Cortisol is a hormone produced by the adrenal glands, which are
located just above the kidneys. Cortisol affects almost every organ in the body
and is important for body functions such as breaking down glycogen and fat for
energy, managing stress, and maintaining blood pressure.
levels increase when the pituitary gland in the brain releases another hormone
called adrenocorticotropic hormone (ACTH). Cortisol levels also rise during
times of stress.
