Nephrogenic diabetes insipidus is treated with thiazide diuretics. The usefulness of thiazide diuretics in treating nephrogenic diabetes insipidus is explained as follows:
a. Thiazide diuretics inhibit Na+ reabsorption in the early distal tubule. By preventing dilution of the urine at that site, the final, excreted urine is less dilute.
b. Thiazide diuretics decrease glomerular filtration rate; because less water is filtered, less water is excreted.
c. Thiazide diuretics, by increasing Na+ excretion, can cause a secondary ECF volume contraction.
