Hyperthyroidism in Cats

A common hormone condition in older cats, hyperthyroidism is very manageable with the right treatment and regular monitoring.

What is Hyperthyroidism?

Hyperthyroidism occurs when the thyroid gland becomes overactive, producing too much thyroid hormone. This speeds up the body's metabolism, leading to weight loss and other symptoms.

It's one of the most common hormone conditions in older cats (usually over 10 years old). With daily medication and regular blood tests to monitor thyroid levels, most cats do very well.

Signs & Symptoms

Hyperthyroidism can cause a range of symptoms. If your cat shows any of these, it's worth having them checked:

• Weight loss despite eating well
• Increased appetite
• Increased thirst and urination
• Restlessness or hyperactivity
• Poor coat condition
• Vomiting or diarrhoea
• Fast heart rate
• Behaviour changes

Testing & Diagnosis

Hyperthyroidism is diagnosed with a simple blood test measuring thyroid hormone levels. We also check kidney function, as hyperthyroidism can mask underlying kidney problems.
