Diabetes in Pregnancy Consultation

Diabetes often begins long before pregnancy, and other times, it results from the body reacting to being pregnant (called gestational diabetes mellitus). As Los Angeles’s preeminent high-risk pregnancy specialist, Dr. Steve Rad is an expert on overseeing the potential complications of diabetes during pregnancy.

Poor control of diabetes during pregnancy increases the risk of congenital disabilities and other risk factors for the expectant mother.

Diabetes During Pregnancy

What is diabetes?

Diabetes is a condition where the body cannot use the sugars and starches it takes in as food to make energy. The body produces too little or no insulin and cannot use it to change blood glucose into energy. As a result, extra sugar builds up in the blood (hyperglycemia) which can be harmful to the body.

Some ethnicities are at higher risk of developing diabetes. These include African Americans, Hispanic/Latino Americans, Asian Americans, Indigenous peoples, and Pacific Islanders.

Patients with a family history of diabetes are at higher risk of developing gestational diabetes – if they don’t already have diabetes.

There are three types of diabetes: type 1, type 2, and gestational diabetes.

What is type 1 diabetes?

Type 1 diabetes is suspected to be an autoimmune reaction that destroys the cells in the pancreas that make insulin. This dynamic can go on for years before any symptoms appear. Though the disease is not preventable, it can be managed with glucose monitoring and injected insulin.

Women with type 1 diabetes are able to have a normal, healthy pregnancy. However, it is imperative they control their blood sugar levels. Before becoming pregnant, discuss a strategy with your health care provider and be sure to attend all follow-up appointments.

Work with your doctor to keep your A1C levels (the amount of insulin sticking to red blood cells) as low as possible. Though the A1C measurement is most accurately found during bloodwork, it is possible to estimate your A1C at home using an estimated Average Glucose (eAG) level chart. Be aware that your need for insulin may change during pregnancy; consider using a continuous glucose monitor.

Without proper blood sugar control during pregnancy, severe complications may occur.

What is type 2 diabetes?

Type 2 diabetes is when the pancreas makes sufficient insulin, but the cells don’t respond. Also called insulin resistance, the pancreas keeps pushing insulin into the bloodstream, but because cells cannot assimilate insulin, blood sugar still rises. Chronic high blood sugar can cause disastrous side effects such as heart disease, loss of vision, and kidney problems.

The key to a healthy pregnancy with type 2 diabetes is planning with a maternal-fetal medicine specialist before conceiving. The doctor will check your weight, medication, and diet to help stabilize glucose levels and maintain them.

Depending on your overall health, the doctor may suggest holding off on having a child until your condition is more under control. The doctor may also suggest blood sugar control during pregnancy, often a more strict regimen.

What is gestational diabetes mellitus?

Gestational diabetes occurs when the body is overburdened by pregnancy, and the pancreas does not produce an adequate insulin supply. At the same time, cells become insulin resistant, and high blood sugar readings may follow.

There is some degree of insulin resistance in all pregnant people during the third trimester. Women who begin pregnancy with some insulin resistance have an increased risk for gestational diabetes. Patients with gestational diabetes are at a higher risk of developing Type 2 diabetes.

Gestational glucose tolerance occurs in pregnant people who have never experienced problems with their blood sugar. Some women experience this disease with every pregnancy, others only once. Occasionally, patients struggle with beginning breastfeeding after gestational diabetes.

Some studies suggest the higher prevalence of gestational diabetes is related to maternal obesity.

When do they test for diabetes in pregnancy?

Doctors typically test for gestational diabetes between 24 and 28 weeks of gestation. While sometimes patients will have to take insulin, gestational diabetes can also be controlled with a healthy diet, exercise, and other lifestyle changes.

What are the risks of diabetes in pregnancy?

High blood sugar readings are not good for the mother or baby. Without proper blood sugar control during pregnancy, severe complications may occur. These include:

Fetal macrosomia

Fetal macrosomia is a baby born larger than average. These babies’ weight is more than 8 pounds, 13 ounces at birth. Only about 9% of babies worldwide weigh this much. Risks increase if the baby weighs more than 9 pounds, 15 ounces.

This condition may make a vaginal delivery difficult or even impossible. Fetal macrosomia also increases the baby’s risk of health problems after birth.


Cesarean sections are much more prevalent in diabetic mothers. Because the baby is delivered through incisions in the abdomen and uterus, it takes longer for the mother to recover from birth.


Preeclampsia occurs only in pregnant patients. Typical symptoms include hypertension, a trace amount of protein in the urine, and swelling (edema) in the fingers and toes.

High blood pressure may harm the baby, and patients with diabetes are more prone to high blood pressure. Preeclampsia can cause the baby to be born preterm and with low birth weight and cause a seizure or stroke in the mother during delivery.


Low blood sugar can occur in patients who take insulin or diabetes medications. Low blood sugar is an acute disease and can be fatal if not addressed immediately.

This condition can be avoided by keeping blood sugar under control. If the expectant mother does develop hypoglycemia, the baby must be monitored for low blood sugar immediately after delivery.

Ideal “diabetes in pregnancy” diet

Eating a proper diet for diabetic pregnant women can be the key to a healthy delivery.

Dr. Rad will assist you in constructing the proper diet during diabetic pregnancy. However, there are several basic diet rules to follow:

  • Eat plenty of fruits and vegetables
  • Moderate amounts of proteins and healthy fats
  • Whole grains, such as bread, cereal, pasta, rice, and starchy vegetables
  • Reduce intake of foods with high sugar, such as soft drinks, fruit juices, and pastries

What causes diabetes in pregnancy?

Diabetes in pregnancy, known as gestational diabetes, is primarily caused by hormonal changes. As the placenta grows, it produces hormones that can interfere with the body’s ability to use insulin effectively, leading to insulin resistance. This means that the body may need more insulin. If the pancreas cannot produce enough insulin to compensate for this increased demand, gestational diabetes can develop.

How common is diabetes in pregnancy?

Diabetes in pregnancy, also known as gestational diabetes, is relatively common, affecting approximately 6-9% of pregnant women in the United States. The prevalence may vary depending on factors such as ethnicity, age, and preexisting health conditions. Women who are overweight or obese, have a family history of diabetes, or have previously experienced gestational diabetes are at higher risk of developing the condition.

What are the symptoms of diabetes in pregnancy?

Diabetes in pregnancy, also known as gestational diabetes, often does not present with noticeable symptoms. However, some women may experience symptoms such as increased thirst, frequent urination, fatigue, blurred vision, and increased hunger.

Can eating too much sugar cause diabetes in pregnancy?

Eating too much sugar alone does not directly cause gestational diabetes in pregnancy. However, excessive sugar consumption can contribute to weight gain and increase the risk of developing gestational diabetes, especially in women who are already predisposed to the condition. Therefore, maintaining a balanced diet low in added sugars and high in nutritious foods, along with regular exercise, is important for reducing the risk of gestational diabetes.

Will I have gestational diabetes in my second pregnancy

While having gestational diabetes in a previous pregnancy does increase the risk of developing it again, it’s not a certainty. Factors such as age, weight,

family history of diabetes, and overall health can also influence your risk. Maintaining a healthy lifestyle, including regular exercise and a balanced diet, can help reduce the risk of gestational diabetes in subsequent pregnancies.

Does diabetes in pregnancy go away?

Gestational diabetes is a temporary condition that affects some women during their pregnancy. Most women see their blood sugar levels return to normal within a few hours or days after giving birth.

Does gestational diabetes get worse later in pregnancy?

Gestational diabetes does not necessarily get worse as the pregnancy progresses, but it does require careful monitoring and management throughout the entire pregnancy.
