Treatment  

Fluid Replacement  

To regain a proper balance of fluids in your body, liquid can be given to you either by mouth or through an IV (needle in your vein). The fluid will contain a specific concentration of water, sugar, and sodium. Reintroducing fluids slowly into your body will lower the sodium to a normal level. Talk with your doctor about the best treatment plan for you.
