Too much potassium can affect the way your heart works, causing symptoms like arrhythmia (an abnormal rhythm), palpitations or skipped heartbeats, and, ultimately, cardiac arrest. If you have any reason to think you might be having cardiac symptoms, get to a doctor immediately. High potassium levels can lead to an upset stomach, nausea, and vomiting. These symptoms can lead to dehydration. Potassium helps muscles function, so if you have too much or too little, your muscles can weaken, making you feel weak, tired, and lethargic. This feeling may be exacerbated by other symptoms, especially vomiting. Feelings of numbness or tingling are also related to muscle activity. You may notice these sensations first in your extremities (the hands and feet) and then around your mouth; this may be followed by muscle twitching. Get medical help if you have these symptoms. Many people have no symptoms and only discover the high potassium levels when their doctors run blood tests.
