When the body experiences a cortisol deficiency, many of these key functions
are critically impeded, which can lead to serious illness, and even
death. Cortisol often regulates insulin, and in deficient states can
cause glucose-related shock. As a hormone that combats stress, it's lack
can also cause severe behavior disorders, making sufferers more prone to
irritability and panic. It is often linked to the severe condition
known as Addison's disease, where the adrenal glands continuously produce
limited amounts of necessary bodily hormones.
Cortisol deficiency occurs due to a malfunction of the adrenal gland, which is
located just above the kidneys and administers adrenal hormones directly into
the blood stream. Addison's, which is a hypoadrenal disease, is actually
a common cause of the condition, and cortisol deficiency is usually the first
sign that the glands are subsequently failing. Addison's is an autoimmune
disease that develops when the antibodies of the immune system attack the
adrenal glands, confusing them with being outside agents (the reason why this
happens is currently unknown). The attack usually leaves the adrenal gland
severely damaged, and often functioning at diminished capacity. Over
time, the adrenal glands can even, essentially, be killed.
Other hypoadrenal disorders can also cause cortisol deficiency, including
adrenocortison hormone deficiency, which is where the pituitary gland fails to
produce the hormones that trigger the function of the adrenal glands. This
can cause the adrenal glands to function sporadically, or to stop functioning
enitrely and eventually atrophy due to limited hormone stimulation.
Steroid use, either as a form of medical treatment, or due to the abuse of
performance enhancing drugs or aging treatments, can also impair the secretion
of adrenal hormones. These outside hormones, when administered to the
bloodstream, may confuse the adrenal gland into thinking that the system has
more hormones than it actually needs, and may cease functioning.
Symptoms of cortisol deficiency are exemplified by extreme dizziness, fatigue,
muscle weakness, weight loss, and headaches associated with low blood
sugar. Digestive symptoms also manifest, such as appetite reduction,
stomach cramping, diarrhea, and vomiting. Stress related conditions will
sometimes also manifest, such as depression, irritability, hair loss, and
fainting. Advanced cortisol deficiency is often distinguished by severe
states of bodily collapse.
Cortisol deficiency is fairly easy to diagnose outside of symptoms, as blood
tests can check for the presence of cortisol and other adrenal hormones quite
easily. Treatment is usually twofold: first the cause of the deficiency
must be addressed, especially if it caused by steroid medication or steroid
abuse. From there, the condition can be treated with cortisol replacement
therapy, which relies mainly on hydrocortisone. Often, however, cortisol
levels must be then monitored, as high levels of cortisol can, in turn, cause a
number of other ailments, such as increasing chances of osteoporosis and even
some forms of brain damage.
