When does feline hyperthyroidism begin? - in detail
Feline hyperthyroidism typically begins in middle-aged to older cats, with most cases diagnosed in cats over the age of 10. This condition arises when the thyroid gland, located in the neck, becomes overactive and produces excessive amounts of thyroid hormones, primarily thyroxine (T4). While the exact cause of hyperthyroidism in cats is not fully understood, several factors are believed to contribute to its onset. These include dietary influences, environmental exposures, and genetic predispositions. Cats fed predominantly canned or commercial diets may have a higher risk due to potential exposure to certain chemicals or additives. Additionally, exposure to flame retardants or other environmental toxins has been suggested as a possible contributing factor. The disease develops gradually, and early signs may be subtle, such as increased appetite, weight loss, hyperactivity, or increased thirst and urination. As the condition progresses, more severe symptoms like vomiting, diarrhea, and heart complications may emerge. Diagnosis is typically confirmed through blood tests that measure elevated levels of thyroid hormones. Early detection and treatment are crucial to managing the condition effectively and improving the cat's quality of life. Treatment options include medication, dietary management, radioactive iodine therapy, or surgical removal of the thyroid gland. Regular veterinary check-ups are essential for monitoring thyroid levels and adjusting treatment as needed.
