What is the normal range for potassium levels in mEq/L?

The normal range for potassium levels in mEq/L is widely recognized as being between 3.5 and 5.5. Potassium is a crucial electrolyte in the body, playing a vital role in various physiological processes, including muscle contraction, nerve function, and maintaining fluid balance.

Within this normal range, levels below 3.5 mEq/L may indicate hypokalemia, which can lead to muscle weakness, arrhythmias, and other health issues. Conversely, levels above 5.5 mEq/L can indicate hyperkalemia, which can disrupt heart function and potentially lead to serious complications.

It is important for healthcare professionals to monitor potassium levels, especially in populations such as the elderly, who may be at higher risk for imbalances due to factors like kidney function decline or medication interactions. Understanding this normal range helps in the assessment and management of patients, ensuring that deviations from these levels are treated promptly and effectively.
