It affects metabolism, the immune system, blood pressure, and blood glucose levels. Abnormalities in cortisol levels can be associated with both physiological factors and serious diseases.<\/p>\n<h2 data-start=\"416\" data-end=\"465\"><strong data-start=\"419\" data-end=\"463\">What is cortisol and why is it needed?<\/strong><\/h2>\n<p data-start=\"467\" data-end=\"606\">Cortisol is a hormone that belongs to the glucocorticoid group. Its secretion is controlled by the hypothalamic-pituitary-adrenal axis:<\/p>\n<ol data-start=\"608\" data-end=\"861\">\n<li data-start=\"608\" data-end=\"671\">The hypothalamus secretes corticoliberin, which stimulates the pituitary gland.<\/li>\n<li data-start=\"672\" data-end=\"761\">The pituitary gland produces adrenocorticotropic hormone (ACTH), which activates the adrenal glands.<\/li>\n<li data-start=\"762\" data-end=\"861\">The adrenal glands produce cortisol, which enters the bloodstream and acts on various organs and systems.<\/li>\n<\/ol>\n<p data-start=\"863\"
