We review evidence for being obese risks role of glucocorticoids in activating the central stress-response network, and for mediation of this network by corticotropin-releasing factor CRF. High-cortisol responder sheep exhibit reactive coping strategies, whereas LRs exhibit proactive coping strategies. When there are high glucocorticoids together with a chronic stressor, the steroids act in brain in a feed-forward fashion to recruit a stress-response network that biases ongoing autonomic, neuroendocrine, and behavioral outflow as well as responses to novel stressors.

High-cortisol responder sheep exhibit reactive coping strategies, whereas LRs stresa proactive coping strategies. AU - Warne, James P. AB - Glucocorticoids either inhibit or sensitize stress-induced activity in the hypothalamo-pituitary-adrenal HPA axis, depending on time after their administration, the concentration of the steroids, and whether there is a concurrent stressor input. In particular, glucocorticoids are known to increase the consumption of foods enriched in fat and sugar.

Phenotypes of mouse diabetes and rat fatty due to mutations in the OB leptin receptor. It is conceivable that in the context of stressful circumstances, obesity as poverty or unemployment, the effects of the stress hormone cortisol may cause extra harm in individuals carrying the NS variant. Catecholamines are also linked to the hypothalamic-pituitary-adrenal HPA axis with its end-product cortisol, which responds within minutes to hours and supports the action of catecholamines. The role of glucocorticoids in obesity is poorly understood.

BMJ : 82 — The effect on strwss features of the metabolic syndrome, including hypertension, dyslipidemia, and obesity, and obesity thus far also modest [ 82 ]. It is now clear that the response to stress or to glucocorticoid feedback is not of equal magnitude around the clock but that windows of sensitivity exist.
