Gestational Diabetes Symptoms
Gestational diabetes mellitus (GDM) is a type of diabetes that develops during pregnancy. It often has no obvious symptoms, which is why universal screening with the glucose tolerance test is recommended at 24–28 weeks.
Common Causes
- Pregnancy hormones (especially human placental lactogen) cause insulin resistance
- The pancreas cannot produce enough extra insulin to overcome pregnancy-related insulin resistance
- Risk factors: overweight or obesity, family history of diabetes, prior gestational diabetes, polycystic ovary syndrome (PCOS), age over 35
Remedies That May Help
Blood Sugar Monitoring
Regular blood glucose testing (before and after meals) is the cornerstone of management.
Medical Nutrition Therapy
A registered dietitian creates a carbohydrate-controlled meal plan. Most women with GDM can control blood sugar with diet alone.
Regular Exercise
Walking 15–30 minutes after meals significantly lowers postprandial blood glucose.
Insulin or Oral Medications
If diet and exercise don't achieve target blood sugars, insulin (the safest choice in pregnancy) or metformin may be prescribed.
When to Call Your Doctor
- You have symptoms of high blood sugar: unusual thirst, frequent urination beyond normal pregnancy levels, blurred vision, or fatigue
- Blood glucose readings are consistently above targets
- You experience a low blood sugar episode (shakiness, dizziness, confusion) if you are on insulin
- Your baby seems to be growing very large (ultrasound findings)
Frequently Asked Questions
What are the symptoms of gestational diabetes?
Most women with GDM have no noticeable symptoms. In some cases, increased thirst, frequent urination, fatigue, or blurred vision may occur — but these also occur normally in pregnancy, making symptoms unreliable.
When is gestational diabetes screening done?
Universal screening is recommended between 24 and 28 weeks with a glucose challenge test (GCT) or oral glucose tolerance test (OGTT). High-risk women may be screened earlier.
Does gestational diabetes go away after birth?
Yes — blood sugars normalize for most women shortly after delivery. However, having GDM increases the lifetime risk of developing type 2 diabetes by 50%, so follow-up testing is recommended.
Can gestational diabetes harm my baby?
Uncontrolled GDM is associated with the baby growing too large (macrosomia), making delivery more difficult, and the baby having low blood sugar after birth. Well-controlled GDM significantly reduces these risks.
Can gestational diabetes be prevented?
Maintaining a healthy weight before pregnancy and following a balanced diet reduces risk. Exercise before and during pregnancy also has protective effects.
