Cats - Hyperthyroidism

  • The thyroid is  a two lobed gland with one gland located on each side of the windpipe (trachea) in the neck area. The thryoid gland produces thyroid hormone which is released into the blood stream and act on cell in the body. This hormone controls the rate at which every cell in the body functions. Too much thyoid hormone causes every cell to work too fast (Hyperthyroidism)
  • The common signs that we can see are Increase in apetite but they still lose weight. Patchy hair loss,  increased thirst and urination, hyperexcitability, vomiting or diarrhoea. Some animals may present with difficulty breathing or are extremely lethargic. Almost all cats diagnosed with this disease are over the age of eight.
  • Sometimes the cause of the hyperthyroidism is a benign tumour, but we don't always not what causes this disease.
  • To diagnose this disease we need to run a blood test to show us the levels of thyroid hormone.
  • Treatment
  • There are three main treatments: 
  •  This is often a twice daily medication, either an oral tablet or a cream that is placed on the inside of the ear. The cats need to be regularly monitored to make sure the amount of thyroid hormone they are producing is not too high or too low
  • if they have a mass that can be felt, it is possible to surgically remove this tumour. Some animals will no longer require long term treatment after this procedure.
  • this is a procedure performed at some specialist clinics where they inject a radioactive iodine substance into the blood stream which will kill abnormal thyroid cells.
