Hyperthyroidism in Cats Life Expectancy

Wondering what is hyperthyroidism in cats life expectancy? Hyperthyroidism may sound like a subtle disease, but this particular thyroid-related disease can be menacing to our furry fellow. Given that this can be a serious concern, it is even said that it may reduce one’s life expectancy quite a lot. What is the exact number? It depends.

Before digging deeper to know how hyperthyroidism affects cats and what it takes, we first need to know what the disease means and what the symptoms are.


Hyperthyroidism in cats is defined as a disease in which the feline thyroid gland overworks and produces a bigger number of thyroid hormones. It is known that this hormone has its vital function in the body, but if the body has too much hormone, then it may affect bodily physiologic function, such as heart rate, kidney function, and many other else.



Hyperthyroidism in cats is pretty difficult to diagnose as the symptoms can be quite subtle, such as instant weight loss, better hunger, and tachycardia (rapid heart rate) – all of which are pretty normal for senior cats more than 10 years old to have.

Aside from that, behavioral changes like increased agility, active meowing, restlessness and hyperactivity, notable increase of appetite and thirst (despite the rapid weight loss) are usually reported as well. Greasy coat, frequent vomiting and/or diarrhea are other rarer symptoms that may develop as well.



The diagnosis for hyperthyroidism is usually made by performing bloodwork panel (usually specific to checking T4 hormone) in senior cats. It is essential to know that the disease is not limited to only senior cats, so it becomes a top-notch thing to consider that younger cats also get a routine checkup.

The first thing that may ring the alarm is the consistent high blood pressure, combined with the record of previous data. Excessive weight loss can also be diagnosed according to the data obtained from the previous vet visit.



So, what’s the hyperthyroidism in cats life expectancy? Well, although some may say it is dangerous, luckily this disease is a manageable one. This will be more manageable if your cat is diagnosed and treated in earlier stage of the disease. Things go bad when the disease is not treated well – and it takes a toll to your feline’s life expectancy.

To mention the specific number of years, it is quite difficult to do. Some may go to 3-5 years before the disease gets worse, some may even survive for just months after the cure. It also depends on how the disease is managed.

To manage this disease, one can deal with the disease through dietary control, in-situ surgery, and radioactive treatment. While it is said that radioactive treatment is the best one, each method has different role in dealing with hyperthyroidism in cats life expectancy.
