Dietary Changes
Dietary changes may need to be made, such as:

- Limiting fluids if sodium levels are too low
- Avoiding alcohol, which can impair liver function
Medicine
Diuretic medicines cause the kidneys to pass more sodium and water in urine. They may be used with a low sodium diet.

People who are not helped by these methods may need:
