GESTATIONAL DIABETES

Gestational diabetes is hyperglycemia (increased blood glucose) that occurs during pregnancy which increases the risk of complications both during the antenatal period and at the time of delivery. Both mother and child are also at risk of developing type 2 diabetes in the future.

During pregnancy, certain maternal hormones make the pregnant woman more insulin resistant. This happens to all women to some degree, but women who are susceptible can develop gestational diabetes.

Risk factors for gestational diabetes include:

  • Family history of T2DM
  • Personal history of pre diabetes or previous gestational diabetes
  • Nonwhite race
  • Obesity

Women with a history of PCOS should be screened for diabetes after pregnancy because it is a risk factor for T2DM.
