Cortisone Therapy and Mineral Excretion

During prolonged or high-dose cortisone (glucocorticoid) therapy, several significant mineral and electrolyte imbalances occur in the body, leading to increased urinary excretion.

Key Minerals Lost in Urine

• Calcium: Cortisone significantly decreases intestinal calcium absorption while simultaneously increasing renal excretion of calcium in the urine, often leading to a negative calcium balance and an increased risk of bone density loss (osteoporosis).
• Potassium: Glucocorticoids promote the excretion of potassium by the kidneys, which can lead to hypokalemia (low blood potassium levels), potentially causing muscle weakness and fatigue.
• Magnesium: Increased renal clearance often accompanies corticosteroid use, leading to greater urinary losses of magnesium, which works closely with calcium and potassium in cellular metabolism.
• Zinc: Urinary excretion of zinc can also be elevated during chronic steroid use, impacting immune function and tissue repair.
• Sodium: Unlike the minerals above, sodium is typically retained rather than lost in the urine during cortisone therapy, which can lead to fluid retention, edema, and elevated blood pressure.

Nutritional Considerations

Nutritional Management

• Supplementation: Because of the pronounced loss of key minerals like calcium, potassium, and magnesium, targeted nutritional support is often critical during prolonged therapy.
• Monitoring: Regular assessment of electrolyte and mineral status is recommended to counteract deficiencies induced by pharmaceutical interventions.
