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.
There may be symptoms of thyroid overactivity, such as weight loss, a fast or irregular heart rate, tremor, and perspiration; [1] [2] but such symptoms occur in only half of all cases. [5] The most common type of hyperthyroidism, Graves' disease , may additionally cause eye problems ( Graves' ophthalmopathy ) and skin changes of the legs ...
More frequent bowel movements may occur, and diarrhea is common. Weight loss, sometimes significant, may occur despite a good appetite (though 10% of people with a hyperactive thyroid experience weight gain), vomiting may occur, and, for women, menstrual flow may lighten and menstrual periods may occur less often, or with longer cycles than usual.
Thyroid scans show minimal uptake during the acute phase due to disrupted thyroid follicles, but increase during recovery due to the thyroid gland's enhanced iodine trapping capacity. Thyroid ultrasonography typically shows thyroid gland enlargement and hypoechogenicity, while color Doppler ultrasonography may show low or normal vascular flow.
The virus is shed in feces, and cats become infected by ingesting or inhaling the virus, usually by sharing cat litter trays, or by the use of contaminated litter scoops or brushes transmitting infected microscopic cat litter particles to uninfected kittens and cats. [10] FCoV can also be transmitted through different bodily fluids.
Thyroid disease is a medical condition that affects the structure and/or function of the thyroid gland.The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ.
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]
[3] [5] [10] Even moderate weight loss can lower T3. [2] This may be primarily via reduced levels of leptin (the satisfaction hormone). Low leptin levels can downregulate hypothalamic TRH neurons and cause a reduction in TSH. [5] [10] Ιn fasting animals, administering leptin reverses NTIS symptoms and restores thyroid hormone concentrations. [5]
