| 英文描述 | Primary hypothyroidism in the dog can result from autoimmune lymphocytic thyroiditis, iodine deficiency or excess, thyroidal damage due to neoplasia or infection, congential hypothyroidism, or idiopathic thyroid atrophy. Signs usually occur in middle aged or older females, but congenital hypothyroidism with dwarfism was reported. Secondary hypothyroidism due to a deficiency of TSH secretion and tertiary disease due to lack of effective TRH were also reported. Normocytic, normochromic anemia, elevated plasma cholesterol, and elevated plasma CPK are common. There have been reports of concurrent hypothyroidism and hypoadrenocorticism (polyglandular syndrome). Diffuse weakness is present in rare cases. |
