Diabetes Insipidus (DI)

Diabetes Insipidus (DI) is a rare disorder that affects the kidneys' ability to conserve water, leading to excessive thirst (polydipsia) and urination (polyuria). Unlike Diabetes Mellitus, it is not related to blood sugar levels. DI occurs either because the body doesn't produce enough antidiuretic hormone (ADH), which helps regulate water balance (central DI), or because the kidneys don't respond properly to ADH (nephrogenic DI). If a pet with DI cannot access water, they can quickly become severely dehydrated, which is an emergency. Diagnosis involves specific tests to differentiate it from other causes of increased thirst and urination. Treatment often involves medication to replace or enhance the effect of ADH, alongside ensuring constant access to fresh water.
