Hypothyroidism
Hypothyroidism
Juga dikenali sebagai: Canine hypothyroidism, Thyroid hormone deficiency
Ringkasnya
Hypothyroidism is a common endocrine disorder in dogs caused by an underactive thyroid gland. It slows down metabolism, leading to weight gain, lethargy, and skin issues, but is highly manageable with daily thyroid hormone replacement therapy.
TL;DR. Kekurangan hormon lazim yang sangat boleh dirawat; ubat harian pulihkan tenaga dan bulu.
Kelesuan dan bulu kusam mudah disalah anggap penuaan.
Apakah itu?
Thyroid underproduces T4/T3; metabolism slows. Mostly dogs (lymphocytic thyroiditis or idiopathic atrophy). Rare in cats; often iatrogenic after hyperthyroid treatment.
Punca dan faktor risiko
Primary gland damage common. Middle-aged dogs (often 2-6 y); genetic breeds may present earlier.
Tanda yang perlu diperhatikan
- Lethargy, weight gain, endocrine alopecia (common)
- Dull coat; pyoderma; hypercholesterolemia (common)
- Bradycardia; myxedema (occasional)
Alopecia ekor tikus ialah tanda kulit klasik.
Bagaimana doktor haiwan mendiagnosis
TT4, free T4 by equilibrium dialysis, endogenous TSH, TGAA. Rule out euthyroid sick syndrome.
Panel tiroid penuh mengesahkan diagnosis.
Pilihan rawatan
Lifelong Levothyroxine. Energy often improves in 1-2 weeks; coat over weeks to months. Retest T4 about 4-6 h post-pill.
Prognosis
Excellent with correct dosing. Daily lifelong therapy required.
Pencegahan
No primary prevention. Breeders: TGAA/thyroid panel. Interpret sighthound/Nordic T4 ranges carefully.
