Thyroid troubles

Thursday, August 09, 2018

Is your old cat ravenous - but losing weight no matter what you feed him? Often this is the first sign of an overactive thyroid gland. Many hyperthyroid cats are also more tetchy, demanding or restless than when they were younger. Observant carers might notice occasional vomiting or toileting outside the litter box. Some cats pant or don't look after their coats very well. Hyperthyroidism makes all body systems work harder including the heart, kidneys and bowels.

While all these signs individually might be put down to old age any one or more of them make our vets very suspicious of a thyroid nodule producing too much thyroxine - hyperthyroidism. Too much thyroxine accelerates aging and puts a strain on all the body's organs.

A capsule of Radioactive Iodine (RAI) in an otherwise healthy cat cures hyperthyroidism. To check if your cat is a candidate for RAI blood and urine is collected to confirm hyperthyroidism and check kidneys, liver and other organs.

If your cat has other problems like kidney disease then daily medication as a tablet or transdermal gel is easy and convenient.
