Hypokalemia

Hypokalemia is a common electrolyte disturbance defined as a serum or plasma potassium concentration below 3.5 mEq/L (or mmol/L) It develops when potassium is depleted through excessive renal losses, gastrointestinal losses, transcellular shifts of potassium into cells, or, less frequently, inadequate dietary intake

The condition primarily impacts neuromuscular and cardiovascular function by hyperpolarizing resting membrane potentials and altering cellular excitability While mild reductions are often asymptomatic, severe depletion can manifest clinically as muscle weakness, fatigue, cramping, hyporeflexia, paralytic ileus, cardiac conduction delays, and potentially life-threatening ventricular arrhythmias or respiratory paralysis
