How long does it take to recover from hypernatremia?
In the case of acute hypernatremia, which presents within 24 hours duration, serum sodium levels can be corrected in the next 24 hours, provided that the required treatment has been started. In the case of chronic hypernatremia, sodium levels should be corrected within 48 hours duration. Overall, it is critical to avoid rapid correction of sodium levels to prevent brain edema.
