1. What is HOMA-IR?

HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) is a method used to quantify insulin resistance and beta-cell function. It's calculated from fasting blood glucose and insulin levels.

2. How Does the Calculator Work?

The calculator uses the HOMA-IR formula:

Where:

• Fasting Insulin — Measured in μU/mL (microinternational units per milliliter)
• Fasting Glucose — Measured in mg/dL (milligrams per deciliter)

Explanation: The formula estimates insulin resistance by assessing the relationship between fasting glucose and insulin levels.

3. Importance of HOMA-IR Calculation

Details: HOMA-IR is a valuable tool for assessing insulin resistance, which is associated with metabolic syndrome, type 2 diabetes, and cardiovascular disease risk.

4. Using the Calculator

Tips: Enter fasting insulin in μU/mL and fasting glucose in mg/dL. Both values must be positive numbers from valid laboratory tests.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal HOMA-IR value?
A: Typically, values below 1.0 indicate normal insulin sensitivity, while values above 2.0 suggest significant insulin resistance.

Q2: When should I test for HOMA-IR?
A: Testing should be done after an overnight fast (8-12 hours) for accurate results.

Q3: Are there limitations to HOMA-IR?
A: Yes, it's less accurate in people with impaired beta-cell function and may not reflect postprandial insulin dynamics.

Q4: Can HOMA-IR diagnose diabetes?
A: No, HOMA-IR assesses insulin resistance but should not be used alone to diagnose diabetes.

Q5: How often should HOMA-IR be measured?
A: Frequency depends on individual risk factors and should be determined by a healthcare provider.
