Renal Hyperparathyroidism: Metabolic Welfare in CKD Cats

Key Welfare Facts

Secondary renal hyperparathyroidism occurs when failing kidneys cannot maintain phosphate and calcium balance.
Elevated parathyroid hormone causes bone demineralisation, vascular calcification, and ongoing system dysfunction.
Clinical signs include jaw pain, loose teeth, and skeletal weakness progressing with kidney disease severity.
Phosphate restriction through renal diets is the cornerstone of preventing and managing hyperparathyroidism.
Calcitriol supplementation under veterinary monitoring can improve parathyroid hormone regulation significantly.
Regular monitoring of phosphate, calcium, and PTH levels allows adjustment of management before severe compromise.

Welfare Assessment

Secondary hyperparathyroidism is an underrecognised welfare complication of chronic kidney disease that worsens quality of life. Implementing phosphate restriction early and monitoring key biochemical parameters allows management that significantly reduces this additional welfare burden.

What You Can Do

Implement phosphate-restricted renal diet as early as CKD diagnosis to prevent hyperparathyroidism
Monitor phosphate, calcium, and PTH levels at regular veterinary checks in cats with CKD
Discuss calcitriol supplementation with a nephrology specialist for appropriate cases
Watch for signs of jaw pain or bone abnormalities as indicators of progressive skeletal welfare compromise
