What is the prevalence of diabetes insipidus?

Keywords: central diabetes insipidus, nephrogenic diabetes insipidus, gestational diabetes insipidus, dipsogenic diabetes insipidus, diabetes insipidus, antidiuretic hormone, vasopressin Introduction and background Diabetes insipidus (DI) is a rare disorder, affecting roughly 1 in 25,000 people or about 0.004% of the global population [1].

What is water deprivation test for diabetes insipidus?

Water deprivation test. If you have diabetes insipidus, you’ll continue to pass large amounts of dilute urine, when normally you’d only pass a small amount of concentrated urine. During the test, the amount of urine you produce will be measured. You may also need a blood test to assess the levels of antidiuretic hormone (ADH) in your blood.

What is the AVP test for diabetes insipidus?

Vasopressin test. After the water deprivation test, you may be given a small dose of AVP, usually as an injection. This will show how your body reacts to the hormone, which helps to identify the type of diabetes insipidus you have. If the dose of AVP stops you peeing urine, it’s likely your condition is the result of a shortage of AVP.
