Do cats with hyperthyroidism have breathing problems?

Fast respiratory rate, panting, difficulty breathing In the absence of heart failure, weakness of the respiratory muscles due to chronic hyperthyroidism is the most probable reasons for these signs.

Is hyperthyroidism related to hypertension?

When the thyroid gland doesn’t produce enough thyroid hormone (hypothyroidism) or produces too much thyroid hormone (hyperthyroidism), high blood pressure can result.

Can hyperthyroidism cause a stroke?

AF and Cardioembolic Stroke. AF occurs frequently in patients with hyperthyroidism and may be the presenting symptom. Various studies suggest a prevalence of 10% to 15% in patients with hyperthyroidism, and it is more common in men than in women.

What are the side effects of hyperthyroidism in cats?

Two secondary complications of hyperthyroidism can be significant; hypertension (high blood pressure) and a particular form of heart disease called thyrotoxic cardiomyopathy. Hypertension develops due to the increased pumping pressure and elevated heart rate that occurs with thyrotoxic cardiomyopathy.

What happens when your cat’s blood pressure is too high?

Hypertension develops due to the increased pumping pressure and elevated heart rate that occurs with thyrotoxic cardiomyopathy. About 25% of cats with hyperthyroidism become hypertensive. In some cats, blood pressure can become so high that retinal bleeding or retinal detachment will occur, resulting in sudden blindness.

Is there such thing as secondary feline hypertension?

But in the great majority of cases, secondary feline hypertension is a consequence of kidney disease or, less often, hyperthyroidism or diabetes. There is no recognized predisposal for feline hypertension in terms of gender or breed, but an animal’s age does seem to be relevant. That is, the risk for hypertension rises as a cat grows older.
