Endocrine diseases Flashcards
glands of the endocrine system
thyroid, pancreas, adrenal, and parathyroid
function of the endocrine system
produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, mood, etc
hypothyroidism
impaired production and secretion of thyroid hormone resulting in decreased metabolic rate
signalment for hypothyroidism
middle aged older dogs, breeds: golden, dobies, cockers
clinical signs of hypothyroidism
weight gain with no change in diet, PU/PD, “tragic expression”, lethargy, recurrent ear and skin infections, bilateral symmetric alopecia
Dx hypothyroidism
lab findings, elevated CHOL, decreased thyroid hormones, increased TSH
Tx hypothyroidism
lifelong thyroid hormones supplement
what do dogs look like with hypothyroidism
overweight, puffy face
equine hypothyroidism in foals
weakness, incoordination, signs of dysmaturity, enlarged gland
equine hypothyroidism in adults
exercise intolerance, lethargy, bradycardia, obesity, laminitis
Dx equine hypothyroidism
serum thyroid levels not routinely done
Tx equine hypothyroidism
thyroid hormone supplement
hyperthyroidism
the overproduction of thyroid hormone
causes of hyperthyroidism
adenoma (98%) and thyroid carcinoma (2%)
signalment of hyperthyroidism
middle aged to older cats
clinical signs of hyperthyroidism
weight loss, poor hair/coat, rapid heart rate, voracious appetite or thirst, anxiety or nervousness, diarrhea, vomiting, and vocalizing
Dx of hyperthyroidism
lump or mass on neck, elevated thyroid levels
Tx of hyperthyroidism
anti-thyroid medication, Sx, radioactive therapy
radioactive iodide
safe and effective treatment with cure rates of 95-98% while avoiding Sx, anesthesia, and thyroid drugs (can cause hypothyroidism)
thyroid disease in ruminants
enlargement of thyroid gland
cause of thyroid disease in ruminants
iodine deficiency
clinical signs of thyroid disease in ruminants
poor wool/hair, dry skin, enlarged thyroid, tendon laxity, reproductive failure
Tx thyroid disease in ruminants
supplement iodine into diet
diabetes mellitus
pancreas does not produce enough insulin
what is insulin used for
to help body use sugars, fats and proteins, without insulin sugar builds up in the blood and spills into urine
signalment for diabetes
middle aged to older cats and dogs
etiology of diabetes
overweight animals or animals with inflamed pancreas, glucocorticoids can lead to insufficient insulin production
clinical signs of diabetes
weight loss, cataracts, PU/PD, accidents in the house
Dx diabetes
serum chemistry elevated blood glucose
Tx diabetes
insulin therapy, diet change
uncomplicated diabetes
clinical signs of diabetes but not severely ill
diabetes with ketoacidosis
very ill with vomiting and depression
ketoacidosis Tx
IV fluids until vomiting stops
Tx for diabetes
insulin injection every 12 hours, dietary: high fiber, high protein
signs of low blood glucose
affects neurological function, disorientation, tremors, loss of appetite, lethargy, lack of coordination, weakness, seizures, discoloration of gums and skin
