Abstract
PRIMARY hyperaldosteronism (Conn's syndrome) is characterised by excessive autonomous secretion of aldosterone from one or both adrenal glands, resulting in clinical signs relating to hypertension and/or hypokalaemia. This disease was once considered uncommon in cats. However, several case reports and case series have recently been published, suggesting an increase in the frequency of diagnosis. This probably reflects heightened awareness of the disease together with more widespread availability of blood pressure measurement and ultrasound facilities. This article draws on experience to date to review the diagnosis and management of primary hyperaldosteronism. The disease should be considered an important differential diagnosis for both hypokalaemia and hypertension in cats.
