1. What is the HOMA-IR Equation?

The HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) equation estimates insulin resistance using fasting insulin and glucose levels. It provides a simple method to assess insulin sensitivity and identify potential metabolic disorders.

2. How Does the Calculator Work?

The calculator uses the HOMA-IR equation:

Where:

• \( Fasting\ Insulin \) — Fasting insulin level (μU/mL)
• \( Fasting\ Glucose \) — Fasting glucose level (mg/dL)

Explanation: The equation calculates insulin resistance by assessing the relationship between fasting insulin and glucose levels, with higher values indicating greater insulin resistance.

3. Importance of HOMA-IR Calculation

Details: HOMA-IR assessment is crucial for identifying insulin resistance, which is associated with type 2 diabetes, metabolic syndrome, 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 valid (greater than 0). Use morning fasting blood test results for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal HOMA-IR value?
A: Typically, values below 2.0 are considered normal insulin sensitivity, while values above 2.9 may indicate insulin resistance.

Q2: Can I calculate HOMA-IR at home?
A: Yes, with lab values from blood tests. You need fasting insulin and glucose results from laboratory testing.

Q3: When should I get tested for HOMA-IR?
A: Morning fasting blood samples after 8-12 hours of fasting provide the most accurate results.

Q4: Are there limitations to HOMA-IR?
A: HOMA-IR may be less accurate in certain populations, such as those with type 1 diabetes or advanced liver disease.

Q5: How often should HOMA-IR be measured?
A: For monitoring purposes, it's typically measured every 3-6 months when making lifestyle or medication changes.
