Diabetes During Pregnancy: Setting Blood Sugar Targets, Testing Methods, and Further Information

Gestational diabetes is a type of diabetes that develops during pregnancy. This condition, if left unmanaged, can cause a range of problems for both the mother and the baby.

Risks for the Mother

If gestational diabetes goes untreated, it can lead to pregnancy and delivery complications such as preeclampsia, labor induction or a cesarean section, and perineal trauma. In some cases, it may necessitate more frequent doctor's appointments than usual.

Risks for the Baby

Babies born to mothers with uncontrolled gestational diabetes can face issues like low blood sugar, breathing problems, and an increased risk of obesity later in life.

Testing and Treatment

Testing blood glucose levels is a crucial part of managing gestational diabetes. A person can check their blood sugar levels at any time with blood glucose testing, and there are various types of glucose monitors available, most of which are relatively easy to use. People with gestational diabetes can test their blood sugar levels at home using a blood glucose monitor.

The first line of treatment for gestational diabetes is a combination of diet and exercise. The American Diabetes Association (ADA) suggests the Diabetes Plate Method as a way to put together nutritious meals without measuring or weighing food or counting calories. A doctor may also advise adjustments to the diet and may refer a person to a dietitian.

Exercise is critical for people with gestational diabetes, and doctors often prescribe physical activity.

Medication

In some cases, medication may be necessary to manage gestational diabetes. Injected insulin does not cross the placenta and does not affect a developing fetus. However, Metformin, a medication often used to treat type 2 diabetes, crosses the placenta and can potentially affect fetal development. While Metformin does not have FDA approval for treating diabetes during pregnancy, a doctor might prescribe it off-label if the benefits outweigh the risks.

Monitoring and Goals

The ADA recommends specific blood sugar goals for individuals with gestational diabetes to optimize maternal and fetal outcomes. These targets generally include:

Fasting blood glucose less than or equal to 95 mg/dL (5.3 mmol/L)
One hour after meals less than or equal to 140 mg/dL (7.8 mmol/L)
Two hours after meals less than or equal to 120 mg/dL (6.7 mmol/L)

These targets are set to balance glycemic control without causing hypoglycemia, which in pregnancy is defined as blood glucose below 70 mg/dL (3.9 mmol/L).

Continuous glucose monitoring (CGM) has been increasingly used in gestational diabetes to closely monitor these glucose parameters and improve outcomes.

Symptoms and Precautions

If you are experiencing possible gestational diabetes symptoms such as frequent urination, fatigue, or nausea, it's important to contact a doctor. Pregnant individuals should also seek immediate medical attention if they experience increased nausea and vomiting, regular contractions, fluid leakage, vaginal bleeding, or decreased or absent fetal movement.

Post-Pregnancy

Most pregnant individuals' blood sugar levels come down after they give birth, but some people with gestational diabetes develop type 2 diabetes later in life. It's essential to maintain a healthy lifestyle to reduce this risk.

The ADA provides a free printable log sheet, and there are several smartphone apps to track blood glucose levels. It's a good idea for a person to record their results to share with a doctor and to take notes on what might have affected their blood sugar levels.
