Insulin (Fasting) Test

Is this the same as a glucose test?

No — a glucose test measures sugar directly in the blood, while this test measures the insulin hormone that regulates it. They're often interpreted together to assess insulin resistance.

What is HOMA-IR?

HOMA-IR is a calculation that combines your fasting glucose and fasting insulin values into a single score estimating how insulin-resistant your body currently is.

Can insulin resistance be reversed?

In many cases, yes — lifestyle changes such as weight loss, regular exercise, and dietary changes can meaningfully improve insulin sensitivity, particularly when addressed early.
