Is Cortisol useful for Blutzucker?

Cortisol is a key stress hormone that raises blood glucose via gluconeogenesis and insulin resistance. Thus, measuring cortisol can help identify stress-related blood sugar dysregulation. However, a single cortisol test (saliva or blood) provides only a snapshot and is not sufficient for diabetes diagnosis. MyBody-X offers cortisol tests that may be useful as part of a holistic stress and metabolic monitoring approach. The evidence for cortisol's effect on blood sugar is strong (human-strong), but clinical application requires repeated measurements and medical interpretation. Caveat: Not a replacement for HbA1c or fasting glucose.
