We have a direct correlation between gambling and neurochemical changes in our central nervous system. In relation to the "fight or flight" phenomenon, gamblers secrete much more Dopamine than a non gamblers thus producing electrophysiological and cognitive disturbances. Along with Dopamine receptors, we also increase our cortisol levels which is a "stress" hormone. When cortisol levels rise, our blood glucose is consumed so our brain tells us we need more sugar to compensate for our losses which is why we tend to crave simple carbs/sugars. I could write a thesis on this shit but you get the picture.
"stress" hormone.
just to clarify what this means, it is a hormone that is RELEASED in response to stress to RESTORE homeostasis.It is a stress protection hormone. It is ANTI-STRESS, it activates anti-stress pathways.
It actually increases blood sugar levels, by gluconeogenesis.
It is essential for life.
Having a blood test for Cortisol should only be required for the diagnosis and treatment of disorders of the adrenal gland.
