Which one of the following is true of adrenal suppression due to steroid therapy –
**Core Concept**
Adrenal suppression is a condition where the adrenal glands do not produce sufficient cortisol and aldosterone due to prolonged use of corticosteroid medications. This leads to a decreased production of these essential hormones, which are crucial for maintaining blood pressure, regulating electrolyte balance, and responding to stress.
**Why the Correct Answer is Right**
The correct answer is related to the mechanism of adrenal suppression. When corticosteroids are administered exogenously, they occupy the glucocorticoid receptors in the adrenal gland, leading to a negative feedback inhibition of the hypothalamic-pituitary-adrenal (HPA) axis. This results in decreased production of adrenocorticotropic hormone (ACTH) and subsequently reduced cortisol production by the adrenal glands. As a result, the adrenal glands atrophy, and their ability to produce cortisol and aldosterone is impaired.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because adrenal suppression does not occur due to an increase in cortisol production. Instead, it is the opposite – a decrease in cortisol production that leads to adrenal suppression.
* **Option B:** This option is incorrect because adrenal suppression is not caused by an overproduction of aldosterone. Instead, it is the reduced production of aldosterone that leads to adrenal suppression.
* **Option C:** This option is incorrect because adrenal suppression does not occur due to an increase in ACTH production. Instead, it is the decreased production of ACTH that leads to adrenal suppression.
**Clinical Pearl / High-Yield Fact**
It is essential to remember that patients on long-term corticosteroid therapy require gradual tapering of the medication to avoid adrenal crisis, which can occur when the adrenal glands are unable to produce sufficient cortisol.
