                                Mild cases of low potassium often go unnoticed, but up to 20% of hospitalized people experience hypokalemia, the medical term for low potassium levels. A potassium deficiency can affect many vital bodily functions, including nerve signals, muscle contractions, and heart rhythm, which is why it is crucial to recognize the signs.
