Hyperthyroidism - disease and treatment
The thyroid glands are small organs found just under the skin, either side of the windpipe in the neck. These glands produce thyroid hormone which helps to regulate your cat's metabolism, or rate of bodily activity. Production of thyroid hormone is normally closely regulated in the body as the effects of too much (or too little) can be very serious. Hyperthyroidism is a disease caused by overactivity of these glands. When the thyroid gland produces too much hormone, your cat's 'internal motor' effectively goes into overdrive. Untreated this would eventually be fatal but the condition can be successfully treated.
