What are the treatments for hyponatremia?
Severe hyponatremia can be treated by infusing a solution of 5% sodium chloride in water into the bloodstream. Moderate hyponatremia due to use of diuretics or an abnormal increase in vasopressin is often treated by instructions to drink less water each day. Hyponatremia due to adrenal gland insufficiency is treated with hormone injections. Source: The Gale Group. Gale Encyclopedia of Medicine, 3rd ed.
