The Myth of Primary Polydipsia

<p><span style=color: rgba(15 17 17 1)>'The diagnosis of compulsive water drinking must be made with care and may represent our ignorance of yet undescribed pathophysiological mechanisms.' - Prof. Daniel Bichet University of Montreal 2017.</span></p><p></p><p><strong style=color: rgba(0 0 0 1)>Primary Polydipsia is widely viewed as compulsive over-drinking without physiological cause often labelled psychogenic and linked to mental illness.
