Potassium deficiency can lead to hypokalemia — low blood potassium, less than 3.5 millimoles per liter of blood (mmol/L) — which can cause a variety of signs and symptoms, including tiredness, loss of focus, loss of appetite, vomiting, and muscle weakness.[1][2][3] In more serious cases, hypokalemia can also lead to heart arrhythmias, including atrial fibrillation),[2][3][4][5][6] and is associated with an increased risk of cardiovascular-related mortality.[7][8][9]
