Feline Hyperthyroid Trmt

As a veterinary team, we are dedicated to both our patients and their owners.  We strive to be as thorough as possible for only your cat's medical care but also to ensure that you are fully informed of the options available to you as a pet owner.  We are proud to offer Radioactive Iodine or I-131 Therapy for the treatment of Feline Hyperthyroidism.  It is considered to be the "gold standard" of the available treatments.  The other forms of treatment include daily medication administration, surgical removal of the affected tissue and nutritional management (Hill's Prescription Diet Y/D).  Each of the treatments have their pros and cons, but radioactive iodine therapy is considered the preferred method of treament in most cases in terms of both effectiveness and overall safety.

Feline Hyperthyroidism is a disease of the endocrine system.  It is the most common endocrine disorder that affects cats and one of the most common disease of middle-aged and senior cats.  It is caused when the thyroid gland produces excess amount of the thyroid hormones.  This excess production is found in tumor-like cells on the thyroid.  Ninety-eight to ninety-nine percent of these are benign tumors, with only 1-2% of the cases being cancerous.  Hyperthyroidism typically appears in cats 9-13 years of age.

The thyroid gland virtually affects every system in the body, therefore symptoms can be wide-ranging. Cats may demonstrate: weight loss, increased appetite, changes in hair coat (alopecia, excessive grooming behavior), vomiting, diarrhea, increased activity or restlessness, increased thirst and urination, panting or respiratory distress, heat intolerance, stress intolerance, increased heart rate and/or heart murmur, increased blood pressure and occasionally, depression or weakness may be observed. Hyperthyroidism is diagnosed with a physical examination, including a thorough history and blood testing.

Radioactive Iodine or I-131 Therapy is typically a one-time treatment that is sufficient to normalize thyroid function in 98% of cases.  This highly effective treatment utilizes radioactive iodine to selectively destroy the malfunctioning thyroid tissues.  Healthy thyroid tissues are not affected by the treatment.  It si considered the safest method of treatment and cats usually have normal thyroid function within 4-6 weeks following radioactive iodine therapy.  This treatment is cost effective over time versus daily medication regimins and save cat owners from having to administer medications 1-2 times per day for the lifetime of their cat.

Our team of doctors and veterinary technicians have undergone special training in bothe care care of the hyperthyroid patient and how to safely manage the rradioactive materials utilized in the treatment of feline hyperthyroidism.  We are committed to helping cats lead normal, healthy lives!  We are dedicated and here to help you.  If you have any questions, or would like further information, please inquire with a member of our front desk team.
