Hyperthyroidism is a common condition, often affecting older cats.
The thyroid gland is a small gland that sits within the neck; it is responsible for producing thyroid hormones which control our metabolism. With hyperthyroidism there is excessive production of these hormones which result in an increased metabolism. This means the body is burning through more energy.
This presents as weight loss in affected cats, despite having a ravenous appetite. Affected cats will often be quite restless, and possibly irritable and vocal. Affected cats may have increased thirst with subsequent increased urination also. Some cats may also develop vomiting or diarrhoea.
If left untreated hyperthyroidism will result in high blood pressure (known as hypertension) which can have detrimental effects on the body. It can also result in changes to the heart in some cases.
Hyperthyroidism is usually easily diagnosed by a blood test in which we measure the level of thyroid hormone in the blood. If this is increased above normal then the cat is diagnosed with hyperthyroidism.
There are secondary blood tests we can also perform if necessary to help achieve a diagnosis.
Because this is such a common disease of cats there are a variety of treatment options available.
So if you have noticed weight loss in your cat despite a seemingly normal or increased appetite, as well as restless behaviour, vomiting, or diarrhoea, then arrange an appointment with a vet and we can investigate.
