Pregestational Diabetes

Pregestational diabetes is a serious condition that can have devastating health impacts on pregnant women and their unborn children. It occurs when the mother has high blood sugar levels before conceiving, which can lead to complications during pregnancy.

What is Pregestational Diabetes?

Pregestational diabetes, also known as gestational diabetes mellitus (GDM), is a type of diabetes that occurs during pregnancy. It affects how the body uses glucose, or sugar, and can cause high blood sugar levels in the mother. It is diagnosed when a woman’s glucose levels are higher than normal during her pregnancy.

Risk factors for GDM include being overweight or obese before becoming pregnant, having a family history of diabetes, and having previously had GDM or delivered a baby weighing more than nine pounds. Symptoms of pregestational diabetes may include increased thirst and urination, fatigue, nausea, and blurred vision. Treatment typically includes monitoring blood sugar levels closely and making dietary changes.

What are the different types of Pregestational Diabetes?

There are three main types of pregestational diabetes: Type 1, Type 2 and gestational diabetes.

Type 1 diabetes is an autoimmune disorder that requires insulin injections to keep blood sugar levels controlled.

Type 2 diabetes is a chronic condition where the body does not make enough insulin or does not use it effectively.

Gestational diabetes occurs during pregnancy when hormones from the placenta block the action of insulin. This can cause high blood sugar and must be monitored closely by a medical professional.

What causes Pregestational Diabetes?

Pregestational diabetes is caused by the body's inability to produce or use insulin properly. Insulin is a hormone produced in the pancreas that helps to regulate blood sugar levels. When the body does not produce enough insulin or cannot effectively use the insulin it produces, glucose accumulates in the bloodstream instead of being absorbed into cells for energy. This condition is known as pregestational diabetes and can be caused by genetic factors, lifestyle choices, and certain medical conditions.

What are the symptoms of Pregestational Diabetes?

Pregestational diabetes symptoms include increased thirst and urination, fatigue, weight loss, blurred vision, slow healing sores or cuts, itching or skin infections, yeast infections in women, and nausea. It is also possible to have no symptoms at all.

Blood tests are the only way to diagnose pregestational diabetes. If left undiagnosed or untreated, complications can arise for both mother and baby during pregnancy.

When should one see a doctor for Pregestational Diabetes?

Anyone who is pregnant and is experiencing any of the symptoms of pregestational diabetes—excessive thirst, frequent urination, increased blood glucose levels, or blurry vision—should see a doctor immediately.

Pregestational diabetes can cause serious complications during pregnancy, including miscarriage, birth defects, and stillbirth. Additionally, if you have a family history of diabetes, you should consult your doctor before trying to get pregnant. Early detection and treatment are key to helping reduce the risk of complications.

What are the risk factors for Pregestational Diabetes?

Pregestational diabetes is caused by having too much glucose (sugar) in the blood before pregnancy. Risk factors include being overweight or obese, being older than 25 years old, having a family history of diabetes, being of certain ethnic backgrounds (such as African American, Latino/Hispanic, Native American, Asian American, or Pacific Islander), having had gestational diabetes before, having polycystic ovary syndrome (PCOS), and having high blood pressure. Additionally, a sedentary lifestyle may increase the risk of developing pregestational diabetes.

How can one prevent Pregestational Diabetes?

Pregestational diabetes is associated with several risk factors, including advancing maternal age, obesity, a family history of diabetes, and a prior history of gestational diabetes. Women of certain ethnicities have an increased risk, such as African American, Hispanic/Latino American, Native American, Asian American Pacific Islander and South Asian. Those with high blood pressure or polycystic ovary syndrome (PCOS) are also at higher risk. Additionally, women who have had babies over nine pounds in the past may be more likely to develop pregestational diabetes.


Pregestational diabetes is a condition in which an expecting mother has high levels of blood sugar before becoming pregnant. It requires careful monitoring and treatment to ensure the health of both the mother and baby. With proper nutrition, lifestyle management, and medication, pregestational diabetes can be managed effectively.

The importance of timely diagnosis and successful management cannot be overstated; it is essential for the health of both mother and child. With support from healthcare professionals, women with pregestational diabetes can have healthy pregnancies and babies.
