🩸 Insulin Resistance and the Hidden Balance Behind Normal Blood Sugar

The simulator demonstrates the dynamic push-and-pull between tissue insulin sensitivity and beta cell insulin output, showing how their opposing changes keep blood glucose stable for a period of time, how HOMA-IR reveals the hidden strain in that balance, and how blood glucose finally rises once beta cell compensation can no longer keep up with worsening resistance.

🔬 What It Demonstrates

The simulator demonstrates the dynamic push-and-pull between tissue insulin sensitivity and beta cell insulin output, showing how their opposing changes keep blood glucose stable for a period of time, how HOMA-IR reveals the hidden strain in that balance, and how blood glucose finally rises once beta cell compensation can no longer keep up with worsening resistance.

🎮 How to Use

Adjust the tissue insulin sensitivity slider downward to simulate worsening insulin resistance, and watch the beta cell output rise automatically to compensate while blood glucose stays flat. Then reduce the beta cell secretory capacity slider to simulate beta cell fatigue and observe how blood glucose and HOMA-IR respond once compensation can no longer keep pace, tracking the shift from normal through prediabetes toward diabetic range.

💡 Did You Know?

Did you know that by the time fasting glucose crosses into the prediabetic range, tissue insulin sensitivity has often already been declining for many years, quietly hidden behind rising insulin output that a standard glucose-only blood test would never reveal?
