5. Kidney Function Is Closely Linked to Potassium Regulation
The kidneys play a vital role in regulating potassium levels in the body. They are responsible for filtering excess potassium from the bloodstream and excreting it through urine. When kidney function is impaired, such as in chronic kidney disease (CKD), the body may struggle to maintain proper potassium levels. (6)
Individuals with CKD may experience an accumulation of potassium in their blood, leading to hyperkalemia. This can be dangerous, as it increases the risk of life-threatening heart complications. As a result, individuals with kidney issues must work closely with their healthcare provider to manage their potassium levels through dietary changes and, in some cases, medication adjustments.
On the other hand, acute kidney injury or other sudden changes in kidney function can lead to a drop in potassium levels, resulting in hypokalemia. In such situations, potassium supplementation or adjustments to medications may be necessary to restore potassium balance.
