How long does it take to correct hyponatremia?

In patients with severe symptomatic hyponatremia, the rate of sodium correction should be 6 to 12 mEq per L in the first 24 hours and 18 mEq per L or less in 48 hours.

Does drinking too much water cause hyponatremia?

Drinking excessive amounts of water can cause low sodium by overwhelming the kidneys ability to excrete water. Because you lose sodium through sweat, drinking too much water during endurance activities, such as marathons and triathlons, can also dilute the sodium content of your blood.
