Hyperthyroidism is the most common endocrine disorder in the cat. Since being first recognized in 1977, the incidence has increased steadily. This is, no doubt partly due to greater awareness and early screening, but certainly also due to a real increase in occurrence of this disease.
The pituitary gland is a small structure that adheres to the base of the diencephalons; just caudal to the optic chiasm. It is comprised of an anterior portion-the adenohypophysis(which is made up of the pars distalis and the pars intermedia) and a posterior portion termed the neurohypophysis (pars nervosa).
Management of the uncomplicated feline diabetic can occasionally be controlled by oral hypoglycemic agents (approximately 25-35%). This is because approximately 90% of the feline diabetic patients are similar to human Type2 diabetes mellitus (non-insulin dependent diabetes mellitus-NIDDM). However, by the time the cat is diagnosed with diabetes mellitus, the blood glucose is severely elevated (often>450 mg/dl) and many cats are ketotic, thus insulin is usually required.
The thyroid gland is made up of paired lobes on the ventrolateral surface of the proximal trachea. Felines may have accessory thyroid tissue in the neck and thorax. The size of the thyroid gland varies with the size of the dog; with medium-sized dogs having lobes approximately 5 cm. in length, 1.5 cm. in width, and 0.5 cm in thickness. In the average (4.5 kg) cat each lobe is approximately 2 cm.
