In this lecture, Professor Zach Murphy will present on Diabetes Insipidus (DI) and the Syndrome of Inappropriate Antidiuretic Hormone secretion (SIADH). We will discuss the pathophysiology of DI, which involves a deficiency of antidiuretic hormone (ADH) leading to excessive urine production, and SIADH, which involves excessive ADH leading to water retention and hyponatremia. The lecture will include a discussion on the clinical manifestations of DI, such as polyuria and polydipsia, and SIADH, such as fluid overload without edema and dilutional hyponatremia. The digital presentation will begin with the diagnostic approach, highlighting the importance of water deprivation tests for DI, serum, and urine osmolality measurements, and serum sodium levels. Finally, we will review management strategies for both conditions, emphasizing fluid intake adjustments and desmopressin for DI, and fluid restriction, salt tablets, or medications to block ADH effects in SIADH.
