Chronic adrenal insufficiency is characterized by all of the following except –
**Core Concept**
Chronic adrenal insufficiency, also known as Addison's disease, is a condition where the adrenal glands do not produce sufficient cortisol and/or aldosterone hormones. This can lead to a range of systemic symptoms and complications. The adrenal glands are responsible for producing these vital hormones, which play a crucial role in regulating metabolism, electrolyte balance, and the body's response to stress.
**Why the Correct Answer is Right**
Chronic adrenal insufficiency typically presents with fatigue, weight loss, hypotension, hyperpigmentation of the skin, and hypoglycemia. The lack of cortisol production impairs the body's ability to respond to stress, leading to decreased blood pressure and glucose levels. The absence of aldosterone production disrupts electrolyte balance, causing hyperkalemia and hyponatremia.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because hyperglycemia is actually a characteristic of Cushing's syndrome, a condition caused by excess cortisol production, not chronic adrenal insufficiency.
**Option B:** This option is incorrect because hyperkalemia and hyponatremia are common electrolyte imbalances seen in chronic adrenal insufficiency due to the lack of aldosterone production.
**Option C:** This option is incorrect because hypotension is a common manifestation of chronic adrenal insufficiency, resulting from the decreased production of cortisol and aldosterone.
**Clinical Pearl / High-Yield Fact**
In chronic adrenal insufficiency, the skin hyperpigmentation is often more pronounced in areas exposed to the sun, such as the face, hands, and feet.
**Correct Answer:** A.
