Low Production of Parathyroid Hormone in Cats




Your cat may need to be hospitalized initially for medical management of low levels of calcium in the blood, at least until the clinical signs are controlled. Other treatment will be dependent on whether any other underlying conditions have been diagnosed.


Emergency treatment is usually only needed for certain patients, such as those with primary hypoparathyroidism, or hypoparathyroidism that is secondary to procedures that have been used to correct excessive levels of thyroid hormone or excessive levels of parathyroid hormone -- that is, procedures that have been medically used to lower the amount of parathyroid hormone in the blood, and have resulted in levels of parathyroid hormone that are now too low.


If your cat has been diagnosed with hypocalcemia, low calcium levels in the blood, your doctor will prescribe long-term treatment for the condition. Vitamin D will be needed indefinitely, with the dosage amount determined by your veterinarian, based on your cat's needs. Calcium supplements can be given by mouth, again, with the type and dose of calcium supplement directed by your veterinarian.


If your cat is suffering from hypoparathyroidism related to a thyroidectomy, there is a good chance that they will recover normal functioning of the parathyroid glands within several months time.


Living and Management


Both low levels of calcium in the blood and excessive levels of calcium in the blood are concerns that will need to be managed over the long-term. Initially, your veterinarian will want to see your cat frequently in order to follow your cat's progress and to make changes to care as needed. Once serum calcium is stable and normal, your veterinarian will assess serum calcium concentration monthly for six months, and then every two to four months.
