Insulin is often required when the initial fasting plasma glucose is greater than 250 mg/dL or the HbA1c is greater than 10%.
Here’s a breakdown:
- Fasting Plasma Glucose: If a blood test taken after fasting shows a glucose level consistently above 250 mg/dL, insulin therapy is often considered.
- HbA1c: This test reflects your average blood sugar level over the past 2-3 months. An HbA1c above 10% typically indicates a need for insulin to manage blood sugar effectively.
| Measurement | Level Requiring Consideration of Insulin |
|---|---|
| Fasting Plasma Glucose | Greater than 250 mg/dL |
| HbA1c | Greater than 10% |
