Hyperthyroidism is the most common endocrine disorder of older cats, causing chronic suffering if untreated. Effective treatment options significantly improve quality of life.
Untreated hyperthyroidism causes cats to waste away despite ravenous appetite, experiencing cardiovascular stress and hypertensive damage to kidneys and eyes. The condition progresses and worsens, causing significant suffering. Fortunately, effective treatments exist: daily medication, prescription iodine-restricted diets, or curative radioactive iodine therapy. Early diagnosis and consistent treatment restore good quality of life. Regular veterinary monitoring of older cats enables timely detection of this treatable condition.
