Diagnosis and tactics of managing a patient with central diabetes insipidus on the example of a clinical case

Diagnosis and differential diagnosis of patients with diabetes insipidus is often a difficult task for the endocrinologist. This case report focuses on a patient with a long history of central idiopathic diabetes insipidus who had a substantial decrease in desmopressin requirements during the last year of follow-up. Conducting tests with osmotic stimulation (test with water deprivation, infusion test with hypertonic solution) made it possible to answer the question of the persistence of the disease, as well as to determine a further management plan, taking into account the physiological characteristics of our patient.
