I’ve said partly in jest for many years that if I were an older cat and if I had to pick a disease to be afflicted with, I would choose hyperthyroidism. The exact cause of this condition remains unknown, but its primary feature is a benign enlargement of the paired thyroid glands which lie at the midpoint of the underside of the neck of all cats.
The enlarged glands produce excessive levels of thyroid hormone which is simply thought of as the bodies thermostat. High levels can cause a constellation of signs such as excessive vocalization, weight loss despite a ravenous appetite, increased frequency of vomiting, heart murmurs and secondary heart disease, and changes in liver enzymes which are often noted on biochemical tests. Without treatment, cats will often gradually deteriorate and may suffer several different serious consequences such as acute blindness and liver or heart disease. Treatment options for years were well established. Daily administration of a medication called methimazole would often suffice to control the hormone levels. Surgical removal of one or both affected glands would also be considered an option, and finally, intravenous injections of radioactive iodine was considered the gold standard of treatment. Recently Hills has introduced another option to consider. Prescription diet Y/D was introduced recently as an additional means to control this very common disease. Tightly controlled levels of iodine in Y/D allow cats with hyperthyroidism to eventually maintain normal levels of thyroid hormone and live without the need for daily pilling, surgery or costly radiation therapy. Anyone who has tried to administer oral medication to an angry cat can attest to the potential benefit of such a diet. Follow the link below to learn more about this innovative new diet!
