Gestational Diabetes
High blood sugar that develops during pregnancy, usually diagnosed between 24-28 weeks.
Affects: Affects 2-10% of pregnancies in the US
Overview
Gestational diabetes occurs when your body cannot produce enough insulin during pregnancy to keep blood sugar at healthy levels. Pregnancy hormones make your cells more resistant to insulin, and some women's bodies can't keep up with the increased insulin demand.
Most women with gestational diabetes have healthy pregnancies and babies with proper management. The condition usually resolves after delivery, though it increases risk of developing type 2 diabetes later in life.
Management involves monitoring blood sugar levels, eating a balanced diet, exercising regularly, and sometimes medication. With treatment, most women deliver healthy babies at term.
🩺 Symptoms
- •Often no obvious symptoms
- •Increased thirst
- •Frequent urination (more than typical for pregnancy)
- •Fatigue beyond normal pregnancy tiredness
- •Sugar in urine (detected at prenatal visits)
- •Diagnosed through glucose tolerance test
🔍 Causes
- →Pregnancy hormones blocking insulin action (insulin resistance)
- →Pancreas unable to produce enough extra insulin
- →Pre-existing insulin resistance
- →Weight gain during pregnancy
- →Placental hormones affecting insulin
⚠️ Risk Factors
- •Overweight or obese before pregnancy (BMI over 30)
- •Age over 25
- •Family history of diabetes
- •Previous gestational diabetes
- •Previous baby over 9 pounds
- •PCOS (polycystic ovary syndrome)
- •Prediabetes
- •African American, Hispanic, Asian, Native American ethnicity
- •Physically inactive
🔬 Diagnosis
- →Glucose challenge test at 24-28 weeks (standard screening)
- →One-hour test with 50g glucose drink
- →If screening positive: three-hour glucose tolerance test
- →Fasting blood sugar, then glucose drink, blood drawn at 1, 2, 3 hours
- →Diagnosed if 2 or more values elevated
- →Some women tested earlier if high risk
💊 Treatment
- ✓Monitor blood sugar 4 times daily (fasting and after meals)
- ✓Follow diabetic diet - control carbohydrates
- ✓Regular exercise (walking 30 minutes daily)
- ✓Count carbohydrates and spread throughout day
- ✓Avoid refined sugars and simple carbs
- ✓Medication if diet/exercise insufficient (metformin or insulin)
- ✓More frequent prenatal visits and ultrasounds
- ✓Fetal monitoring in third trimester
- ✓Possible induction at 39-40 weeks
🛡️ Prevention
- →Maintain healthy weight before pregnancy
- →Lose excess weight before conceiving
- →Exercise regularly before and during pregnancy
- →Eat balanced diet low in refined carbohydrates
- →Gain recommended pregnancy weight (not excessive)
- →If previous GDM, early screening and lifestyle changes

- !Increased C-section risk
- !Baby's low blood sugar at birth (hypoglycemia)
- !Preterm birth
- !Preeclampsia
- !Polyhydramnios (too much amniotic fluid)
- !Stillbirth (rare with good control)
- !Future type 2 diabetes risk for mother (50% develop within 10 years)
- !Baby's increased obesity and diabetes risk later in life
