Primary disorders of water balance (central diabetes insipidus, congenital nephrogenic diabetes insipidus, and psychogenic polydipsia) should always be considered in the differential diagnosis of polyuria and polydipsia. In general, animals with these disorders have only one laboratory abnormality, a low urine specific gravity. The more common causes of polyuria and polydipsia (eg, hypercalcemia, chronic renal insufficiency, pyelonephritis, hyperadrenocorticism), in most instances, have specific and obvious abnormalities associated with the complete blood count (CBC), serum chemistry profile, and urinalysis. However, in some cases, a low urine specific gravity may initially be the only abnormality in these more common ruleouts. The workup for polyuria and polydipsia, especially in those cases with normal or near normal blood work, can be tedious, time consuming, confusing, and not without significant patient morbidity. This chapter will focus on the problems associated with diagnostic testing used to evaluate animals with disorders of water balance.

Many animals with diabetes mellitus are severely ill on clinical presentation. The spectrum of disease is quite variable and includes diabetic ketoacidosis (DKA), ketosis without acidosis, hyperosmolar nonketotic syndrome (HNKS), and other nonketotic variants (negative urine ketones, serum osmolality < 340 mOsm/kg with or without acidosis). These more severe forms of diabetes are often precipitated by concurrent diseases such as pyelonephritis, pancreatitis, pyometra, hyperadrenocorticism, renal failure, and heart failure. To make matters worse, in-hospital treatment of diabetic dogs and cats is commonly associated with serious complications, including hypoglycemia, hypokalemia, and hypophosphatemia.

Primary disorders of water balance (central diabetes insipidus [DI], nephrogenic DI, and psychogenic polydipsia) should always be considered in the differential diagnosis of polyuria and polydipsia. In general, animals with these disorders have only one laboratory abnormality: a low urine specific gravity. In most instances, the more common causes of polyuria and polydipsia (e.g., hyperadrenocorticism, chronic renal failure, pyelonephritis, pyometra) have specific and obvious abnormalities associated with the complete blood cell count, the serum chemistry profile, and urinalysis. In some cases, however, a low urine specific gravity may be the only abnormality associated with these more common findings. The workup for polyuria and polydipsia can be tedious, time-consuming, expensive, confusing, and not without significant patient morbidity, especially in those cases with normal or near-normal blood work. This article focuses on the diagnostic approach and problems associated with diagnostic testing in patients with disorders of water balance.
