Hyperthyroidism is the most common endocrine disease of middle-aged and senior cats, causing weight loss, hyperactivity, and potentially serious cardiac complications if untreated.
Feline hyperthyroidism causes chronic welfare harm through weight loss, muscle weakness, hypertension, and cardiac changes that progressively worsen if untreated. Affected cats are often ravenously hungry while losing weight, experiencing the welfare harm of chronic hunger alongside the physical deterioration of the disease. Fortunately, effective treatment options exist - radioactive iodine, medication, or dietary management - that can return cats to good health and quality of life when diagnosed and treated appropriately. Regular senior wellness examinations allow earlier diagnosis before disease progresses.
