Adrenal insufficiency is generally divided into two main types:
1. Primary Adrenal Insufficiency (Addison's Disease)
This condition is characterized by damage to the adrenal cortex, the outer layer of the adrenal glands, which results in insufficient production of adrenocortical hormones. It typically arises from an autoimmune disease, where the immune system mistakenly attacks and destroys the adrenal cortex. Individuals with Addison's disease are more likely to have other autoimmune conditions.
2. Secondary Adrenal Insufficiency
Secondary adrenal insufficiency results from inadequate stimulation of the adrenal glands due to diseases affecting the pituitary or hypothalamus glands. These glands are responsible for secreting adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands. Additionally, the sudden discontinuation of corticosteroid medications used to treat chronic conditions like asthma or arthritis can lead to temporary secondary adrenal insufficiency.
