1. What is the HOMA-IR Calculation?

The HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) is a method used to quantify insulin resistance and beta-cell function. It provides a simple way to assess insulin resistance using fasting insulin and glucose levels measured in mg/dL units.

2. How Does the Calculator Work?

The calculator uses the HOMA-IR equation:

\[ HOMA-IR = \frac{Fasting\ Insulin\ (\mu U/mL) \times Fasting\ Glucose\ (mg/dL)}{405} \]

Where:

Fasting Insulin — Measured in micro units per milliliter (μU/mL)
Fasting Glucose — Measured in milligrams per deciliter (mg/dL)
405 — Constant denominator for the equation

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 metabolic syndrome, type 2 diabetes, cardiovascular disease, and other health conditions. Early detection allows for timely intervention and management.

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). 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 1.0-2.0 suggest mild insulin resistance, while values above 2.0 indicate significant insulin resistance.

Q2: When should HOMA-IR testing be done?
A: Testing should be performed after an overnight fast of 8-12 hours, preferably in the morning. Avoid testing after high-carbohydrate meals or strenuous exercise.

Q3: Are there limitations to HOMA-IR?
A: While useful for population studies and clinical screening, HOMA-IR may not be as accurate as more complex tests like hyperinsulinemic-euglycemic clamp in individual cases.

Q4: Can HOMA-IR be used for diabetes diagnosis?
A: HOMA-IR is primarily used to assess insulin resistance, not to diagnose diabetes. Formal diabetes diagnosis requires glucose tolerance tests or HbA1c measurements.

Q5: How often should HOMA-IR be measured?
A: Frequency depends on individual risk factors and clinical context. Generally, it may be measured annually for high-risk individuals or as part of metabolic health assessments.
