Electrolytes & Kidney Health are essential for filtering waste and excess fluid from the blood1 and helping regulate the balance of electrolytes in the body. Kidneys do this through four processes — filtration, reabsorption, secretion and regulation of acid-base balance and osmolality.
When kidney function declines due to chronic kidney disease (CKD), electrolyte levels may also decline. Kidney disease can cause a range of electrolyte imbalances including sodium, potassium, calcium, magnesium, chloride and bicarbonate. These electrolytes, found in the blood, tissues and urine, help regulate heart rhythms, control fluid levels, support nerve and muscle functions, move nutrients into cells and ward off diseases.
The Link Between Electrolytes & Kidney Health
Sodium (Na+) plays an important role in regulating blood pressure and is critical for fluid regulation. Imbalances in sodium levels, either too high (hypernatremia) or too low (hyponatremia), can strain kidney function and negatively affect overall health.
Potassium (K+) is critical for muscle function, especially the heart. Disruptions in potassium levels, whether too high (hyperkalemia) or too low (hypokalemia), can strain the heart and cause life-threatening abnormal electrical signals in the heart, called arrhythmias.
CKD can lead to electrolyte disturbances that are not always easy to detect and can be difficult to treat effectively. Regular monitoring, hydration and following a well-balanced diet is key to maintaining healthy electrolyte levels throughout the progression of CKD and dialysis.
