You have two adrenal glands; they’re about the size of your thumb and sit on top of each of your kidneys.
The adrenal glands play a large role in human physiology. They secrete more than 50 hormones, some of which are essential for life. They help regulate blood sugar and blood pressure, help in protein and fat metabolism, support proper cardiovascular and gastrointestinal functioning and have a major responsibility in responding to stress.
When these tiny adrenal glands are subjected to a constant, even low level of stress, they can easily become overworked. Symptoms of adrenal fatigue (aka hypoadrenia) are non-specific; they are general in nature and are present in many conditions. There is no specific medical test for adrenal fatigue. That may be why adrenal fatigue is often overlooked until it has become severe. Doctors often do not acknowledge adrenal problems unless there is extremely little functioning (Addison’s disease) or way too much (Cushing’s disease).
