Hypothyroidism
Hypothyroidism
Juga dikenal sebagai: Canine hypothyroidism, Thyroid hormone deficiency
Singkatnya
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. Defisiensi hormon umum yang sangat dapat diobati; obat harian pulihkan energi dan bulu.
Lesu dan bulu kusam mudah disalahartikan penuaan.
Apa itu?
Thyroid underproduces T4/T3; metabolism slows. Mostly dogs (lymphocytic thyroiditis or idiopathic atrophy). Rare in cats; often iatrogenic after hyperthyroid treatment.
Penyebab 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 adalah tanda kulit klasik.
Bagaimana dokter hewan mendiagnosis
TT4, free T4 by equilibrium dialysis, endogenous TSH, TGAA. Rule out euthyroid sick syndrome.
Panel tiroid lengkap mengonfirmasi diagnosis.
Pilihan pengobatan
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.
Kapan menghubungi dokter hewan
Check unexplained weight gain, chronic skin disease, persistent lethargy. Emergency myxedema coma: stupor, collapse, hypothermia, dyspnea.
