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, providing an estimate of insulin sensitivity.

2. How Does the Calculator Work?

The calculator uses the HOMA-IR formula:

Where:

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

Explanation: The formula calculates insulin resistance by assessing the relationship between fasting glucose and insulin levels. Higher values indicate greater insulin resistance.

3. Importance of HOMA-IR Calculation

Details: HOMA-IR is an important tool for assessing metabolic health, identifying insulin resistance, and monitoring response to treatments for conditions like type 2 diabetes and metabolic syndrome.

4. Using the Calculator

Tips: Enter fasting insulin in μU/mL and fasting glucose in mg/dL. Both values must be positive numbers. For accurate results, use values from a true fasting state (typically 8-12 hours without caloric intake).

5. Frequently Asked Questions (FAQ)

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

Q2: How often should HOMA-IR be measured?
A: This depends on individual health status. People with metabolic conditions might test quarterly, while healthy individuals might test annually or as recommended by their healthcare provider.

Q3: Are there limitations to HOMA-IR?
A: Yes, HOMA-IR is less accurate in people with type 1 diabetes, those with advanced liver disease, and during pregnancy. It's also less reliable at extreme values of insulin resistance.

Q4: Can HOMA-IR be used to diagnose diabetes?
A: No, HOMA-IR assesses insulin resistance but is not a diagnostic tool for diabetes. Diagnosis requires specific glucose tolerance tests or HbA1c measurements.

Q5: How can I improve my HOMA-IR score?
A: Lifestyle modifications including regular exercise, weight management, and a balanced diet low in processed sugars can help improve insulin sensitivity and lower HOMA-IR values.
