Treatment Overview
Gestational Diabetes Two-Step Screening & Management Algorithm in Korea is a pregnancy-specific form of glucose intolerance caused by hormonal changes that interfere with insulin regulation. Early detection and timely management are critical to prevent complications for both mother and baby.
In Korea, most hospitals and maternal-fetal medicine centers follow the Two-Step Screening and Management Algorithm — a structured, evidence-based approach that ensures accurate diagnosis, efficient intervention, and personalized glucose control.
This model includes an initial glucose challenge screening followed by a confirmatory oral glucose tolerance test (OGTT), along with individualized care pathways that combine nutrition, exercise, monitoring, and insulin therapy when required. Korea’s precise, algorithmic approach is globally regarded for its effectiveness in managing GDM while maintaining maternal and fetal safety.
Purpose & Benefits
Purpose:
- To provide a standardized, accurate method for diagnosing and managing gestational diabetes.
- To ensure early identification of women with glucose intolerance during pregnancy.
- To guide stepwise treatment according to severity and individual glucose patterns.
- To prevent pregnancy complications by maintaining optimal maternal blood sugar levels.
- To promote consistent national protocols for high-quality prenatal care.
Benefits:
- Accurate diagnosis: Reduces false positives and ensures reliable risk categorization.
- Stepwise intervention: Avoids unnecessary medication through progressive management.
- Improved maternal outcomes: Lowers the incidence of hypertension, preeclampsia, and cesarean section.
- Better fetal outcomes: Minimizes risks of macrosomia, hypoglycemia, and preterm birth.
- Evidence-based care: Supported by robust Korean clinical guidelines and population data.
- Cost-effectiveness: Targets only those truly at risk, optimizing hospital resources and patient safety.
Ideal Candidates
The two-step screening and management algorithm applies to:
- All pregnant women, typically between 24–28 weeks of gestation.
- High-risk women requiring earlier testing, including those with:
- Family history of diabetes.
- Obesity or excessive weight gain.
- Advanced maternal age (≥35 years).
- Previous gestational diabetes or large baby (>4 kg).
- Polycystic ovary syndrome (PCOS) or metabolic syndrome.
- Hypertension or thyroid disorders.
Korean hospitals often perform risk stratification during the first trimester and initiate early screening for at-risk patients.
Possible Risks & Considerations
- Mild discomfort during blood draws or glucose ingestion.
- False negatives if dietary or physiological variations affect results.
- Emotional anxiety due to repeated testing; addressed through prenatal counseling.
- Need for follow-up: Even after normal results, re-testing may be needed if risk factors persist.
Korea’s structured care system minimizes these risks through clear patient education and advanced laboratory precision.
Medical & Diagnostic Techniques Used in Korea
Korean hospitals follow internationally recognized GDM diagnostic standards while incorporating local population data and technology for enhanced accuracy.
Step 1: Initial Glucose Challenge Test (GCT)
- Conducted between 24–28 weeks of gestation.
- The patient consumes a 50-gram glucose solution, and plasma glucose is measured after one hour.
- Threshold for further testing: Typically ≥140 mg/dL (some centers use ≥130 mg/dL for higher sensitivity).
- This step is performed without fasting, making it simple and widely applicable.
Step 2: Oral Glucose Tolerance Test (OGTT)
- Conducted if Step 1 result is abnormal.
- The patient fasts overnight, then consumes 100 grams of glucose solution.
- Blood glucose levels are measured at fasting, 1-hour, 2-hour, and 3-hour intervals.
- GDM is diagnosed if two or more values exceed the reference thresholds (Carpenter–Coustan or NDDG criteria).
Additional Techniques and Tools:
- Digital data collection: Test results automatically integrate into patient electronic medical records (EMRs).
- AI-based diagnostic interpretation: Korean hospitals use algorithms to flag borderline or inconsistent results.
- Continuous glucose monitoring (CGM): For high-risk or confirmed GDM patients, real-time glucose trends guide management.
- Population-specific glucose reference tables: Adjusted for Korean maternal physiology to ensure precision.
This two-step diagnostic pathway forms the foundation of Korea’s gestational diabetes management system, balancing accuracy, safety, and accessibility.
Recovery & Aftercare
- Immediate counseling: Patients receive education after diagnosis regarding diet and lifestyle modifications.
- Follow-up assessments: Regular glucose monitoring at home or via telehealth apps.
- Nutritional therapy: Balanced meal planning customized by trimester and glucose response.
- Physical activity programs: Safe, low-impact exercises to improve insulin sensitivity.
- Medication management: If glucose remains uncontrolled, insulin therapy or oral medication is introduced under supervision.
- Postpartum follow-up: 6–12 weeks after delivery, mothers undergo glucose tolerance testing to detect lingering metabolic changes.
Korean hospitals maintain coordinated, long-term care systems linking endocrinology, obstetrics, and nutrition to ensure stable glucose management and healthy recovery.
Results & Longevity
- High detection accuracy: Over 95% of GDM cases are identified using the two-step system.
- Effective glucose control: Timely diagnosis reduces maternal complications and fetal morbidity.
- Reduced need for insulin: Most women manage successfully with diet and exercise.
- Improved birth outcomes: Lower rates of preeclampsia, cesarean section, and neonatal hypoglycemia.
- Sustained prevention: Early education leads to better postpartum glucose maintenance and lifelong health awareness.
- Global recognition: Korea’s protocol aligns with top-tier maternal health standards worldwide.
The two-step approach ensures both precision and continuity, contributing to excellent outcomes for mothers and infants.
Procedure Process in Korea
1. First Prenatal Visit – Risk Evaluation
All expectant mothers are screened for GDM risk factors during early pregnancy. Those at high risk undergo early glucose testing.
2. Standard Two-Step Screening
At 24–28 weeks, the first 50-gram glucose challenge test is performed. If the result exceeds threshold levels, a confirmatory OGTT is scheduled.
3. Diagnosis & Classification
Patients are classified as normal, borderline, or gestational diabetes positive. Each classification determines the next level of management.
4. Management Algorithm Implementation
- Mild cases: Lifestyle and dietary modification.
- Moderate cases: Nutrition therapy + glucose monitoring.
- Severe/uncontrolled cases: Addition of insulin therapy and frequent fetal monitoring.
5. Continuous Glucose & Fetal Surveillance
CGM, Doppler ultrasounds, and growth scans monitor maternal and fetal well-being throughout pregnancy.
6. Postpartum Care & Education
After delivery, glucose testing confirms remission. Mothers receive counseling on postpartum diet, weight control, and future diabetes prevention.
