What Is Feline Hyperthyroidism?

Feline hyperthyroidism is the most common hormone-related issue in middle-aged and older cats, affecting about 10% of cats  over 10 years old. It’s caused by an overactive nodule on the thyroid gland(s), which releases too much thyroid hormone. Cats have two thyroid lobes, one on each side of their neck, and either or both can be affected. This extra hormone revs up their metabolism, leading to weight loss and putting strain on the heart, digestive system, and other organs.

 

If your vet diagnoses your cat with hyperthyroidism, it's important to start treatment to manage the symptoms. Without treatment, symptoms worsen, causing severe weight loss and potentially serious issues with the heart, kidneys, and other organs.
