Potassium is a major cation in the electrolytes of cells, helping to facilitate the contraction of skeletal and smooth muscles, including the contraction of the heart muscle. It is extremely important and indispensable in neuromuscular activities. So what is the normal blood potassium level?

Hypokalemia or low blood potassium is a condition in which the body cannot retain enough potassium to maintain normal functioning, which in some cases can lead to death. So what causes hypokalemia and how does it affect health?

Potassium plays an important role in the function of nerve cells and muscles including the heart muscle. Potassium electrolyte disturbances occur for many different reasons, this is a dangerous emergency that can lead to death if not detected and treated promptly.

Potassium disturbances are one of the most common electrolyte disturbances encountered clinically. Potassium affects nerve cells; when potassium levels are low, cells cannot polarize and release energy continuously, causing muscles and nerves to not function normally.
