Adrenal insufficiency is fundamentally divided into two main categories:
Primary Adrenal Insufficiency (Addison's Disease)
This type of adrenal insufficiency is known as Addison's disease. It occurs when the adrenal cortex (the outer layer of the adrenal glands) is damaged and cannot produce sufficient adrenocortical hormones. Most often, it is an autoimmune disease resulting from the body's immune system mistakenly attacking the adrenal cortex as foreign tissue. This autoimmune attack leads to the destruction of the cortex. Individuals with Addison's disease have a higher risk of developing other autoimmune diseases compared to the general population.
Secondary Adrenal Insufficiency
This condition arises from insufficient stimulation of the adrenal glands. It typically results from a deficiency in the production of ACTH (Adrenocorticotropic Hormone), the hormone that stimulates the adrenal glands, due to diseases affecting the pituitary or hypothalamus glands. Furthermore, abruptly stopping corticosteroids, used for treating chronic conditions like asthma or arthritis, can lead to temporary secondary adrenal insufficiency.
