In cats, high blood pressure, known as hypertension, is often caused by another underlying disease. For example, cats suffering from kidney disease or hyperthyroidism often have some degree of hypertension as well. It can also occur as a primary condition.
The organs most vulnerable to the effects of high blood pressure are the eyes, kidneys, heart and brain. Initially, there may be very few signs of high blood pressure, particularly if it is the primary problem. Sometimes the signs appear very suddenly.
Signs of hypertension include:
- changes inside the eye, including bleeding
Many cats go on to lead relatively normal lives following diagnosis and stabilisation of hypertension, but this depends on the type and severity of any underlying disease. If left untreated, these signs can become permanent, so talk to your vet as soon as possible.
