Prediabetes & Insulin Resistance

 

What is Insulin Resistance?

Insulin resistance occurs when cells in your muscle, fat, and liver do not respond effectively to insulin—the hormone produced by the pancreas that allows glucose (sugar) in your blood to enter cells for energy.

To overcome this resistance and keep blood sugar stable, the pancreas overproduces insulin (hyperinsulinemia). Over time, the pancreas can no longer keep up with the high demand.

​

What is Prediabetes?

Prediabetes is the metabolic state where blood sugar levels are higher than normal, but not yet high enough to be classified as Type 2 diabetes. It is the direct consequence of long-term, unmanaged insulin resistance.

​

​Symptoms & Early Warning Signs

Insulin resistance and prediabetes are often called "silent conditions" because they frequently develop without prominent symptoms. However, subtle physical indicators may be present:

• Acanthosis Nigricans: Darkened, velvety skin patches, most commonly found on the back of the neck, armpits, or groin.

• Skin Tags: Small, benign skin growths in body creases.

• Abdominal Obesity: Centralized weight accumulation around the waist line line.

• Persistent Fatigue: Feeling tired or sluggish, especially after carbohydrate-heavy meals.

• Intense Sugar Cravings: Constant cravings for simple carbohydrates or sweets due to impaired cellular glucose absorption.

​

Diagnostic Criteria & Testing

• HbA1c (3-Month Average Blood Sugar):

  • Prediabetes Range: 5.7% to 6.4%

  • Normal Range: Below 5.7%

• Fasting Blood Glucose (FBG):

  • Prediabetes Range: 100 to 125 mg/dL

  • Normal Range: 70 to 99 mg/dL

• Oral Glucose Tolerance Test (OGTT - 2-Hour Post Glucose):

  • Prediabetes Range: 140 to 199 mg/dL

  • Normal Range: Below 140 mg/dL

• Fasting Serum Insulin & HOMA-IR:

  • Prediabetes / Insulin Resistance: Evaluates hyperinsulinemia and calculates the insulin resistance index

  • Normal Baseline: Fits within standard age- and gender-adjusted laboratory baselines

​

Medical Management & Treatment Plan

The progression from prediabetes to Type 2 diabetes is not inevitable. With structured, evidence-based care, insulin resistance can be managed and prediabetes reversed.

• Personalized Nutrition

• Structured Physical Activity

• Medical Interventions & Pharmacotherapy

​

Long-Term Care & Prevention Strategy

Continuous monitoring under specialized endocrine care ensures sustained health outcomes:

• Regular Monitoring: HbA1c and lipid profiling every 3 to 6 months.

• Screening for Associated Conditions: Monitoring for PCOS, fatty liver disease (MASLD/NAFLD), and hypertension.

• Targeted Weight Reduction: Achieving and maintaining even a 5% to 10% weight loss significantly improves insulin sensitivity.
