What is hyperthyroidism in cats?

Hyperthyroidism is a common thyroid gland disorder that leads to the overproduction of the thyroid hormone from thyroid glands that are located in the cat’s neck. Hyperthyroidism is a common disease for those cats that are 12 years old and higher.

The thyroid hormone is responsible for healthy metabolism, proper kidney function, and circulation of blood, so hyperthyroidism is an alarming signal. A significant increase in the secretion of thyroid hormone not only potentially affects the eyes, kidneys, brain, etc. but also plays havoc with the cat’s heart. An added bonus, a hyperthyroid cat will lose energy by leaps and bounds that result in weight loss despite your feline friend’s food intake has increased significantly.

What are the causes of hyperthyroidism?

It’s an open secret that cats have two thyroid glands in their neck and they are equally responsible for maintaining a healthy metabolism of cats. When any of the two thyroid glands becomes enlarged and there’s an increase of thyroid hormone, this leads to hyperthyroidism in cats.

Luckily, if hyperthyroidism is diagnosed at an early stage and the cat undergoes proper treatment, then the chances are higher that they can lead a healthy life where they can thrive.

7 Clinical signs and symptoms of hyperthyroidism in cats

No matter what is the sex of the cat, be it a male or a female, hyperthyroidism is a common thyroid gland disorder that affects the cat, when your feline friend has celebrated his/her 12th birthday. Studies also reveal that only 5 % of cats that haven’t celebrated their 10th birthday have been diagnosed with hyperthyroidism. Though the symptoms are usually subtle in the initial days but they play havoc over time as the secretion of thyroid hormone increases by leaps and bounds. Thyroid gland disorder predisposes and in the worst scenario mimics other diseases making it a tuff call to pinpoint the diagnosis of hyperthyroidism in cats.

Let’s take a glance at the 7 clinical signs and symptoms of hyperthyroidism in cats:

  • Despite the diet intake surge, it loses weight by leaps and bounds.
  • Steep rise in thirst and in turn frequent urination especially outside the litter box.
  • Frequent vomiting in no time after your feline friend finishes the meal.
  • Incessant belligerent behavior.
  • Breathing issues.
  • Heartbeat on the double.
  • Depression.

How to diagnose hyperthyroidism in cats?

If you have found that your cat experiences frequent vomiting or a sharp rise in thirst and in turn increases the water intake, or loses weight by leaps and bounds, then you must refer to a vet ASAP.

Initially, vets carry out a physical examination and do proper screening whether there’s an enlarged thyroid gland or not. But there are various instances where there’s no enlargement of thyroid glands is visible. If the vet suspects that your feline friend has hyperthyroidism, then the chances are higher that your vet will examine not only the heart rate but also the blood pressure.

To confirm if your cat is suffering from hyperthyroidism, your vet is most likely to perform a blood test, because a blood test is a sure-shot method to check the levels of thyroid hormones in your feline friend’s blood. A majority of the cats who are suffering from hyperthyroidism have an elevated thyroid hormone level that rule out all the speculations.

How to treat a cat with hyperthyroidism?

When your vet has diagnosed successfully a hypothyroid cat at an early stage, there are 4 widely accepted treatment options available. Consult your vet and he will recommend the best plausible option among Medication, Radioactive Iodine Therapy, Surgery, and Dietary Therapy since every treatment option has its own pros and cons.

Medication

Medication is a life-long process where you employ anti-thyroid drugs namely methimazole to cap the secretion of thyroxine from the thyroid gland. Though this is not the best plausible option, yet these anti-thyroid pills up to snuff to put a stop to the oversecretion of thyroid hormone.

On the positive side, you will find the anti-thyroid drugs in your local shop, and they don’t require you to break the bank.

On the downside, irrespective of you are feeding the tablet twice a day, or apply a gel to the skin, there are various instances where a feline experiences vomiting, poor appetite, anemia, lethargy, etc.

Radioactive Iodine Therapy

This is one of the best plausible options you have got to bring your cat pre-hyperthyroidism state, but that demands to break the bank.

Radioactive Iodine Therapy involves a shot that is equipped with radioactive iodine. Later, the radioactive iodine is taken up by the thyroid. Iodine is responsible for the secretion of thyroxin and the radioactive iodine plays havoc with abnormal thyroid tissues without affecting not only the nearby tissues but also parathyroid glands.

The good news is that once your feline friend undergoes radioactive iodine therapy, the chances are higher that this iodine therapy drops the over secretion of thyroxine significantly and brings it to the normal levels between one and two weeks.

On the downside, though radioactive iodine therapy demands neither anesthesia nor daily medication, radioactive iodine therapy’s cost can lead you to break the bank. As your feline friend occupies a seat in the hospital for a period between one and two weeks until the radioactive radiation level is safe as per the federal administration, this can cost you an arm and a leg.

Surgery

When your cat doesn’t have cardiovascular issues and is healthy then the removal of the affected thyroid gland is the best plausible option. On successful completion, your feline friend is free from experiencing thyroid issues forever that don’t require meditation that can result in various side effects.

This surgery is associated with some inherent risks too. Maybe the parathyroid glands are unintentionally damaged while surgery. Parathyroid gland is in an adjacent position to the thyroid glands which are responsible for maintaining a stable blood calcium level. Plus, since the cat needs to undergo anesthesia, it possess a higher risk for not only the older cats but also cats with cardiovascular or kidney issues.

Dietary Therapy

Certain studies suggest that you should offer such food supplements with capped iodine content as the viable solution of hyperthyroidism. This is not a guaranteed solution. The chances are higher if you are offering an iodine-deficient diet in the long run then this may be a backfire and worsen the condition. Before shifting to an iodine-restricted diet, seek your vet’s advice.

What is the life expectancy of a cat with hyperthyroidism?

When untreated, a cat suffering from hyperthyroidism is likely to live a short span of life and will die of either cardiovascular issues or kidney failure. But if your vet has successfully detected a hyperthyroid cat at an early stage, then your feline friend can live a healthy and active life for a few years to come.

Though the success rate of the treatments that are applied to a hyperthyroid cat is great, life expectancy can’t be assumed on the dot.

How expensive is it to treat hyperthyroidism in cats?

Radioactive iodine therapy is the best option to get rid of hyperthyroidism, but is a little bit costly. The cost of radioactive iodine therapy varies between $1500 and $1600 including the hospitalization charges, food charges, etc. On the contrary, if you opt for the medication then this will toll between $400 and $500 every year. So, it’s a better idea to let your feline friend undergo radioactive iodine therapy since this is the most cost-effective option you have got.

What to feed a cat with hyperthyroidism?

When your cat is diagnosed with hyperthyroidism, it’s as clear as a day that there’s oversecretion of thyroid hormones from either of the thyroid glands. That results in increased thirst, frequent urination, and loss of muscle mass.

As a pet parent, it’s your task to feed the veterinary-prescribed cat food to put a stop to the loss of muscle mass and let your feline friend thrive after proper treatment.

If you are hunting high and low for the best cat food for cats with hyperthyroidism that will put a stop to weight loss and muscle loss, do consider the following questions and try to find the relevant answers.

Does the cat food contain only high-quality natural ingredients?

As a pet parent, your primary goal while picking the cat diet is to find quality supplements that don’t include artificial color or preservatives.

Is it a rich source of protein?

When you are on a witch hunt for healthy supplements that can put a stop to muscle loss or weight loss, then offer your feline friend a protein-rich diet that strengthens not only the lean muscles but also building blocks from muscles to the heart. As a good rule of thumb, offer your feline friend that wet cat food that will provide 50% of the calories from protein to boost healthy metabolism.

What percentage of carbs is there in the canned cat food?

When the cat’s food contains a lower percentage of carbohydrates, this will keep diabetes at bay since a higher-carb diet not only boosts blood glucose level but also shrinks glucose tolerance.  Wheat, corn, soy etc. impact the hormone secretion to a larger extend, don’t offer a canned cat food that exceeds the 10% carbohydrate content.

Does the cat food have high moisture?

With hyperthyroidism, a cat experiences excessive thirst and frequent urination. Offer your furry friend wet cat food that has higher moisture level of 85% and more.

Does the wet cat food have low-iodine?

An iodine-rich diet stirs the production of thyroid hormone. But if you are offering an iodine-deficient wet cat food, it will prevent the thyroid glands from the secretion of thyroxine.

The escape plan?

Offer the feline the therapeutic diet exclusively without offering such wet foods that have traces of iodine.

Is it Soy-free?

There’s a direct connection between soy consumption and secretion of thyroxine from thyroid glands. So, it’s a good decision to avoid canned cat foods that contain soy. There is no evidence that a soy-deficient diet hurts any cat.

Is it BPA-free?

Since bisphenol causes toxicity, it’s a good idea to feed a cat that is leveled as BPA-free.

An added bonus, when your ultimate goal is to bring your cat to the pre-hyperthyroidism stage, along with providing healthy supplements to your feline friend, take the following preventive measures:

  • Don’t offer them foods that contain soy, wheat, artificial color, or preservatives.
  • Avoid offering canned food that has ingredients including fish.
  • Don’t offer canned food or water in plastic bowls. Instead replace the plastic bowl with a bowl that is made of ceramic or stainless steel.
  • Don’t store healthy supplements in plastic containers.
  • Give a wide berth to canned foods without a BPA tag.
  • Escape from offering canned cat food the iodine content of which is incredibly high or incredibly low.
