What is the normal sodium level (Na+) in mEq/L?

The normal sodium level typically falls within the range of 130-145 mEq/L. Sodium is a crucial electrolyte that plays a vital role in maintaining fluid balance in the body, as well as in muscle and nerve function. Values below this range may indicate hyponatremia, which can lead to a variety of health issues, including neurological symptoms due to brain edema. Conversely, levels above this range can signify hypernatremia, which may result in dehydration, increased thirst, and potentially severe complications. Thus, understanding this normal range is important for clinical decision-making and patient management, particularly in critical care settings where electrolyte balance is vital to patient outcomes.
