In brief: Hypo

Potassium is needed to help muscle function.
Without enough potassium, there is a change in the conduction of cells within a muscle. This change can lead to cramping, weakness and even heart arrythmias. People who have poor diets or who take diuretics "water pills" can develop hypokalemia more often.
