3

Mineralocorticoid replacement

Fludrocortisone replacement maintains electrolyte balance and blood pressure in patients with aldosterone deficiency. Regular monitoring of electrolytes and renin levels guides dosing adjustments.

medication

Additional treatment options

Sodium supplementation

Increased dietary sodium intake helps compensate for mineralocorticoid deficiency and reduces the required fludrocortisone dose. Salt supplementation is particularly important in infants.

dietary

Regular endocrine and electrolyte monitoring

Scheduled laboratory monitoring of electrolytes, renin, and adrenal hormone levels ensures adequate replacement and prevents complications from over or under-treatment.

monitoring
