Case 13

Olivia's owner phones you two days later to let you know that Olivia is drinking 1.2 L of water a day. Given her weight, her water consumption should not exceed 680 ml in a 24-hour period, so she is clearly polydipsic. It is also likely that her urinary accidents may be related to polyuria as well.

QUESTION 2

Given Olivia's age and presenting clinical signs, which group of differential diagnoses would most likely explain the polyuria/polydipsia (PU/PD?)

a) Hyperadrenocorticism, renal failure, neoplasia

b) Liver disease, urinary tract infection, hypoadrenocorticism

c) Iatrogenic cause, diabetes mellitus, pyometra

d) Dietary change, postobstructive diuresis
