Hyperthyroidism and Kidney Function: A Love/Hate Relationship

Kidney disease is a common concurrent condition in hyperthyroid cats (Dr. Peterson estimates that 20% to 30% of hyperthyroid cats have kidney disease). The increased cardiac output and hypertension caused by hyperthyroidism can increase the blood flow to the kidneys and can make them appear to be functioning almost normally. In these cases, once the symptoms associated with hyperthyroidism begin to diminish, the kidney function appears to decline. One method of detecting kidney disease in a hyperthyroid patient is to measure the levels of blood urea nitrogen (BUN) and creatinine by taking blood prior to the radioiodine treatment.
Many veterinarians choose not to treat for hyperthyroidism, thinking it will help the kidneys. However, hyperthyroidism is shown to worsen kidney function so it's important to stop the process by treating the cat for hyperthyroidism.
