The Symptoms of Excess Potassium

Excess potassium, also known as hyperkalemia, can potentially be fatal. Potassium is an electrolyte that is essential for the body to function, but the balance of potassium in the body is very delicate. It is used in the cells and is required for proper function of the nerve and muscle systems.

  1. Causes

    • High levels of potassium can be caused by problems with the kidneys, medications such as potassium-sparing diuretics, NSAIDs, ACE inhibitors, potassium supplements, Addison's disease, diabetes, lupus nephritis or tissue trauma.

    Primary symptoms

    • Increased blood potassium levels can cause nausea, stomach cramps, diarrhea, shortness of breath, confusion, faintness, fatigue, muscle weakness, tingling in the extremities, seizures, convulsion and paralysis. As potassium levels build up, the heartbeat can become weak, uneven and actually stop.

    Chronic symptoms

    • Left untreated or undiagnosed, high levels of potassium in the blood can cause problems with blood pressure, kidney and heart function, artherosclerosis and the digestive system.

    Considerations

    • Symptoms of excess potassium may not show up until it reaches dangerous levels.

    Warning

    • Left untreated high potassium can be fatal, so get medical attention as soon as any symptoms occur.
