Diabetes insipidus (DI) is a disorder of the posterior pituitary gland characterized by insufficient secretion of antidiuretic hormone (ADH), resulting in excessive urine output and dehydration. The primary electrolyte imbalance in DI is hypernatremia (elevated serum sodium levels) due to the loss of free water in urine. The other options (hyperglycemia, hypercalcemia, and hypoglycemia) are not typically associated with DI.
