Hypokalemia.may be a feature of all following diseases, except –
**Core Concept**
Hypokalemia refers to a serum potassium level below 3.5 mmol/L, often resulting from excessive potassium loss or inadequate potassium intake. It can be caused by various factors, including hormonal imbalances, renal dysfunction, and medications.
**Why the Correct Answer is Right**
Hypokalemia can be a feature of several conditions, including primary aldosteronism, Cushing's syndrome, and Bartter syndrome. In primary aldosteronism, excessive aldosterone production leads to potassium wasting in the urine. In Cushing's syndrome, the excess cortisol promotes potassium loss by increasing mineralocorticoid activity. Bartter syndrome is characterized by mutations in the genes encoding for the sodium-potassium-chloride cotransporter, leading to renal potassium wasting.
