HPA Axis.
The HPA involves interactions between the hypothalamus located in the brain, the pituitary gland located just beneath the brain and the adrenal cortex, part of the adrenal gland - we have two of these located close to our kidneys.
When the body is experiencing stress, the HPA axis is stimuated, this is done by the hypothalamus which sends messages via neurotransmitters and stimulates the secretion of the hormone adrenocorticotrophic hormone from the pituitary gland. In turn ACTH travels to the adrenal glands where it stimulates the adrenal cortex, in doing so the adrenal cortex releases glucorticoids which increase blood sugar levels to provide more energy.
Being continuously exposed to stress means a constant production of glucorticoids, having a prolonged increase in blood sugar levels may lead to more serious illnesses such as diabetes.
