Treatment for 21 hydroxylase deficiency focuses on hormone replacement and managing symptoms: - Glucocorticoids to replace cortisol. - Mineralocorticoids (like fludrocortisone) to manage aldosterone deficiency. - Salt supplements for those with salt-wasting forms of CAH. - Surgical correction for ambiguous genitalia if necessary. Regular follow-ups with an endocrinologist and a gynecologist are crucial to monitor and adjust treatment.
