Adrenal gland disfunction is quite noticeable, as it controls blood sugar, energy levels, sleep habits and stress reactions. Often, adrenal exhaustion is brought on by major stress or fatigue. Consistent stressors found in our world today can bring about chronic stress, which leads to excessive fatigue, as our bodies cannot return to normal often enough.
Cortisol is produced by the adrenal glands. It is released in response to stress and controlled by the hypothalamus. Most of us have high levels of cortisol due to our high stress lifestyles. Sustained cortisol release can raise your blood pressure and sap your energy. In the short term, high levels of cortisol can create insulin resistance, weight gain and decrease your immunity to illness and disease. Long term, it can lead to stroke, heart attack or diabetes.
DHEA, also produced by the adrenal gland, moves through the blood and can turn into other hormones like testosterone and estrogen. Known as a precursor hormone, DHEA is vital to sexual development.
