Doctors don’t know why some women develop gestational diabetes, but they do know how it happens. During pregnancy, the placenta, which connects the blood supply of a mother to that of the baby, produces high levels of various hormones. As the baby grows, the placenta starts producing more and more hormones. In gestational diabetes, these hormones provoke an elevation in blood sugar to the point that it negatively affects the health of the mother and the child. Other risk factors include:
- Age: Women greater than 25 have a greater chance of developing gestational diabetes.
- Family history: The risk increases if someone in your family has or has had diabetes, also if you have pre-diabetes.
- Excess Weight: Overweight people have a higher chance of developing gestational diabetes.
- Race: Non-white woman like those who are Black, Hispanic, American-Indian or Asian have a higher chance of developing this condition.
