Hypothyroidism
Hypothyroidism
Også kjent som: Canine hypothyroidism, Thyroid hormone deficiency
Kort fortalt
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. Vanlig, godt behandlingsbar hormonmangel; daglig medisin gjenoppretter energi og pels.
Slapphet og matt pels forveksles lett med aldring.
Hva er det?
Thyroid underproduces T4/T3; metabolism slows. Mostly dogs (lymphocytic thyroiditis or idiopathic atrophy). Rare in cats; often iatrogenic after hyperthyroid treatment.
Årsaker og risikofaktorer
Primary gland damage common. Middle-aged dogs (often 2-6 y); genetic breeds may present earlier.
Tegn å se etter
- Lethargy, weight gain, endocrine alopecia (common)
- Dull coat; pyoderma; hypercholesterolemia (common)
- Bradycardia; myxedema (occasional)
Rottehale-alopeci er et klassisk hudtegn.
Hvordan veterinærer diagnostiserer
TT4, free T4 by equilibrium dialysis, endogenous TSH, TGAA. Rule out euthyroid sick syndrome.
Fullt skjoldbruskkjertelpanel bekrefter diagnosen.
Behandling
Lifelong Levothyroxine. Energy often improves in 1-2 weeks; coat over weeks to months. Retest T4 about 4-6 h post-pill.
Prognose
Excellent with correct dosing. Daily lifelong therapy required.
Forebygging
No primary prevention. Breeders: TGAA/thyroid panel. Interpret sighthound/Nordic T4 ranges carefully.
Når ringe veterinær
Check unexplained weight gain, chronic skin disease, persistent lethargy. Emergency myxedema coma: stupor, collapse, hypothermia, dyspnea.
