How do kidneys process sodium and potassium?

Your kidneys are daily engaged in the necessary filtration of sodium and potassium. They continuously adjust the amount excreted to maintain a proper balance of sodium and potassium in the blood. Healthy kidneys filter approximately 180 liters of fluid daily, retaining valuable mineral elements. This complex process is a vital means of maintaining the body's balance.

Kidney disease affects this fine filtration system. Impaired nephrons cannot adequately excrete the excessive potassium. Sodium retention leads to fluid retention and swelling. This dual disturbance increases the risk of cardiac complications and morbidity requiring urgent medical attention.

Drugs significantly impact the kidney's ability to process. For example, ACE inhibitors will decrease potassium excretion. Diuretics, on the other hand, will increase sodium excretion. Both drugs would require dose adjustment and monitoring. There have also been patients, whom I had to adjust medications at least once a month whenever their renal function worsened.

Patients with kidney disease need to be under close medical supervision. Routine blood work is performed to monitor electrolyte levels. Sodium intake from diet should be limited to <2,000mg/day. Patients may need to restrict potassium intake to <2,000mg daily or as directed. Limiting sodium and potassium allows the healthcare team to avoid dangerous mineral concentrations in the patient.

Enhance the health of your kidneys by drinking plenty of fluids and maintaining a balanced diet. Drink at least eight glasses (8 oz each) of water every day. Limit your intake of processed foods high in sodium. Choose moderate potassium-rich foods, such as apples and berries. All of these practices will help minimize the strain of filtration, allowing you to maintain your kidney function.
