Last week I composed about Hypothyroidism in Dogs; this week I will go over one more crucial topic that likewise seems to cause much confusion. Hyperthyroidism is a condition mainly seen in cats as well as it is treated with a totally different set of medications. It is very crucial to understand the difference between these two conditions as well as which medication treats which condition. I will once again begin with a few fundamental definitions as well as likewise attempt to keep things as visual as well as remove as possible:

T3

T4
Thyroxine, created by the thyroid gland as well as together with T3 regulates lots of crucial body functions such as metabolism
The thyroid gland has the function of converting iodine into thyroxine (T4) as well as triiodothyronine (T3). The T4 as well as T3 circulate throughout the body as well as impact nearly every single organ. Thyroxine regulates growth, metabolism, immune function as well as heart function. Thyroid stimulating hormone (TSH) from the pituitary gland is what signals the thyroid gland to secrete thyroxine. Hyperthyroidism is the most typical endocrine condition diagnosed in cats. It normally occurs since of a tumor of the thyroid gland that ends up boosting the secretion of the thyroid hormones.

The veterinarian may do a total blood count (CBC), run a serum biochemistry to spot for possible existence of boosted liver enzymes, a baseline T4 test to get an quote of the thyroid levels, as well as something called a T3 Suppression test. In the T3 Suppression test, T3 is administered as well as if it triggers a decrease in T4 then the feline is normal; if the feline has hyperthyroidism then administering T3 will cause no decrease or a minor decrease in T4. The veterinarian may likewise want to do a scan of the thyroid gland to get a much better concept of what is going on.
Treatment
The goal of treatment is to lower as well as normalize circulating levels of thyroid hormone. There are three treatment choices offered for hyperthyroidism in cats:
Drug Therapy: The antithyroid medication of choice, methimazole (Tapazole), is administered as a long term maintenance treatment for hyperthyroidism. It may likewise be administered temporarily up until treatment with surgical treatment or radioiodine is completed. The normal dose is 5mg by mouth every 8 to 12 hours. Blood tests are normally completed every 3 to 4 weeks up until the appropriate maintenance dose is reached. A transdermal gel formulation may likewise be compounded by the pharmacist as well as can be administered to the hairless skin of the inner ear flap. Propylthiouracil (PTU) can likewise be used, however has higher incidences of side impacts as well as is as a result no longer suggested in utilize for cats.
Surgery: The thyroid gland can be removed. This is fairly risk-free if done by an experienced surgeon. like any type of surgical treatment there are specific dangers included with the anesthetics or from the procedure itself.
Radioiodine: In radioiodine treatment, the feline is provided a one-time injection of radioactive iodine. The radioactive bits concentrate in the thyroid as well as selectively irradiate as well as ruin only the thyroid tissue that is malfunctioning.
