Gestational diabetes is a type of diabetes that affects women during pregnancy. About 10% of pregnancies in the United States are impacted by gestational diabetes every year. However, there are ways to treat this condition without it severely affecting your or your child.
In this article, we will discuss everything around gestational diabetes, including causes, symptoms, and how it may affect both you and your child. Here is a basic summary before getting into more detail.
Gestational Diabetes: The exact cause of gestational diabetes is not fully known. However, the hormones in the placenta may cause the insulin of the mother not to work as effectively. This results in insulin resistance. Women carrying excess weight before pregnancy may also have a role in causing gestational diabetes.
Now that you have a basic understanding of this condition, here is everything that you should know.
Gestational diabetes mellitus is a type of diabetes that is diagnosed during the second and third trimester. This is not a form of type 1 or type 2 diabetes. Therefore, pregnant women are recommended to get tested for diabetes during the first trimester to rule out the potential of a preexisting condition.
Evidence suggests that gestational diabetes has been becoming more and more common in the United States. It is believed that this coincides with the increasing rates of obesity in the United States.
A woman’s body goes through many changes during pregnancy, including hormonal changes. This is thought to be one of the main causes of gestational diabetes.
It is natural for a pregnant woman’s body to become slightly resistant to insulin. This is to allow more nutrients to be supplied to the fetus. In response, the body will start to produce more insulin. However, some women may have insufficient insulin levels or too much resistance to insulin, leading to uncontrolled blood sugar levels.
Women that are overweight heading into a pregnancy may be more likely to develop gestational diabetes. This is because excess weight, especially around the midsection, can increase a person’s risk of developing insulin resistance.
Lifestyle factors may increase your risk of developing gestational diabetes. This may include the type of foods one is eating the amount of exercise one is getting. Exercise can improve a person’s insulin sensitivity and help reduce blood sugar levels. Maintaining a healthy diet can also reduce one’s likelihood of developing insulin resistance.
Overview of Gestational Diabetes

How is Gestational Diabetes Diagnosed
The American Diabetes Association recommends that all pregnant women without type 1 or type 2 diabetes should be screened for gestational diabetes between 24-28 weeks. One screening process for gestational diabetes includes an oral glucose test. This means that the patient fasts for 8 hours before receiving a glucose drink to be consumed. The blood glucose levels are measured before administering the glucose drink and at one and two hours after administering the glucose. If blood glucose levels exceed the threshold measurements, then gestational diabetes may be diagnosed. The threshold levels are as follows:- Fasting: 92 mg/dL
- After 1 hour: 180 mg/dL
- After 2 hours: 153 mg/dL
Symptoms and Warning Signs
Signs and symptoms of gestational diabetes include:- Unusual thirst or dry mouth
- Frequent urination
- Fatigue
- Nausea
- Frequent infections
- Blurry vision
- Tingling of hands and feet
Causes and Risk Factors
Gestational diabetes is caused mostly by changes in hormones during pregnancy, resulting in insulin resistance. This means there may be an imbalance of insulin and other hormones that can trigger a glucose response. Hormones that can be more prevalent in pregnant women and can trigger a glucose response include:- Cortisol
- Growth hormones
- Adrenaline
- Estrogen
- Progesterone
- Human placental lactogen
- Placental insulinase
