Hypernatremia: Is when there's too

Hypernatremia is when there's too much sodium and not enough water in your blood. It can be caused by dehydration, certain health conditions, or taking in too much salt. Learn how to prevent, diagnose, and treat this electrolyte imbalance. Introduction Hypernatremia, serum sodium concentration ( [Na +]) of >145 mmol/L, represents a state of total body water deficiency absolute or relative to total body Na + and potassium. It can result from (1) water loss (e.g., diabetes insipidus [DI]), (2) hypotonic fluid loss (osmotic diarrhea), or (3) hypertonic fluid gain (Na + -containing fluids). Hypernatremia often occurs in pediatric, geriatric, and critically ill patients. Hypernatremia induces diverse effects in multiple organ ... Hypernatremia is a condition where sodium levels in the blood are too high. It can result from dehydration, fluid loss, or certain health issues. Learn about the causes, symptoms, diagnosis, treatment, and prevention of hypernatremia. Hypernatraemia from free water loss causes dehydration as intracellular water is drawn out of cells into the extracellular fluid (ECF) preserving the latter to a large extent; however, if sodium is lost as well as water then significant hypovolaemia (reduction in ECF volume) can also occur.
