Polydipsia and polyurea in two horses caused by psychogenic polydipsia

Polyuria‐polydipsia in the horse

“…Affected animals often eat their bedding or chew on doors, etc. This syndrome is described in detail in a case report by Browning (2000).…”

“…• Alteration of management system (including feed, bedding, routine), environment (turn-out, walker etc.) and exercise regimen (Brown 1997;Browning 2000). • Limitation in water intake through restriction over 2-4 days (Roussell et al 1987;Brown 1997;Browning 2000).…”

“…and exercise regimen (Brown 1997;Browning 2000). • Limitation in water intake through restriction over 2-4 days (Roussell et al 1987;Brown 1997;Browning 2000). • Electrolyte therapy: Sharp (1980) found that broad electrolyte replacement was effective in treating 5 cases of PU/PD.…”

“…It may be necessary to collect 12 or 24 h urine output and this itself is not an easy task requiring the use of purpose made collection devices that are sometimes not well tolerated. Browning (2000) reports on polyuria and polydipsia in 2 horses caused by psychogenic polydipsia. In this issue, a brief review of the physiology forming the background to the condition is described, together with the diagnostic and differential diagnostic approaches.…”

Clinical Approach to Commonly Encountered Problems

“…642,653 The behavior has also been associated with changes in environmental conditions, stabling, and diet. The extent of polydipsia and therefore polyuria seen with psychogenic water drinking can be substantial.…”
