Symptoms of a high blood potassium level are nonspecific and predominantly related to muscular or cardiac function. The most common complaints are weakness, fatigue, palpitations and chest pain. Occasionally, a patient may complain of frank muscle paralysis or shortness of breath. Physical signs and vital signs generally may be normal, but muscle weakness, flaccid paralysis and depressed or absent deep tendon reflexes may be present. The main risk of high blood potassium levels are cardiac conduction abnormalities which can lead to cardiac arrest and death if untreated. If you are concerned regarding your potassium levels, I would advise an electrolyte level check with your family physician.
