Risk Factors for Gestational Diabetes
by Mary Calvagna, MS
It is possible to develop gestational diabetes with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing gestational diabetes. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.
Risk factors for gestational diabetes include:
Obesity or Overweight
Studies found that women with a body mass index (BMI) of 25.0 to 29.9 (classified as overweight) are at an increased risk of gestational diabetes. If your BMI is over 30, you are at an even greater risk.
Gestational Diabetes in a Previous Pregnancy
If you had gestational diabetes with a previous pregnancy, this puts you at risk for developing the condition again.
Being older than 35 may increase your risk of gestational diabetes.
Family History of Diabetes
If you have a first-degree relative (parents, siblings) with diabetes, your risk of gestational diabetes is increased.
You may be at an increased risk of developing gestational diabetes if you are:
Previous Delivery of a Large Baby
If you delivered a baby who was excessively large at birth (called macrosomia), this increases your chance of gestational diabetes in your next pregnancy.
