  • Without intervention, 70% will develop type 2 diabetes within 10 years
  • Only 20% of people with prediabetes know they have it
  • Lifestyle changes can reduce diabetes risk by up to 58%

What Causes Prediabetes?

Understanding the underlying causes helps in prevention and management:

Primary Risk Factors:

  1. Genetic Predisposition
  • Family history of diabetes
  • Certain ethnic backgrounds (African American, Hispanic, Native American)
  • Age over 45
  1. Lifestyle Factors

  • Poor diet high in processed foods
  • Smoking
  • Chronic stress
  1. Medical Conditions
  • Polycystic ovary syndrome (PCOS)
  • Gestational diabetes history

Comprehensive Diagnostic Testing

Standard Blood Tests

  1. Fasting Blood Sugar (FBS)
  • Normal: < 100 mg/dL
  • Prediabetes: 100-125 mg/dL
  • Diabetes: ≥ 126 mg/dL
  • Test requires 8-hour fast
  1. Hemoglobin A1C (HbA1c)
  • Normal: < 5.7%
  • Prediabetes: 5.7%-6.4%
  • Diabetes: ≥ 6.5%
  • Reflects 2-3 month average
  1. Oral Glucose Tolerance Test (OGTT)
  • Normal: < 140 mg/dL
  • Prediabetes: 140-199 mg/dL
  • Diabetes: ≥ 200 mg/dL
  • Measures response to glucose load

Additional Health Markers

  • Insulin levels
  • Lipid panel
  • Blood pressure
  • Waist circumference

Early Warning Signs and Symptoms

While prediabetes often develops silently, watch for these indicators:

Common Symptoms:

  • Increased thirst

Less Common Signs:

  • Mood changes
  • Increased hunger
  • Weight changes despite normal eating
  • Numbness or tingling in extremities

Long-term Health Implications

Prediabetes affects multiple body systems:

Cardiovascular System

  • 50% higher risk of heart disease
  • Increased stroke risk
  • Higher blood pressure

Metabolic Health

  • Insulin resistance
  • Metabolic syndrome
  • Weight management issues

Other Systems

  • Nerve damage (neuropathy)
  • Kidney dysfunction
  • Vision problems
  • Cognitive decline risk

Evidence-Based Management Strategies
