Parathyroid and Calcium Flashcards
PTH causes bone
resorption
PTH effect on Ca andVit D n the kidney
Reabsorbs Ca and adds second hydroxy group to D
Net total effect of PTH
increases serum Ca levels
Most common cause of Parathyroid hypersecretion of PTH
solitary adenoma
Vit D effect on Gut Ca
increases gut’s absorption of calcium and phosphate
Net effect of PTH on phosphate
Loss of phosphate because you piss it all out
Primary hyperparathyroidism clinical findings
Bones, Groans (pancreatitis), Stones (kidney, stomach ulcers) , Psychic moans
Previous severe bone disease found with high PTH levels
osteitis fibrosa cystica
Today high PTH people only present with
elevated serum Ca
Primary hyperparathyroidism mostly affects ___ bone
cortical
Symptomatic patients with these two symptoms are candidates for Primary hyperparathyroidism surgery

Asymptomatic patients younger than __, with severe ___, with reduced ____ clearance, and low __ __
50, hypercalcemia, creatinine clearance, bone mass
Secondary hyperparathyroidism is caused by the parathyroid glands compensating for
hypocalcemia
Secondary hyperparathyroidism causes
renal insufficiency, calcium malabsorption, Vit D deficecny
Tertiary hyperparathyroidism comes after prolonged __ and one of the glands goes rouge
Secondary hyperparathyroidism
