What causes high Sodium and low Potassium?

High Sodium and low Potassium can be caused by many reasons.

If your Sodium is in between 136 mmol/L and 145 mmol/L and your Potassium is in between 3.5 mmol/L and 5.1 mmol/L then you need not worry as these are the normal ranges for Sodium and Potassium respectively. But if your levels are lesser or greater than the above values, then there may be some problem in your body.

Normal range of Sodium : 136 - 145 mmol/L

High Sodium and low Potassium can be caused by a lot of reasons.
