Hyperkalemia, defined as a serum potassium concentration greater than 5.0–5.3 mEq/L, is rare in a general population of healthy individuals. In hospitalized patients, the incidence of hyperkalemia has ranged from 1% to 10%, depending on how the condition is defined. In hospitalized patients, drugs are implicated in the development of hyperkalemia in as many as 75% of cases. Decreased renal function, [15] genitourinary disease, cancer, severe diabetes, and polypharmacy may also predispose to hyperkalemia.
