Question

Quizplus · Accepted Answer

The patient's symptoms of polyuria and extreme thirst are indicative of diabetes insipidus (DI). When exogenous ADH is given, it can be effective in treating neurogenic DI, which is caused by a deficiency or lack of production of ADH in the hypothalamus or pituitary gland. Psychogenic DI is caused by excessive water intake and is not treated with exogenous ADH. Nephrogenic DI is caused by a failure of the kidneys to respond to ADH and is not typically treated with exogenous ADH. Syndrome of inappropriate antidiuretic hormone (SIADH) is a condition in which the body produces too much ADH and results in water retention, rather than loss of water. Treatment for SIADH typically involves treating the underlying cause and restricting fluids.
