This video contains a detailed and simplified explanation about diabetes insipidus. We discuss the differences between cranial and nephrogenic diabetes insipidus, the signs and symptoms, testing for diabetes insipidus including an explanation of urine and blood osmolality and the water deprivation test (also known as the desmopressin stimulation test) and how we manage diabetes insipidus.

For medical advice see your doctor or other healthcare professional. Whilst significant effort has been taken to make the information accurate it cannot be guaranteed.
