Kidney Korner: Electrolytes- Sodium

How Dr. Munjal Helps:
Dr. Munjal can make dietary change recommendations, order Basic or Comprehensive Metabolic Panels (BMP/CMP) to check electrolyte levels, or order various supplements or infusions. 

Munjal’s Musings:
Sodium can come from a variety of sources, salt being one of them. One of the other most common sources of sodium is food preservatives. While it may be tasteless and not “salty,” it does not mean that it does not have sodium. A low sodium diet is generally recommended for patients with high blood pressure and kidney diseases. 

If you have any concerns or questions regarding sodium, please contact your Primary Care Physician or Nephrologist for recommendations. As always, stay safe and healthy!
