The two main thyroid problems in cats are hypothyroidism and hyperthyroidism. In hyperthyroidism, a feline’s body manufactures too much of the thyroid hormone; in hypothyroidism, it produces too little. Hyperthyroidism is much more common, but hypothyroidism can become a problem for cats after they have been treated for hyperthyroidism. On these grounds, it's critical for cat owners to closely watch their cats after hyperthyroidism treatment
Cats that have hyperthyroidism will have an increase in appetite that is escorted with weight loss, sometimes spectacular weight loss. Cats with hypothyroidism will be likely to gain weight even though their food intake has not increased.
Diarrhea and vomiting may or may not take place in cats with hyperthyroidism. Felines that have hypothyroidism seem more prone to vomiting and constipation.
Cats with either type of thyroid problem can have lack luster coats, peeling skin and hair loss.
Cats that have hypothyroidism will have a decrease in action and will nap more often. They frequently seek out warm places to hide and rest. Things that would normally spark their curiosity and interest will no longer stimulate them. Cats that have hyperthyroidism are recurrently fidgety and edgy, with higher activity levels. Both types of thyroid problems can construct aggressive behavior in cats.
Cats that have hyperthyroidism will drink more and have more urine output.
Hyperthyroidism produces faster heart rates in felines, together with labored breathing, tremors and weakness. Cats that hypothyroidism can also experience weakness.
If your cat is displaying any of these symptoms, rush him/her to the veterinarian immediately for treatment.
