Hypertension in cats….

Hypertension, or high blood pressure, is a condition that affects 1 in 5 cats from 9 years of age. If left untreated, hypertension can lead to serious health problems, including damage to the eyes, brain, heart, and kidneys.

In this article, we'll take a closer look at hypertension in cats, it’s causes, symptoms, and treatment options.

Causes of Hypertension in Cats

There are several factors that can contribute to hypertension in cats, including:

  1. Kidney disease: Cats with chronic kidney disease are at a higher risk of developing hypertension.

  2. Hyperthyroidism: This is a common condition in older cats, and it can lead to hypertension. 

  3. Obesity: Cats that are overweight or obese are more likely to develop hypertension.

  4. Age: As cats age, they become more susceptible to hypertension.

Symptoms of Hypertension in Cats

Hypertension is often called the "silent killer" because cats may not show any symptoms until the condition has become severe. Some of the signs that might be seen:

  1. Hypertension can cause damage to the blood vessels in the back of the eye, leading to blindness.

  2. Seizures: Cats with hypertension may experience seizures.

  3. Behavior changes: Cats with hypertension may become disorientated, more irritable or lethargic.

  4. Increased thirst and urination: Hypertension can lead to kidney damage, which can cause cats to drink and urinate more than usual.

  5. Nosebleeds: Cats with hypertension may experience nosebleeds.

  6. Heart disease: Hypertension in cats can lead to thickening of the heart muscle and secondary heart problems.

If you notice any of these symptoms in your cat, it's important to make an appointment with one of our vets as soon as possible.

Diagnosing Hypertension in Cats

Hypertension is diagnosed by measuring your cat's blood pressure. This is done using a blood pressure monitor specifically designed for cats, using a cuff that is placed around the cat's leg or tail.

In some cases, additional testing may be necessary to determine the underlying cause of hypertension. This may include blood and urine tests to evaluate kidney function and thyroid hormone levels.
