The Fasting Insulin test measures the level of insulin in your blood after an overnight fast. Insulin is a hormone that regulates blood sugar levels and plays a critical role in metabolism. Abnormal fasting insulin levels can indicate insulin resistance, which is a precursor to type 2 diabetes and metabolic syndrome. This test is important for understanding how well your body manages glucose and can help inform dietary and lifestyle changes to improve your metabolic health.

Reasons to Check It:
"Fasting insulin is the hormone released by your pancreas that helps remove glucose from your bloodstream and into your body’s cells where it can be used for fuel. An insulin measurement may help determine whether a high glucose reading is the result of insufficient insulin production (as in insulin-dependent diabetes) or poor use of insulin (as in Type 2 Diabetes). Elevated levels of insulin can indicate the beginning of Insulin Resistance Syndrome and is typically the first warning sign of potential overload of the pancreas.
Insulin resistance leads to excess sugar in the blood stream, and over time this can lead to diabetes. High levels of insulin increase cardiovascular risk by 1.5-2x in non-diabetics." - Dr. Alan Hopkins
