Cat Hyperthyroidism Quality of Life

Hyperthyroidism is the most common endocrine disorder in older cats, profoundly affecting their wellbeing if untreated.

Key Facts

Hyperthyroidism affects approximately 10 percent of cats over 10 years old
Symptoms include weight loss, increased appetite, restlessness, and vomiting
Untreated cats experience muscle wasting, heart disease, and hypertension
Treatment options include medication, radioiodine, surgery, or dietary management
Radioiodine is considered the gold standard cure with minimal side effects

Welfare Considerations

Treated hyperthyroid cats can enjoy good quality of life for years. Regular monitoring is essential as concurrent kidney disease is common and can be unmasked by treatment.

Discuss all treatment options with your vet including long-term management
Monitor weight and appetite closely in cats over 10 years old
