The Physiology of Cortisol: More Than a Stress Hormone

Cortisol is a glukocorticoid is a costed produced by by they zona fasciculata of te e adrenal cortex. Its secretion is governed the hypothalamic- pituitary -adrenyl (HPA) axis, which chich follows a distint circadian rhythm.

Cortisol andGlucose Metabolism

Of cortisol 's primary metabolic functions is to ensure an suple of glucose for the brain body during period of stress or fasting. It accesses this by stimulating gluconeogenesis in thee liver, promoting the breakdown of clyogen, and reducing districheral glucose uptaka in muscle and adipose tissue. These actions presenge blood glucose levels. In the short term, thies responses ive; ive providevides thee energy need dee handle.

In healty individuals, this system keeps cortisol levels in check.

Estrogen enhances insulin sensitivity, promotes glucose uptake in szkielet muscle, and supports healty body fat distribution (subcutanous rather than visceral).

The Cortisol- Diabetes Connection: Mechanisms andPathways

Te link between cortisol and type 2 diabetes in postmenopausal women is complex, involving multiple, interrelated mechanisms. Zrozumiałe, że pathways pomaga wyjaśnić, dlaczego stres management i lifestyle interventions can be so effective in this population.

Insulin Resistance

Cortisol directly directly indicles insulin by reducing thee translocation of glucose transported type 4 (GLUT4) to te te cell surface in muscle and fat cells. It also increates lipolysis, leading to o higher circulating free fatty acids, which further blunt insulin signaling. Over time, thee pantas must secrete more insulin to maintain normal glucose levels. This recompatiatory hiperinemia ia hallmark of insulin resistance, procursor tsai.

Increvased Gluconeogenesia

Eun in thee fasting state, cortisol dribs the liver to produce glucose from non-carbohydrate precursors (amino acids, glyceriol, lactate). This is beneficial during short-term starvation or stres but becomes pathological wheen sustaged. Postmenopausal women with elevated cortisol often exhibit higher rates of endogenous glucose production, contribuining to fasting hyperglycemica.

Impaired Pancreatic Beta- Cell Function

Chronic cortisol exposure may also directly damage thee chapatic beta cells that produce insulin.
