Annual blood and urine tests are important in all cats seven years and older to detect hyperthyroidism before potentially irreversible damage occurs. However, an overactive thyroid is quite common. Surgery. If we restrict iodine, production of thyroxine decreases. If the disease involves both lobes of the thyroid gland, two surgeries may be required, depending on the surgeon's choice of procedures. The advantages of radioactive iodine therapy are that the procedure most often cures hyperthyroidism, has no serious side effects, and does not require anesthesia.

Usually this means that the cat will need to be hospitalized for between three and five days after treatment. In a study of 524 hyperthyroid cats treated with I-131, only 11/524 (2.1%) developed Employees of facilities that utilize radioactive materials may be categorized as "radiation workers" depending on their role. Hypertension, or high blood pressure, is another potential complication of hyperthyroidism, and can cause additional damage to several organs, including the eyes, kidneys, heart, and brain. Design and methods: Five hundred and four patients over 40 years of age with diffuse toxic goiter were treated with MMI for 18 months. The American Thyroid Association notes that weight gain develops over a long time and may have many causes other than the underactive thyroid.

The total effective dose equivalent to individual members of the public from the licensed operation does not exceed 1 mSv in a year, exclusive of the dose contributions from background radiation, from any administration the individual has received, from exposure to individuals administered radioactive material. Now the question is what risk does one obtain from receiving an exposure of 1 mSv? Is radioactive iodine treatment safe? This isnotan iodine-free diet but a diet with a controlled iodine content of 0.2ppma minimal amount. The 1-month level thyroid may be slightly high, low or normal. The average US total radiation exposure (all sources) is 6.2 mSv/yr which is an increase from 20 years ago (3.6 mSv/year) when CT scans were much less common. Radioactive iodine therapy.

Due to the damaging effects of hyperthyroid-induced hypertension on your cats kidneys, blood kidney values must be reassessed once the thyroxine level has normalized, even if they were normal on initial blood tests. It is best to perform a nuclear scan before surgery to rule out ectopic thyroid tissue. The three ways that we control exposures to external sources of radiation are time, distance, and shielding. You may gain weight after you undergo radioactive iodine treatment. The slow onset of signs means that cat owners will often miss these changes until the late stages of disease. Of 135 patients with documented pubertal status . When an injection of radioactive iodine is given, it destroys the abnormal thyroid tissue without endangering other organs.

Hyperthyroid cats are also at risk for complications related to the hypertension that frequently accompanies hyperthyroidism. A standard Chest x-ray is 0.1 mSv.
