Answer

Many individuals with hyperkalemia are asymptomatic. When present, the symptoms of hyperkalemia are nonspecific and predominantly related to muscular or cardiac function. The most common complaints are weakness and fatigue. Occasionally, a patient may complain of frank muscle paralysis or shortness of breath. Patients also may complain of palpitations or chest pain. Patients may report nausea, vomiting, and paresthesias. The history is most valuable in identifying conditions that may predispose to hyperkalemia.
