NOT a feature of primary hyperaldosteronism is
**Primary Hyperaldosteronism Features**
**Core Concept**
Primary hyperaldosteronism is a condition characterized by excess production of aldosterone, a mineralocorticoid hormone produced by the adrenal glands. This excess leads to sodium retention, potassium excretion, and hypertension.
**Why the Correct Answer is Right**
The correct answer is not a feature of primary hyperaldosteronism. Primary hyperaldosteronism typically presents with hypertension, hypokalemia (low potassium levels), and metabolic alkalosis (elevated blood pH). The condition is often caused by an aldosterone-producing adenoma (APA) or bilateral adrenal hyperplasia.
**Why Each Wrong Option is Incorrect**
**Option A:** Hypokalemia is indeed a feature of primary hyperaldosteronism, as aldosterone promotes potassium excretion.
**Option B:** Metabolic alkalosis is also a characteristic feature of primary hyperaldosteronism, resulting from increased sodium reabsorption and potassium excretion.
**Option C:** Hypertension is a hallmark of primary hyperaldosteronism due to sodium retention and volume expansion.
**Clinical Pearl / High-Yield Fact**
Primary hyperaldosteronism can be difficult to diagnose, but the presence of hypokalemia and metabolic alkalosis in a hypertensive patient should raise suspicion for this condition.
