Blood cortisol often clears in about 60–90 minutes, yet stress can keep levels higher by triggering repeated release and shifting binding and breakdown.

High cortisol often means your body is stuck in “alarm mode,” triggered by stress, medicines, or a hormone condition.

Cortisol is made in the adrenal glands, two small “caps” on top of the kidneys that release the hormone in daily pulses and during stress.

High cortisol can steer your body toward more belly fat and slower fat release, especially when levels stay high for weeks.

Cortisol is made mainly in the adrenal cortex atop each kidney, with release timed by brain signals and a daily rhythm.

Higher cortisol pushes the liver to make more glucose and can blunt insulin action, so blood sugar tends to run higher.

High cortisol can raise appetite, lift blood sugar, and steer fat toward the belly when sleep and recovery are off.

A timed cortisol blood draw maps levels across the day to flag unusually high or low patterns.

Use 27.59 to switch between serum µg/dL and nmol/L cortisol, then match the lab’s specimen and time window before you read ranges.

Cortisol rises before waking, peaks 30–45 minutes after you get up, then drops through the day toward its lowest point late evening.
