Glucocorticoids (primarily cortisol) and mineralocorticoids are two important types of hormones produced by the body's adrenal glands. (glencoeanimalhospital.com)
Under normal conditions, the brain releases a hormone called adrenocorticotropic hormone ( ACTH ) that stimulates the adrenal glands to release their hormones. (glencoeanimalhospital.com)
Addison's disease occurs when either the brain doesn't release adequate amounts of ACTH, or the adrenal glands fail to release their hormones in response to ACTH. (glencoeanimalhospital.com)
The body has highly developed systems called feedback mechanisms that control how much of these hormones the adrenal glands produce and release, based on the body's needs. (glencoeanimalhospital.com)
In contrast, when the body is receiving cortisol from an outside source (like a cortisone pill or injection), it reduces the amount of cortisol that the adrenal glands produce. (glencoeanimalhospital.com)
Sometimes, the body's immune system can damage the adrenal glands' cells so extensively that they can't release hormones when they need to. (glencoeanimalhospital.com)

Addison's disease is a condition, known as hypoadrenocorticism, where the adrenal glands (located above the kidneys) do not produce enough of two steroid hormones, called cortisol and aldosterone. (kihorsemed.com)
Hypoadrenocorticism, or Addison's disease, results from insufficient secretion of steroid hormones (glucocorticoids and mineralocorticoids) from the adrenal glands. (omia.org)
Cortex15

The outer zone, the neocortex, develops into the mature adrenal cortex, which is only 15% of the total volume. (medscape.com)
In addition to its role in providing precursors for placental estrogen formation, the fetal adrenal cortex may participate in the events that lead to the initiation of labor and to maturation of the fetal lungs. (medscape.com)
Addison's disease causes your dog's immune system to damage the adrenal cortex such that it cannot produce enough cortisol and aldosterone to maintain normal bodily function. (veterinarians.org)
For whatever reason, your dog will undergo an auto-immune response that causes the destruction of the cells in the adrenal cortex, which is a specific layer in the gland responsible for the production of cortisol. (purepetfood.com)
Similarly, low steroid levels send a signal to Hypothalamus to increase the ACTH-RH and also to pituitary to increase the ACTH secretion, which in turn helps the Adrenal cortex to increase the steroid secretion. (mutalikpharmacology.com)
Corticosterone is a glucocorticoid secreted by the cortex of the adrenal gland. (teitell-lab.com)
Corticosterone is produced in response to the stimulation of the adrenal cortex by adrenocorticotropic hormone (ACTH) and is the precursor of aldosterone. (teitell-lab.com)
In primary hypoadrenocorticism the disease is due to changes to the adrenal cortex, while secondary hypoadrenocorticism refers to deficiency of ACTH, produced in the pituitary gland. (omia.org)

After the blood sample is collected, a prophylactic dose of glucocorticoid may be considered for patients with high risk for acute adrenal insufficiency. (nih.gov)
An intact HPA axis function is generally indicated by an increase in 11‑desoxycortisol to over 70 mcg/L. Because of an overlap between a normal ACTH response and an abnormal ACTH response, the ACTH response alone cannot be used to distinguish between healthy individuals and those with adrenal insufficiency. (nih.gov)
If for any reason, this individual stops taking steroids abruptly, then because there is no time for the tissues to regain the suppressed HPA axis function, the individual can suffer from Acute Adrenal Insufficiency, a potentially dangerous condition of deficiency of steroids.

Addison's disease is when a dog's adrenal gland doesn't produce enough steroid hormones. (purepetfood.com)
Primary Addison's means that the disease has been caused by a problem with the adrenal gland itself. (purepetfood.com)
Whereas secondary Addison's disease is caused by a problem in the pituitary gland, which is what stimulates the adrenal gland to create hormones. (purepetfood.com)
Even if a dog's adrenal gland is healthy, if their pituitary gland has a problem and isn't sending the signals to trigger the gland to work, their body still won't produce the hormones they need. (purepetfood.com)
Addison's disease is caused by the dog's immune system attacking and destroying the cells of their adrenal gland. (purepetfood.com)
