About Gestational Diabetes

What is Gestational Diabetes?
Gestational Diabetes is characterized as a high blood sugar level that appears during pregnancy and usually disappears after pregnancy. It usually appears around the 24th week of pregnancy when the placenta begins producing large quantities of hormones that cause insulin resistance.

  • Ketones are substances that the body produces when it breaks down fat for energy. They cross the placenta and enter the baby’s blood stream. This may happen when your diet is low in carbohydrates or if your body cannot use glucose properly.
  • You will need to check your urine every morning during pregnancy for the presence of ketones.
  • Treatment
  • Do not skip meals or decrease calories. East three meals/three snacks per day as outlined by your dietician. If you have moderate or large amounts of ketones for two mornings in a row call your Diabetes Nurse Educator or Dietician – you probably need more calories
  • Blood Glucose Testing
  • Fasting: A blood sugar between 95 - 100 mg/dl.
  • If you are on insulin the fasting blood sugar should be between 85 - 92 mg/dl.
  • 1 hour after finishing a meal: A blood sugar of less than 130 mg/dl. Check your blood sugar when fasting and 1 hour after every meal. Call your Doctor or Diabetes Nurse Educator if your blood sugar is above 100 in the morning or above 130 one hour after meals for two (2) days in a row. Evaluation by the endocrinologist may be required to see if insulin is needed.
