Final answer:
Cortisol is the hormone that explains the increase in various stress-related conditions and bodily changes in response to chronic stress and activation of the CRH gene promoter and the central norepinephrine system.
Step-by-step explanation:
The hormone responsible for increases in affective anxiety, eating disorders, mood cycles, and vulnerability to autoimmune and inflammatory diseases in women due to stimulation of the corticotropin-releasing hormone (CRH) gene promoter and the central norepinephrine system is cortisol. This glucocorticoid, produced in response to stress, influences a variety of physiological reactions, particularly affecting the immune system, mood, and metabolism, and alters glucose synthesis and fat catabolism. Chronic elevation of cortisol, due to prolonged or repeated stress, can result in numerous negative health outcomes, such as weakened immune function, depression, and increased inflammation.
