Symptoms of hypothyroidism are rare but cats with biochemical levels of thyroid hormone that falls into the hypothyroid range is common. Iatrogenic hypothyroidism presents an increased risk of azotaemia and any cat with iatrogenic hypothyroidism should have doses reduced and close monitoring following this.
Dermatophytosis as a cause of alopecia is common in cats, too, and in long-haired varieties, dermatophytic pseudomycetomas may be to blame. [7] Alopecia areata has been studied on mice in laboratories. [8] In horses, human contact with the horse and the rubbing of the saddle across the mane can cause patches of hair loss. [7]

Certain medications can have the unintended side effect of affecting thyroid function. While some medications can lead to significant hypothyroidism or hyperthyroidism and those at risk will need to be carefully monitored, some medications may affect thyroid hormone lab tests without causing any symptoms or clinical changes, and may not require treatment.
Toxic multinodular goiter (TMNG), also known as multinodular toxic goiter (MNTG), is an active multinodular goiter associated with hyperthyroidism.. It is a common cause of hyperthyroidism [2] [3] in which there is excess production of thyroid hormones from functionally autonomous thyroid nodules, which do not require stimulation from thyroid stimulating hormone (TSH).
Hypothyroidism (also called underactive thyroid, low thyroid or hypothyreosis) is a disorder of the endocrine system in which the thyroid gland does not produce enough thyroid hormones. [3] It can cause a number of symptoms, such as poor ability to tolerate cold, extreme fatigue, muscle aches, constipation, slow heart rate, depression, and ...

To detect a lack of thyroid hormones (hypothyroidism), or excess of thyroid hormones (hyperthyroidism). The two thyroid hormones are Thyroxine (T 4) and Tri-iodothyronine (T 3). T 4 and T 3 can be measured by their total amount, or free amount.
