One of the most common diseases in middle-aged and older cats is hyperthyroidism. An increase in the production of thyroid hormones, i.e., T4 and T3, is the primary cause of this disorder. The enlarged thyroid gland in the neck region of the cat is the most common visible sign identifying hyperthyroidism. This enlargement is a non-cancerous tumor known as an adenoma. However, in some rare cases, it can also be caused by malignant tumors known as thyroid adenocarcinomas. Hyperthyroidism increases the metabolic rate in an animal's body because of high circulating thyroid hormone and often causes secondary problems by affecting all body organs.
The reason for feline hyperthyroidism is unfamiliar. However, deficiencies or excesses of some elements in the diet and thyroid-disrupting could be responsible for the onset of hyperthyroidism. Hyperthyroidism is rare in dogs. However, if it occurs, it is primarily because of thyroid carcinoma. This contrasts with the case in hyperthyroid cats, where less than 5% of thyroid tumor is carcinoma. Therefore, early diagnosis with appropriate treatment is necessary to avoid complications.
In this webinar, different diagnoses for feline hyperthyroidism will be discussed that are currently being used in veterinary practices and animal hospitals. The advantages and disadvantages of various treatment methods will also be addressed. Overall, it will provide insight into the severity, accurate diagnosis, and better cure of this disease.
