What is diabetes in pregnancy?

Published in Pregnancy Diabetes 5 mins read

Diabetes in pregnancy refers to any form of diabetes that occurs or is first diagnosed during gestation. This primarily includes gestational diabetes, which develops during pregnancy, and pre-existing Type 1 or Type 2 diabetes managed throughout pregnancy. All types of diabetes in pregnancy affect how the body uses sugar (glucose), leading to high blood sugar levels that can impact both the pregnant individual's health and the baby's development.

Understanding Gestational Diabetes

Gestational diabetes is a type of diabetes that is diagnosed for the first time during pregnancy (gestation). Like other forms of diabetes, it affects how your cells use sugar (glucose), which is their primary source of energy. During pregnancy, hormonal changes can make the body's cells less responsive to insulin, a hormone responsible for moving glucose from the bloodstream into cells. When the pancreas cannot produce enough extra insulin to overcome this resistance, blood sugar levels rise, leading to gestational diabetes.

How Gestational Diabetes Affects the Body

Normally, after you eat, your pancreas releases insulin to help glucose enter your cells for energy. In gestational diabetes, this process is disrupted:

  • Insulin Resistance: Pregnancy hormones can make your cells more resistant to insulin.
  • Insufficient Insulin Production: Your pancreas may not be able to produce enough additional insulin to compensate for this resistance.
  • High Blood Sugar: As a result, glucose accumulates in your bloodstream instead of entering your cells, leading to high blood sugar.

This high blood sugar can then affect your pregnancy and your baby's health.

Types of Diabetes Encountered During Pregnancy

While gestational diabetes is specific to pregnancy, it's important to differentiate it from pre-existing diabetes types that women may have before conception.

Type of Diabetes Description Onset Typical Management During Pregnancy
Gestational Diabetes Diabetes diagnosed for the first time during pregnancy (gestation). It usually resolves after childbirth but increases the risk of developing Type 2 diabetes later in life. Develops during the second or third trimester. Diet changes, regular exercise, blood sugar monitoring; sometimes insulin or other medications.
Pre-existing Type 1 Diabetes An autoimmune condition where the body does not produce insulin. Present before pregnancy. Typically childhood or adolescence. Careful insulin management, frequent blood sugar monitoring, and close medical supervision.
Pre-existing Type 2 Diabetes A condition where the body doesn't use insulin well (insulin resistance) or can't produce enough insulin. Present before pregnancy. Often in adulthood, can occur at any age. Diet, exercise, oral medications, and/or insulin, with careful adjustments for pregnancy safety.

Why Diabetes in Pregnancy Matters: Potential Risks

Unmanaged high blood sugar during pregnancy, whether from gestational or pre-existing diabetes, can lead to various complications for both the pregnant individual and the baby.

Risks for the Baby

  • Macrosomia (Large Baby): Excess glucose crosses the placenta, causing the baby to store extra fat. This can lead to difficulties during birth, including shoulder dystocia (when the baby's shoulder gets stuck).
  • Hypoglycemia (Low Blood Sugar) at Birth: After birth, the baby's high insulin production continues, potentially leading to a sharp drop in blood sugar.
  • Breathing Problems: Babies may be born with immature lungs.
  • Increased Risk of Obesity and Type 2 Diabetes: Children born to mothers with diabetes in pregnancy have a higher likelihood of developing these conditions later in life.
  • Birth Defects: Specifically with pre-existing diabetes, uncontrolled blood sugar early in pregnancy increases the risk of birth defects affecting the brain, spine, or heart.

Risks for the Pregnant Individual

  • Preeclampsia: A serious pregnancy complication characterized by high blood pressure and signs of damage to another organ system, most often the kidneys and liver.
  • Increased Risk of C-section: Due to larger babies or other complications.
  • Future Diabetes Risk: Individuals with gestational diabetes have a significantly higher risk (up to 50%) of developing Type 2 diabetes later in life.
  • Polyhydramnios: Too much amniotic fluid.

Managing Diabetes in Pregnancy

Effective management is crucial to minimize risks and ensure a healthy pregnancy outcome.

Key Strategies Include:

  1. Dietary Modifications:
    • Focus on complex carbohydrates, lean proteins, and healthy fats.
    • Limit sugary foods, refined grains, and processed snacks.
    • Consider working with a registered dietitian for a personalized meal plan.
  2. Regular Physical Activity:
    • Aim for moderate exercise, such as brisk walking, for at least 30 minutes most days of the week, with your doctor's approval.
    • Exercise helps lower blood sugar by increasing insulin sensitivity.
  3. Blood Glucose Monitoring:
    • Regularly check blood sugar levels at home using a glucometer, typically multiple times a day (before and after meals, and at bedtime).
    • This helps track how diet and activity affect blood sugar and guides treatment adjustments.
  4. Medication (If Needed):
    • If diet and exercise aren't enough to manage blood sugar, your healthcare provider may prescribe insulin injections or oral medications like metformin, which are safe for use during pregnancy.
  5. Close Medical Supervision:
    • Frequent prenatal appointments allow your healthcare team to monitor blood sugar, baby's growth, and overall health.
    • Learn more about managing diabetes during pregnancy from reputable sources like the American Diabetes Association.

Practical Tips for Daily Management

  • Plan Your Meals: Prepare meals in advance to avoid unhealthy choices.
  • Stay Hydrated: Drink plenty of water throughout the day.
  • Read Food Labels: Pay attention to carbohydrate content and serving sizes.
  • Carry Healthy Snacks: Keep blood sugar steady between meals.
  • Communicate with Your Healthcare Team: Report any concerning symptoms or difficulties in managing your blood sugar.

For most individuals, gestational diabetes resolves after the baby is born. However, follow-up testing and lifestyle adjustments are essential to reduce the long-term risk of developing Type 2 diabetes.
