Hypothyroidism :
Hyperthyroidism is a clinical syndrome due to excess thyroid hormone and its clinical consequences. It is the most common endocrine disease of middle-aged and older domestic cats. A silent killer, it relentlessly takes its toll on body organs.
What are the Symptoms and Signs of this Disease?
The clinical manifestations of the disease are multisystemic and relate to increased metabolic rate. Owners often overlook early symptoms or assume the changes are a normal part of the aging process. Obvious weight loss is usually the problem that takes the cat to their veterinarian. Other signs include tachycardia (rapid heart rate), muscle weakness, goiter, tachyarrhythmia (irregular heart rhythm), hyperexcitability, polyphagia (increased appetite), heat intolerance, increased frequency of bowel movements, polydipsia (increased thirst), polyuria (increased urination), vomiting, and an unkempt hair coat.
Left untreated, cardiac disease progresses to heart failure, hypertrophic cardiomyopathy and eventually leads to death. A few patients may be surprisingly asymptomatic despite severe chemical hyperthyroidism, particularly in the early stages of the disease (apathetic hyperthyroidism).
