk and is not harmful to the baby.
However, oral hypoglycaemic tablets are passed into breast milk, and women on
tablets before pregnancy should continue on insulin treatment while
breast-feeding.
