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.

How does hyperadrenocorticism cause PU PD?

All causes of PU/PD that result in anti-diuretic hormone (ADH) resistance, not just primary diabetes insipidus, can lower the urine specific gravity to hyposthenuric values (<1.008). In particular, a significant proportion of dogs with hyperadrenocorticism have hyposthenuric urine.

What can cause PU PD in dogs?

In dogs some of the most common conditions that cause PU/PD are Hyperadrenocorticism (commonly called Cushing’s disease), diabetes mellitus, and kidney diseases of which there are multiple forms. In cats, some of the most common causes are diabetes mellitus, hyperthyroidism, and kidney diseases.

What are the 3 P’s of hyperglycemia?

How serious is polyuria?

Polyuria can be treated and, in the short term, is not dangerous. However, it’s crucial to get it corrected so that any potential underlying condition doesn’t go untreated.

What is polydipsia a symptom of?

Polydipsia is the term given to excessive thirst and is one of the initial symptoms of diabetes. It is also usually accompanied by temporary or prolonged dryness of the mouth.

Why does liver disease cause PU PD?

Liver disease: PU/PD may occur as the result of: (1) decreased production of urea which is a major component of the hypertonic medullary interstitium, (2) increased renin and cortisol levels due to a lack of hepatic degradation, (3) increased aldosterone concentration leading to increased sodium concentration, and (4) …

How does liver disease cause polyuria?

Polyuria can often be an early sign of kidney trouble. Liver disease. Problems with your liver can also affect your kidneys. Your liver can’t process waste like it should, and liver damage reduces the blood flow to your kidneys so they can’t do their job.

What causes polyuria in central diabetes insipidus?

How to test for polyuria and polydipsia?

Test concluded with either a 5% loss in body weight, azotemia (BUN > 30), or urine specific gravity > 1.030 (1.035 cats). The bladder is emptied, and urine is saved for specific gravity and osmolality, and plasma is obtained for osmolality.

How are uccrs used to diagnose hyperadrenocorticism?

After analysis of the first two UCCRs have shown elevation in urine cortisol to confirm the diagnosis of hyperadrenocorticism, the two samples can be combined into a single “pre” or baseline sample.
