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

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

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, cardiovascular disease, and other health conditions. It helps in early detection and monitoring of insulin resistance.

4. Using the Calculator

Tips: Enter fasting insulin in μU/mL and fasting glucose in mg/dL. Both values must be greater than zero. For accurate results, measurements should be taken after an overnight fast of 8-12 hours.

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: Frequency depends on individual risk factors. People with risk factors for insulin resistance may benefit from annual testing, while those with diagnosed conditions may need more frequent monitoring.

Q3: Are there limitations to HOMA-IR?
A: Yes, HOMA-IR is less accurate in people with type 1 diabetes, those taking certain medications, or individuals with extreme glucose or insulin levels. It provides an estimate rather than a direct measurement.

Q4: Can HOMA-IR be used for diagnosis?
A: While HOMA-IR is a useful screening tool, diagnosis of insulin resistance should be confirmed with additional tests and clinical evaluation by a healthcare professional.

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