Adrenal glands are small, triangular glands located on top of both kidneys and are about the size of an index finger, measuring approximately half an inch in height and about three inches long. They interact with the hypothalamus and pituitary gland in the brain and produce important hormones that affect metabolism, chemicals in the blood, certain body characteristics and even psychological disposition and stability. Normally, these glands function properly and do not produce any physical symptoms. However, when the adrenal glands produce too much or too little of these hormones, they can have a negative effect on an individual’s health, including their ability to cope with physical and emotional stress.
