Potassium can cause stomach upset, nausea, diarrhea, vomiting, intestinal gas, and other side effects. Too much potassium is UNSAFE and can cause feelings of burning or tingling, generalized weakness, paralysis, listlessness, dizziness, mental confusion, low blood pressure, irregular heart rhythm, and death.
Although a high blood potassium level usually does not produce symptoms or side effects, it may cause nausea and slow, weak or irregular pulse, according to MedlinePlus. In severe cases, the heart may stop. Muscle fatigue, weakness and paralysis can also occur, notes Mayo Clinic.
