The type of vitamin D analogue used was not associated with outcome. How frequently should my dog’s blood calcium and phosphorus levels be measured. Heart rhythm problems, such as tachycardia. Results: Every breed of dog may develop this condition, but Keeshonds have a genetically transmitted form of this disease. The spontaneous disorder is uncommon in dogs and rarely reported in cats. This relatively uncommon disorder is a state of deficient secretion or action of parathyroid hormone (PTH), due to inadequate secretion, biologically ineffective hormone, or unresponsiveness of target cells (1). Sixteen of 17 dogs were treated successfully for hypocalcaemia and discharged from hospital. Primary hypoparathyroidism is an uncommon endocrinopathy in dogs, resulting from absolute or relative deficiency in the secretion of parathormone (PTH). Feline hypoparathyroidism occurs uncommonly. It is most commonly caused by an inappropriate immune system attack on the parathyroid glands.Inadvertent surgical removal may also occur during surgery on the adjacent thyroid gland(s), resulting in the same clinical signs.

In this article, we review the differential diagnoses in patients with hypocalcemia, the diagnostic testing to investigate clinical signs consistent with hypocalcemia, and the treatment of primary hypoparathyroidism. Of the small number of cases documented, hypoparathyroidism seems to occur more commonly in young to middle-aged mixed breed cats with equal representation of males and females 1. Primary hyperparathyroidism is an endocrine disorder caused by a tumor in the parathyroid gland and leads to an increase in blood calcium levels, or hypercalcemia. Saint Bernards, cross bred dogs, German Shepherd dogs and Terrier breeds were most commonly affected. Immune-mediated destruction of the parathyroid glands (the immune system attacks the body’s own tissues) is suspected. J Am Vet Med Assoc. Twelve dogs were alive at the last follow up and two dogs were euthanased for unrelated reasons. Hypoparathyroidism has been described in dogs in association to the atrophy or severe destruction of parathyroid due to lymphocytic parathyroiditis, enteropathy by protein loss, after laryngectomy, thyroidectomy and/or chemotherapy (Kimmel et al., 2000; Mellanby et al., 2005). If your dog has hypoparathyroidism the level of calcium decreases (hypocalcemia) which is a dangerous condition if not treated. , ~ , ~two most The common causes of primary hypoparathyroidism are idiopathic atrophy or destruction of parathyroid tissue From the Department of Medicine, (Peterson, Wallace, Joseph), The Animal Medical Center.

Other causes of seizures and weakness, like heart problems, neurological issues, and epilepsy, must be ruled out. In dogs, cellular infiltration (of a lymphoplasmacytic type) of the parathyroid glands is often found which suggests that immune-mediated process of parathyroid destruction may be a common route to hypoparathyroidism. Pets may exhibit signs of lethargy, little or no appetite, vomiting, and muscle twitching. Vitamin D supplementation is necessary to assist with the absorption of dietary calcium from the gastrointestinal tract.
