Cat Hyperthyroidism Long-term Management

Feline hyperthyroidism is common in older cats and requires long-term management to maintain quality of life and prevent organ damage.

Key Facts

Untreated hyperthyroidism causes weight loss, heart disease, hypertension, and kidney stress
Medical management with methimazole requires twice-daily medication and regular monitoring
Radioiodine treatment offers a permanent cure with minimal side effects
Low-iodine dietary management provides an alternative for cats intolerant of medication
