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 provides an estimate of insulin sensitivity based on fasting glucose and insulin levels.

2. How Does the Calculator Work?

The calculator uses the HOMA-IR formula:

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

Where:

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

Explanation: The equation calculates insulin resistance by assessing the relationship between fasting insulin and glucose levels.

3. Importance of HOMA-IR Calculation

Details: HOMA-IR is crucial for assessing insulin resistance, which is associated with type 2 diabetes, metabolic syndrome, and cardiovascular diseases. It helps in early detection and monitoring of insulin sensitivity.

4. Using the Calculator

Tips: Enter fasting insulin in μU/L and fasting glucose in mmol/L. Both values must be valid (greater than 0). For accurate results, measurements should be taken after an overnight fast.

5. Frequently Asked Questions (FAQ)

Q1: What are normal HOMA-IR values?
A: Normal HOMA-IR values are typically below 2.0. Values above 2.0 may indicate insulin resistance, and above 2.5 suggest significant insulin resistance.

Q2: How often should HOMA-IR be measured?
A: It depends on individual risk factors and medical history. Generally, it's measured during routine check-ups or when monitoring metabolic health.

Q3: Are there limitations to HOMA-IR?
A: Yes, HOMA-IR may not be accurate in certain conditions such as type 1 diabetes, liver disease, or during pregnancy. It's best used as a screening tool rather than a definitive diagnostic measure.

Q4: Can HOMA-IR be used for children?
A: Yes, but reference ranges may differ. Consult pediatric guidelines for appropriate interpretation in children.

Q5: What factors can affect HOMA-IR results?
A: Recent food intake, stress, medications, and physical activity can affect results. Fasting for 8-12 hours is recommended before testing.
