In severe cases, hypernatremia can lead to coma and death. Hypotonic dehydration (hyponatremia). Hyponatremia is what happens when you have too little sodium in your body.

Hyponatremia and hypernatremia are primarily disorders of water metabolism, said Dr. David Mount, a kidney specialist and clinical chief of the renal division at Brigham and Women's Hospital in ...

Two common causes of hypernatremia are not enough fluid intake and too much water loss. In rare cases, consuming too much sodium can cause hypernatremia. The opposite of hypernatremia is hyponatremia.

Hyper- and hyponatremia occur frequently in extremely preterm infants. Our purpose was to investigate plasma sodium (P-Na) concentrations, the incidence of hyper- and hyponatremia, and the impact ...

Limiting correction of chronic hypernatremia so that the plasma sodium concentration is decreased by less than 0.5 mmol per liter per hour reduces the risk of cerebral edema and seizures ...

Hypernatremia is a possible complication of diabetes insipidus. It generally refers to when sodium levels in the blood are more than 145 milliequivalents per liter (mEq/L).

People with adipsic diabetes insipidus are at a high risk of life threatening hypernatremia. Research indicates that fewer than 100 severe cases have been reported in about the past 40 years.

Hypernatremia at any point during hospitalization was associated with increased mortality in COVID-19; hyponatremia was linked to greater need for ventilatory support.

Compared with non-COVID-19 cases with normonatremia hospitalized in 2019, COVID-19 cases with moderate or severe hyponatremia, mild hyponatremia, normonatremia, and hypernatremia at admission had ...

Hypernatremia can occur rapidly (within 24 hours) or develop more slowly over time (more than 24 to 48 hours). The speed of onset will help your doctor determine a treatment plan.
