The Triglyceride-Glucose (TyG) Index has emerged as a reliable and practical marker for identifying insulin resistance, an important factor in the development of type 2 diabetes and cardiovascular disease.

To calculate the TyG Index, enter the fasting triglyceride level (mg/dL) and the fasting blood glucose level (mg/dL). The calculator applies the formula:

TyG Index = ln(Triglycerides × Glucose) / 2

This calculation provides a validated estimate of insulin resistance and has been shown in research to correlate strongly with more complex measures of metabolic dysfunction.

The TyG Index is a valuable resource for healthcare professionals seeking to assess risk for diabetes and cardiometabolic disease, as well as for individuals monitoring their own metabolic health. By offering insight into insulin resistance, the TyG Index can help guide lifestyle modifications, nutritional interventions, and therapeutic strategies that support better long-term health outcomes.
