Is hypokalemia life threatening?

A normal blood potassium is 3.6 to 5.2 mmol/L. Severe and life threatening hypokalemia level is known as <2.5mmol/L. Since potassium is critical to the proper functioning of nerve and muscle fibers, hypokalemia can require urgent medical attention.

Accordingly, can hypokalemia lead to death?

Hypokalemia is associated with increased risk of arrhythmia in patients with cardiovascular disease, as well as increased all-cause mortality, cardiovascular mortality and heart failure mortality by up to 10-fold. Long-term potassium homeostasis depends on renal potassium excretion.
