The study found that having two parents with diabetes increased a woman's likelihood of having diabetes eightfold but only doubled the likelihood of gestational diabetes. When a woman has a diabetic sibling, there was a sevenfold increase in the risk of gestational diabetes but only a slightly elevated risk of Type 2 diabetes. The results were based on a study of 4,566 mothers who participated in the National Health and Nutritional Examination Survey.Source
At a time when even children are being diagnosed with diabetes, this is especially helpful for women of child-bearing age. Hopefully, people from families with a diabetic history will be more vigilant with their diet and lifestyle and will get themselves tested regulalry. And pregnant women from such families would do well to follow a strict diet and lifestyle plan during their pregnancy to avoid gestational diabetes, which brings about so many pregnancy and birth complications.
