Hypertension  High Blood Pressure

Affected Animals:  Cats of all ages can develop hypertension, although middle-aged and older cats are affected most frequently. As a rule, the most common diseases associated with hypertension in cats are kidney failure and hyperthyroidism, which also tend to occur more often in middle-aged and older cats.

Information and Overview:  Most cats with hypertension have an underlying illness responsible for its development; kidney disease and hyperthyroidism are the two most common diseases associated with high blood pressure in cats. In rare circumstances, primary hypertension — high blood pressure without an associated or underlying cause can occur. The diagnosis is made by measuring the blood pressure, and treatment is usually initiated if the elevation is severe or if symptoms due to the high blood pressure are present. The long-term outlook with treatment for high blood pressure has not yet been determined. However, with increased awareness of the condition and early identification of elevated blood pressure readings, serious consequences of hypertension may be prevented from developing.
