In cats, high blood pressure often occurs as a concomitant symptom of another underlying disease, such as kidney failure or an overactive thyroid (hyperthyroidism). At the same time, high blood pressure can make these and other diseases worse. It is therefore advisable to reduce it back to a healthy value as early as possible.

Hypertension in cats: treat cause

If it is not so-called primary hypertension, then a certain underlying disease is the cause of the increased blood pressure values. If this disease is treated successfully, the blood pressure usually normalizes again. Treatment of renal failure or therapy for hyperthyroidism in cats also benefits from lowering blood pressure.

For some diseases that cause high blood pressure, a diet can also be useful. For example, diabetes can be alleviated by reducing weight and kidney problems can be alleviated by reducing the phosphorus and protein levels. High blood pressure can be particularly dangerous for cats with heart problems like HCM. In this case, a low sodium diet can help with the symptoms. However, do not under any circumstances feed diet food without first speaking to your veterinarian. Much else can go wrong with cat nutrition, so professional advice on changing your diet is essential.

Lower high blood pressure with tablets

There are also medications that help lower high blood pressure. Tablets with the active ingredient amlodipine are used to treat high blood pressure in humans, but can also be used for affected cats. Your veterinarian will determine the appropriate dose after a thorough examination.

The agent is a so-called calcium channel blocker. The cells of the muscles in the blood vessels absorb less calcium ions, so the calcium concentration in the blood drops. As a result, the vascular muscles can no longer contract so tightly and the vessels widen. The blood can flow through easier again and the blood pressure drops.
