    Hyperthyroidism in Cats

    thyroid gland becomes overactive, producing an excess of thyroxine hormone. This hormone regulates the body’s metabolic rate. When the thyroid gland grows excessively, it can lead to uncontrolled thyroxine production, putting the body in constant overdrive. If left untreated, it can be fatal, affecting organs like the heart, liver, and kidneys.


    Symptoms of hyperthyroidism in cats

    - Increased appetite with weight loss - Excessive thirst and urination - Decreased activity levels - Potential internal effects on organs

    How is hyperthyroidism diagnosed in cats?

    A confirmed diagnosis requires a blood test, but a vet can also identify signs during a physical exam. Additional tests, including weight and heart rate recording, urine analysis, and blood pressure checks, help gauge the disease’s progression and treatment effectiveness.

    Does hyperthyroidism need treatment?

    Yes, early treatment is crucial, even if the cat appears well. Hyperthyroidism may not show physical signs, making early detection and treatment vital.

    Treatment options for hyperthyroidism

    Medication: Regular administration, requiring lifelong commitment, with periodic blood tests to monitor effectiveness and side effects. Surgery: Removal of affected thyroid glands, usually performed one at a time to avoid complications with parathyroid glands. Radioactive iodine therapy: Safest and most effective, involving the administration of radioactive iodine to regulate thyroid hormone levels. Requires specialized treatment due to strict laws on radioactive substances. Diet control: Prescription diets with controlled iodine levels may be effective but require strict adherence.

    Side effects of treatments

    Medication: Temporary side effects like vomiting, loss of appetite, or itchiness. Surgery: Rare complications with calcium levels or wound issues. Radioactive iodine therapy: Generally safe with minimal risk or side effects.

    Complications and concurrent diseases

    Kidney damage: The longer hyperthyroidism goes untreated, the higher the risk of irreversible kidney disease. Heart issues: High blood pressure and strain on the heart can lead to heart failure, irreversible changes, and a guarded prognosis.
