Evidence check: Insulin in the context of stress

The provided context does not directly address insulin in the context of stress. However, established human physiology shows that stress hormones (cortisol, adrenaline) raise blood glucose, and chronic stress can promote insulin resistance via increased cortisol and inflammation. Human studies (e.g., on shift workers or chronic stress) demonstrate moderate associations between stress markers and elevated fasting insulin or HOMA-IR. The evidence level is human-moderate, but no specific sources from the given context support this. Consumer tests (DNA, blood) from MyBody-X may include markers like fasting insulin or SNPs related to insulin sensitivity (e.g., TCF7L2), but effect sizes are small and results are not diagnostic. For clinical assessment, a doctor should evaluate stress-related metabolic changes using validated tests (e.g., OGTT, cortisol rhythm). The evidence rating reflects general medical knowledge, not the provided context. Caution: Do not self-adjust medications or supplements based on home test results.
