Hyperparathyroidism results in elevated PTH and typically results in elevated calcium levels (hypercalcemia).
Primary hyperthryoidism is due to hyperfunction of the parathyroid glands, while secondary hyperthyroidism is a reaction of the parathyroid glands to hypocalcemia caused by another etiology, most commonly chronic renal failure.
Tertiary hyperthyroidism is due to hyperplasia of the parathyroid glands due to loss of response to serum calcium levels and this too is seen in chronic renal failure
Though most cases are asymptomatic, symptomatic patients can present with:
weakness and fatigue
depression
aches and pains
decreased appetitie
constipation
polyuria and polydipsia
kidney stones
osteoporosis.
Treatment options to be discussed next week....Stay tuned.
