1. What is the HOMA-IR Calculator?

The HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) calculator estimates insulin resistance using fasting insulin and glucose levels. It's a simple, non-invasive method to assess insulin sensitivity and identify individuals at risk for metabolic disorders.

2. How Does the Calculator Work?

The calculator uses the HOMA-IR equation:

\[ HOMA-IR = \frac{\text{Fasting Insulin} \times \text{Fasting Glucose}}{22.5} \]

Where:

Fasting Insulin — Measured in μU/mL (microinternational units per milliliter)
Fasting Glucose — Measured in mmol/L (millimoles per liter)
22.5 — Normalization constant

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 is crucial for identifying insulin resistance, which is associated with type 2 diabetes, metabolic syndrome, cardiovascular disease, and polycystic ovary syndrome (PCOS).

4. Using the Calculator

Tips: Enter fasting insulin in μU/mL and fasting glucose in mmol/L. Both values must be greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal HOMA-IR value?
A: Typically, values below 1.0 indicate normal insulin sensitivity, 1.0-1.9 suggest mild insulin resistance, and values above 2.0 indicate significant insulin resistance.

Q2: When should I get tested?
A: Testing should be done after an overnight fast (8-12 hours) for accurate results. Avoid testing after illness or significant stress.

Q3: Are there limitations to HOMA-IR?
A: While useful for population studies, HOMA-IR may not be as accurate for individuals with impaired beta-cell function or those taking certain medications.

Q4: 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 aimed at improving insulin sensitivity.

Q5: Can HOMA-IR be used for diagnosis?
A: HOMA-IR is a screening tool rather than a diagnostic test. Clinical diagnosis should be confirmed with additional tests and medical evaluation.
