2. Symptoms of High Potassium

For patients who are unaware of a high potassium issue, there may be no apparent symptoms at all. Once the levels reach a dangerous level, the symptoms become clear. The most common complaints with high potassium levels are of fatigue and weakness. Other symptoms include abnormal heart rhythm, a slow heart rate, nausea and vomiting, and chest pains. High levels are usually confirmed with bloodwork and treated with IV calcium or insulin and glucose to help flush the excess potassium.
